WARNING AND CAUTIONS
CAUTION
These servicing instructions are for use by qualified service personnel only To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so.
WARNING!!
An isolation transformer should be used during any service to avoid possible shock hazard, because of live chassis. The chassis of this receiver is directly connected to the ac power line.
! SAFETY-RELATED COMPONENT WARNING!!
Components identified by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for safe operation. Replace these components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony. Circuit adjustments that are critical for safe operation are identified in this manual. Follow these procedures whenever critical components are replaced or improper operation is suspected.
ATTENTION!!
Ces instructions de service sont lusage du personnel de service qualifi seulement. Pour prvenir le risque de choc lectrique, ne pas faire lentretien autre que celui contenu dans le Mode demploi moins que vous soyez qualifi faire ainsi.
Afin deviter tout risque delectrocution provenant dun chssis sous tension, un transformateur disolement doit etre utilis lors de tout dpannage. Le chssis de ce rcepteur est directement raccord lalimentation du secteur
! ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!
Les composants identifies par une trame et par une marque ! sur les schemas de principe, les vues explosees et les listes de pieces sont dune importance critique pour la securite du fonctionnement. Ne les remplacer que par des composants Sony dont le numero de piece est indique dans le present manuel ou dans des supplements publies par Sony. Les reglages de circuit dont limportanceest critique pour la securite du fonctionnement sont identifies dans le present manuel. Suivre ces procedures lors de chaque remplacement de composants critiques, ou lorsquun mauvais fonctionnement suspecte.

SAFETY CHECK-OUT
After correcting the original service problem, perform thefollowing safety checks before releasing the set to the customer:1. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for soldersplashes and bridges.
2. Check the interboard wiring to ensure that no wires arepinched or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps,and mounting hardware have been replaced. Be absolutely cer-tain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly transis-tors, that were installed during a previous repair. Point themout to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious signsof deterioration. Point them out to the customer and recom-mend their replacement.
6. Check the line cords for cracks and abrasion. Recommend thereplacement of any such line cord to the customer.
7. Check the antenna terminals, metal trim, metallized knobs,screws, and all other exposed metal parts for AC Leakage.Check leakage as described right.
LEAKAGE TESTThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn to chassis, must not exceed 0.5 mA (500 microamperes).Leakage current can be measured by any one of three methods.1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers instructions to use theseinstruments.
2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The limit indica-tion is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-amples of a passive VOMs that are suitable. Nearly all batteryoperated digital multimeters that have a 2 V AC range are suit-able. (See Fig. A)

2-2. TROUBLESHOOTING
Twin ViewProblem Possible RemediesI cannot get Twin View to work s If you are using a cable box to unscramble all channels (as shown on page 26), you
cannot use the Twin View feature. This is because the cable box can unscramble only one channel at a time. But if you need the cable box to unscramble only some (usually premium) channels, you can use Twin View for unscrambled channels if you connect both a cable and cable box, as shown on page 25.
s You can use Twin View to view a signal from a different source that is connected to the TV's A/V jacks (such as a VCR or DVD player) in the second window by pressing the TV/VIDEO button while in Twin View.
s Digital sources, as well as any sources connected to the VIDEO 4, VIDEO 5, VIDEO 6 inputs, display in the left window, but not in the right windows.
There is no Twin View window, or it is just static
s Be sure the Twin View window is set to a video input or channel that has a signal airing.
s You might be tuned to a video input with nothing connected to it. Try cycling through the video inputs by pressing the TV/VIDEO button.
Twin View cannot display anything but TV channels
s Try cycling through the video inputs by pressing the TV/VIDEO button. Check that the Label Video Inputs option is not set to Skip. (See the Setup Menu on page 105.)
Twin View displays the same program in both windows
s Both Twin View windows might be set to the same channel. Try changing channels in either window.
Remote Control
CableCARD
Problem Possible RemediesRemote control does not operates The batteries could be weak. Replace the batteries.
s Check the orientation of the batteries.s Press the TV (FUNCTION) button. You may have inadvertently pressed the
SAT/CABLE (FUNCTION) button, which changes the remote control to SAT or CABLE mode.
s Make sure the TVs power cord is connected securely to the wall outlet.s Locate the TV at least 3-4 feet away from fluorescent lights.
Cannot change channels with the remote control
s If you are using the TV to change channels, first press the TV (FUNCTION) button.
s If you are using another device to change channels, be sure you have not inadvertently switched your TV from the channel 3 or 4 setting. Use the Channel Fix option to f ix the channel based on the hookup you used (see page 99).
s If you are using another device to change channels, be sure to press the FUNCTION button for that device. For example, if you are using your cable box to change channels, be sure to press the SAT/CABLE (FUNCTION) button.
Remote control does not operate non-Sony video equipment
s If you replaced the batteries to the remote recently, the code numbers for the video equipment may need to be reset.
s There may be more than one code for the equipment that you are attempting to operate.
s There is a possibility that some non-Sony equipment cannot be operated by your Sony TV remote.You may need to use the equipments original remote control.
Problem Possible RemediesProblems using CableCARD or CableCARD services
s Check that the CableCARD is inserted properly (see page 51).s The CableCARD must be activated by your local cable TV provider before you
can receive digital cable TV services. See the activation instructions on page 51.s Check the Diagnostics and CableCARD menu options (see page 108). (This
can be useful in providing information to an authorized technician or repair person.)
s Contact your cable TV provider.

s Press ANT to select the VHF/UHF input (see page 57).s Use Auto Program in the Channel Menu to add receivable channels that are not
presently in the TVs memory (see page 99).TV is fixed to one channel s Use Auto Program in the Channel Menu to add receivable channels that are not
presently in the TVs memory (see page 99).s Check your Channel Fix settings (see page 99).
Cannot receive any channels when using cable TV
s Use Auto Program in the Channel Menu to add receivable channels that are not presently in the TVs memory (see page 99).
s Press ANT to select the CABLE input (see page 57).Cannot receive or select channels
s Use Auto Program in the Channel Menu to add receivable TV channels that are not presently in TV memory (see page 99).
Some digital cable channels are not being displayed
s Certain cable TV companies have limitations on the broadcast of digital cable channels. Check with your cable TV company for more information.
s Check with your cable TV company if the channels are scrambled or encrypted. You will need a CableCARD or a separate set-top box to view those channels.
s Some optional digital cable broadcast formats may not be supported. If your cable TV company is broadcasting digital signals in unsupported broadcast formats, you will need a separate set-top box provided by your cable TV company to view those channels.
s The digital cable channel may be set to Hide in the Channel Menu (see page 99).s Use the Digital Channels feature to search for new digital channels (see page 99).
Memory StickProblem Possible RemediesImage does not display/Cannot see all files
s Make sure the image file is a JPEG (.jpg, .jpeg) file or an MPEG1 (.mpg, .mpeg) file.
s Make sure the Memory Stick is inserted properly (see page 78).s Check the Filter option setting (see page 89).s Check the Select Folder setting (see page 89) and ensure that files are either in
DCF directories if Digital Camera Folders is selected (see page 89), or in the currently selected folder if Select a Folder is selected (see page 89).
s The maximum number of files the Memory Stick Viewer can display is 2,000 files total, including all JPEG, MPEG1, and MP3 files.
s If you are using a Memory Stick with the Memory Select function, try changing the position of the A/B select switch.
JPEG image displays undesirable motion or flicker in full screen
s JPEGs captured using a digital video camera may appear to display motion in full screen. This is a result of the way digital video cameras record still images, and is not a result of a malfunction with the TV.

Bars appear at the top and bottom of the screen
s Some wide-screen programs are filmed in aspect ratios that are greater than 16:9, such as 2.35:1. (This is especially common with theatrical releases). Your TV will show these programs with bars at the top and bottom of the screen. For more details, check the documentation that came with your DVD (or contact your program provider).
Certain programs on DVD or other digital sources display a loss of detail, especially during fast-motion or dark scenes
s The compression used by certain digital broadcasts and DVDs may cause your TVs screen to display less detail than usual, or cause artifacts (small blocks or dots, pixelations) to appear on your screen. This is due to your TVs large screen and ability to show very fine detail, and is normal for certain digitally recorded programs. Adjust the reality/clarity in the DRC Palette option (see page 93) to optimize the picture while viewing these sources.
