Sony Bravia KDL-52XBR9
There is a error in TV.Count how many times blinking the red light.
- Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
- Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
- One blink - not used for the self-diagnosis
- Two blinks
- B+ over current protection (OCP), unit goes to the standby mode then
displays the 2 blink fault. Could be a short in the power supply of any
of the circuits.
- Three blinks - B+
over voltage protection (OVP), unit goes to the standby mode then
displays the 3 blink fault. This is also a problem in the power supply
circuit, check T603 and R672.
- Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
- Five blinks
- AKB circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761 and
other components on the C board, also check Q218, 219, 220 on the A
board. In addition, unit could be in IK blanking, try turning up screen
- Six blinks - No Horizontal
(H STOP), no raster, goes to the blinking self-diagnosis function
immediately. Check C515 & 516 and the jungle IC, IC206.
- Seven blinks
- High voltage shutdown. The high voltage has exceeded 33k and the unit
goes immediately into safety shutdown. Check power supply regulation
and horizontal circuits.
- Problem with the audio (AUDIO), unit goes to standby and blinks the
self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some
projection models of Sony TV sets, this code means that T8005 (flyback
transformer), or the associative components in the high voltage
circuits are defective on the D board.
- Nine blinks
- Replace D 6116 and D 6301 on the "G" board, do not resolder as this
will fix the problem temporary. Or Panel Module Error or Thermal Error.
If it is intermittent 9 blinks, meaning sometimes the TV comes on and
other times you get flashing, then change the switching regulator on
the "G" board or check connections. Make sure the regulator is -12 or
- Ten blinks -
Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on
the " D" board. If the transistors are bad, check R8051 and IC8005,
also on the "D" boards

TV screen is black but sound works on all devices.
Do you have a "cable-box" that feeds your TV?
Some older cable-boxes cannot decode the newer 'MPEG4' (compressed video) video that some cable-companies use for some of the channels. So, you get "black-screen", since the audio-stream is NOT compressed.
Talk to your cable-company, to upgrade to the newest cable-box.

I have a Sony KDL-52XBR6. It has horizonal lines
Based on the information you've provided, I suggest that you update the TV with the latest System Software and check the operation. I've provided a link with the information to download System Software Update:
If the issue is unresolved, please follow the additional steps given below to troubleshoot the issue:
1. Make sure that you have connected the source to the Television properly and securely.
2. Unplug the power cord of the unit from the wall outlet for few minutes, then connect it to a different wall outlet and check the operation.
3. Connect the video source to a different input on the Television and check the operation.
4. Connect a different video source to the Television and check the operation.
5. Replace the connecting cable and check the operation.
6. Reset the TV to factory settings. To reset your TV to factory settings, turn the TV ON. Then, while pressing the UP ARROW or RESET button on the remote control, press the POWER button on the TV. The TV will turn itself OFF then back ON.

I started having vertical lines on my screen whick first it was only around the upper corner edge
I would suggest that you check ribbon connections between t-con and LCD panel. Also I would have you power supply checked. Unclean sources from the power supply can cause all kinds of strange video problems. If the power supply checks out fine, and the t-con/LCD panel ribbon connections are ok, I would suspect a faulty LCD panel. You can try replacing the t-con, they should be cheap enough to take the gamble. But if you don't want to gamble, get a diagnoses done on the set.

3 blinking red standby lights,
Hi, shutdown with a 3x blink pattern occurs if the 12v from the power supply (GF1 or GF2 depending on model) is lost at CN6153/pin 6 to the AU Board Q1224 to Sub Micro IC1205. The suspects, in order of likelihood, are (1) Power supply and (2) the AU board.
