I have Sony Trinitron XBR 36 Inch model. Purcahsed in 2003 and all of a sudden last monthstopped working. When we turn it on we get 7 blinks and then 6 blinks sometimes. What could be the problem. Anybody has same kind of issue if so could you please share the solution to this problem.
Sony had a recall for that tv back in 2009 or 2010 I think. There are 2 diods on the main power board that are known for failure. Take the tv to a repair shop or replace the primary power board yourself.
Best thing to do is get 3-4 people to haul it to the curb. That is a high voltage failure which can be related to a bad tube or flyback. That TV is too old to get parts for and not worth spending a single dime on.

posible solution is adjust the screen to low.also check the trimer if it is working.check the resistor in the heater line...weng

break the wega into tiny little pieces and it's easier to get out of your house!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The 6 or 7 blinks usually indicate a problem in the horizontal circuit. Since the TV recovered once, the problem is most likely to be a bad solder connection in that area. If you can solder, resolder any connections on the board that appear grainy or have rings. That may resolve the problem. If not, update this and we'll look elsewhere for defective parts.

Many of the later model Sony TV?s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it. The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again. Here is a list of the problems that might have occurred indicated by the number of blinks. The words in parentheses are those, which you will see for each of these faults on a diagnosis screen described later in this article. 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 slightly. 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. Eight blinks - 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 -13 (negitive). 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" board.

pls. use remot menu key and open main menu use DW key and select system menu see the PIP option is "ON" set option is"OFF" .
See the PIP screen is clear.
