Question about Sony FD Trinitron WEGA KV-36XBR800 36" TV
I have a Sony Triniton, I think it is the 36in model, and it will not turn on. When you go to turn it on it makes the sound like it is going to come on , but it does not. I will wait a while sometimes and try again, and it will turn on. There is a red blinking light that indicated stand by, and will blnk for 6 or 7 times. Do you have any ideas on this problem? Thanks
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.

I initially posted on July 20, 2008. At first started to panic because I wasn't sure it was still under warranty. Then started hyperventilating when I found out the place where be bought our TV (GoodGuys) was out of business. However, I called the number of the warranty and realized that it was still (barely) under extended warranty. I was expecting a big fight given that the place where we bought the TV was out of business, but no. A repair man showed up, counted the blinking light and said, "oh no. I'm gonna have to take it in." The repairman show up the next day with another guy ('cause as you all know, this monster weighs about 250 lbs.) and they hauled it down to the repair shop. A week later, it came back good as new. Hopefully, I'll get another five years out of this TV, but I'm not gonna hold my breath.
The guest that posted Solution #10 on October 12, 2008 refers to an excellent website http://www.techlore.com/article/15444/Understanding-Sony-Television-Blinking-Codeshttp://www.techlore.com/article/15444/Understanding-Sony-Television-Blinking-Codes that discusses the blinking light diagnostic codes.
My advise is that if you have an extended warranty, (even if it's already expired) that you try to get them to honor it. If you live in the Los Angeles, CA area, have the name of the repair shop that did the service and they were very prompt and so far (keep my fingers crossed) the TV's working just like new. If you nave more questions, you can email me directly at: [email protected]

I have a Sony trinitron xbr with the same problem the only difference its that the red lights don't blink at all , what is wrong with it? Please help

Generically, the 6 or 7 blinks usually indicate a problem with the horizontal circuit. In order to provide accurate diagnosis and suggested solutions, the exact model number is needed. Please update this with tha number and I will post more details.

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.
