SONY Trinitron Wega KV-36XBR800 not working

Diagnostic light blinks seven times, stops, and then repeats. I have unplugged set from power strip and used wall outlet, but it still does not turn on. Any ideas?

    Thank you very much. 7 blinks indicates a "temperature" problem with the suggestion to clean the vents, which I did. That solved it. The SONY Trinitron is an excellent machine, still, after 13 years, and it is fortunate that I got it to work with advice from FIXYA.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sony xbr6 standby light blinks 14 times, pauses and repeats


Just count the number of blinks occur at one time. 14 blinks to trinitron TVs are not possible. It might be 10. If so,
  1. 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. If you wish to know more about blinking codes to Sony Trinitron models TVs, check this link. If it is Intermittent problems? This is a great feature. You can also bring up these fault codes on-screen to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, press the following buttons: Display, Channel, 5, volume Minus, ( not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problems named, are abbreviated as, "OCP", "OVP", "V STOP", ETC. We have repeated them in parentheses in the text for the "Blinks" described above so you can correlate between the diagnostic screen and the blink codes.

Light blinks 7 times when i try to turn it on. sony kv 36xbr800


Are you sure it isn't eight......try turning on this method....display, 5, vol+, power on. Should bring it on in the diagnostic mode. Mine and about kazillion other owners have the same problem, bad M board and they never issued a recall on it. Costs 2-300 to have someone repair it, cause its' too heavy to carry it in, I think they used cement in the bottom for weight.

Sony Vega Service Codes


KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.
