Sony projection tv...Screen blinks on and off to black several times a minute...audio and everything else is fine


It sounds like either the inverter board or lamp are the problem. I would sway more towards the inverter as when the lamps die they normally do it properly.

If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Dynex dxlcd32 tv not working


No, DX-LCD32 has a known problem with both the inverter and the CCFL lamps or, to be precise, the connections of those lamps, which tend to rust, desolder and break contact.

Doesn't mean that's the problem your TV has, but I am just noting that it is not the main board they are known to have a big problem with.

And the symptoms you describe would rather suggest a functioning main board than a bad one.

Lack of sound is probably simply because you're not having the TV on the right AV input.

Samsung hlp6163w dlp tv not working, new lamp, new ballast, still three blinking lights


If color wheel does not run lamp will not fire----with lamp removed have you looked at the wheel----if not running it will cause almost instant shutdown of lamp and the set.

If the DMD board is bad time for a new set as it is well over 500 .

Sony kdf-42e2000, lost picture and the 3 red lights started blinking. I did all the troubleshooting that have worked in the past, but no luck. Any ideas???


Maybe it's time to replace the lamp, have you ever changed the lamp on the TV before? If not, I recommend you do it, because it might be the main issue. Another thing can be the inverter board but you'll never know until you put another lamp in the TV and see for how ling it works, If it lasts less than 4 months, it will definitely be that board.

If TV goes off and the led stays blinking, that is because the TV is going on protection.
Protection is a special diagnostic mode that starts when an internal fault has been detected.
If this happens erratically while you are watching TV, then parts that can commonly cause the problem are PSU board, main board or digital board, ballast board and converge board on DLP, inverter on LCD, low buffer and sustain boards on plasma.
