SOURCE: Power light flashes 4 times

The 4 blink code usually indicates a loss of vertical deflection. Check the solder connections on the vertical IC. If the connections are OK, replace the chip as it is defective. This chip will be a small flat IC with about 1 pins or so attached to a heatsink. It will be marked LA3847 or something similar.

Keep us posted.

SOURCE: TV won't stay on

Hello Fonzell!
Regarding the tv turning, my question is, do you hear a clicking sound? if so, it's most probable tio be your ballast, that might not have enough voltage to keep on with your lamp, and that's why it shuts off.
You could try replacing it and seeing if it resolves your issue, I believe they're running around 70 dlls..
have a great one ! :)

You have a problem in the vertical drive section. Probably need to replace the vertical IC and maybe associated resistors. Let me know how you make out.

The flashing light red power light should only stay while the fan cool down for about 1 minute after a power off (remember to always wait before unplugging the TV so the lamp can cool down with the fan). Does that flashing start right away after plugging back the TV after an hour of letting it without AC power.

The red light should flash no longer than 10 sec. This prepare the light to be turned on. If all is OK the green should stay (no longer flashing) and the sound and picture come on.

As for the lamp flashing, i bet it's only 1 time each 5 sec? Or do it group many rapid flash each 5 sec?

Things that can be wrong:
-the fan lamp

-the lamp is not proprely inserted (wait an hour before manipulating it to be sure it cooled down, and use glove to not put body oil on it).

-Lamps is defective and is not operating properly so you can't get to the usual on screen message that recommend to change the lamp.

KDF-55WF655 Power Issues


Solution # 1 was no help - I talked to some moron at Sony who said to contact a service person. Waste of 30 minutes.

Here is what I did:

I was having the same problem. I am no expert, but what I read on-line is that it was likely the lamp needing replaced, that the lamp toward the end of its life will flicker and cause the TV to "reboot". I had no Red Lamp replacement light, so I wondered if that was really the problem. But, I bought a replacement lamp for $110 plus shipping, and replaced it last night - TV is working great now. I would try replacing the lamp on yours first yourself (if the lamp is older than 2 yrs), then if that does not work, contact a service person. Don't have a service person replace it, because I have heard many people say they paid $400 for a replacement lamp service, and I did it for under $140 with overnight shipping charge for the new lamp. My original lamp lasted 4 years, so I was lucky to not have this problem sooner. As long as the green light is flashing more than 10 times before the picture comes back on, it is likely the lamp. For 10 or less flashes it could indicate another problem.

Hope this help!

My sony tv will not stay on


If you replace the lamp and need to reset the Lamp Timer Reset procedure is: With The Set In Standby Press Display, 5, Vol Up, Power on the remote control Press Jump 3. Or, To Display The Lamp Time Press 2 Nine Times. To Reset Press 3, Mute, Enter. One of these should work on your model. Make sure you replace the bulb first. There is a possibility that the ballast could be damaged by a defective bulb as well.
