Re: Vide problem

I think you have a problem in the vertical circuit in your tv. It sounds like you have a loose solder joint. The set would have to be taken apart and re-soldered. You really have an RCA chassis inside your tv. RCA's have a lot of bad solder connections. Stargazer

I have a Sony model KDF-e55a20. I just changed the buld but I still don't get any picture all I get is the power on light blinks 3 times. Does anyone know what the problem is?

Sir reset the lamp timer of your unit.
1 Press "Display" on the remote, followed by the 5 button, then the sound up key, and "power on". Do this while the tv is in stand by mode.
2 Then press "jump" 3 times to enter DE service menu.The tv screen will display the total lamp time hours.
3 Reset the the lamp time by pressing channel 3, then mute, then enter.This will return lamp timer back to 0. Hope this may help good day and best regards.

Picture-in-picture won't go away

Does this happen with TV signal only, or with other inputs as well?

No picture-rumbling sound

From the symptoms you describe, it seems the high voltage flyback autotransformer has failed along with the horizontal amplifier (they are slaved to each other). The sound comes from the flyback unit.

Well, the only way to solve this is to get a technician take a look at the set, I'm afraid. Repairs could cost upto $100 or more, depending upon the number of components that need to be replaced,

It may be worth getting fixed up. If you decide to do so, call around, as shops have different rates and different expertise.

Hope that helps!

TV Screen (Display) has been shifted 2" upward

Some and not all have a return to factory setting option. see if you can find it and this might be an easy fix if not I would try to see if the bulb was out of place. that is if your tv uses one.
Good luck.

Tv problems


I am assuming that you are using cable and not an aerial/antenna.

On your concern "...channels do not tune...correct channel numbers...", it is possible that when you re-tuned the TV your setting was set to AIR or STD, try to re-tune again but this time pls verify that you are in CABLE mode. If on the other hand you are using aerial/antenna, then it is the other way around.

Channel 0 would automatically be your Audio/Video (which is where your DVD/VCR is connected). If you re-tune, chances are that Channel 0 ) would be back. To be on the safe side, pls power on likewise the DVD/VCR.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
