I have a sony crt tv (kv-G21P2) this tv pictures ok, but sound not working . Speaker good. Not coming any noise . Not working sound how fix this?

Check its speaker first. It sounds that the speaker is out. If it is found OK, check for any loose solder terminals at the audio output section circuit, of damaged component/s there.

HELLO MIKE

I don't think your TV is totalled! It's more than possible that a speaker connection on the main board has come adrift and just needs pushing back in. Check connections on the speakers themselves and when you trace back the cables there will one or two push in connectors.

It may be a good idea to get the speaker connection plugs checked and resoldered. It is also possible that the fall could have jolted the audio IC and this should be checked for dry joints or cracked print on the board too.

Hope this helps (:-)

try to adjust the screen. it is located behind the CRT board.(CRT board is the board that attached to the picture tube) you will find a black knob which label screen adjust it by turning the knob.

I suspect you crt tube is going and is most likely not worth fixing

There are things you could do a tv service shop could rejuve your picture tube and adjust your screen voltage.

sometimes that does not work

I would start looking for another tv



thanks doctor video

Usually, the CRT is bad......re-juvenation is a temporary fix at best........try adjusting screen control on CRT socket module.

Only other possibility is solder pins of vertical output IC.

HI,YOUR PROBLEM IS ON THE FLYBACK TRANSFORMER OF YOUR TV. YOU MUST REPLACE THIS BUT BE VERY CAREFUL REMOVING THE FLYBACK.

as sound is ok means power supply is ok. 1 check for filament if it is glowing means it is ok otherwise check for its supply. 2 check video and crt pins voltages 3 check for connector loose 4 luminance section in chroma ic. good luck

I have a KV-27V55 and when I turn the TV on the picture and sound is good for about 30 minutes and then the picture goes off, but the sound is still on. It will come back on after a while.  What do I do?

You likely have bad solder connections around the tuner area. This model has a history of problems in that area or the tuner itself.
