Question about Sony FD Trinitron WEGA KV-34XBR910 34" TV

1 Answer

Tv doesn't respond to commands

We have a sony fd trinitron wega kv-34xbr910. We can turn on the power using the button on the tv (not with the remote) but it will only stay on one channel. We can't change channels or the volume, nor can we get it to video/game. The remote doesn't seem to do anything at all. Any ideas as to what is wrong? Thanks!

Re: tv doesn't respond to commands

Check the battery if its still good. if not replace with new one. if its still good, open the remote and inspect for loose connection. resolder if necessary. check also for possible crack pcb. good luck!

My remote worked fine, but suddenly won't work at all. TV is older Sony Wega 24" Trinitron (KV-24FS100). The satellite remote will change the channels, cause it's using the box, but it won't control...

Could be the IR receiver in the TV.
Make sure nothing is in front of the TV that would block the IR from receiving commands from the remote, I've seen customers put VHS tapes on the front of their TV that caused the remote to not to work.

Good luck

Apparently, channels have to be autoprogrammed first before those buttons will work.

Our TV is 4 years old but we never used the channel buttons bc it was always hooked up to DirecTv thru video input. SO when we disconnected the TV to sell, we thought it was a problem.

About Sony Trinitron KV-28LS36B

there are two possible defects in your circuit. 

However, if the led blinks for about 10 times your tuner is defective 90%. 

You will need a scope to check or you will need to take it in for service.

Sony KV-27FS100 does not respond to remote

Good day.

Maybe there are loose connections along the IC that supports the operation of your remote. This could also hamper initial set up operation of your unit. Also, check on loose connections along the power supply.
