Good Day..

Have anyone knows what seem to be the problem? And can give me
tips how to troubleshoots Sonny TV 25" model KV-25FX1? When i turn on
the power theres no display on the screen, i can adjust the volume,
change channel and select either tv or video but theres no any display
on the screen..I can hear only the audio that confirm all the key
button is working ( for ex..when i adjust the volume and change
channel).

there are several ways to land in hospital lurking inside tvs, plus a
couple of ways to land in a coffin, so if yuo dont know where to begin
I'd leave it alone.

If and only if you do know the risks and how to not get caught by them,
I'd start by looking at the supply lines, listen for EHT, then check
the tube electrode voltages.
