Hi guys , I was wondering if anyone can lead me in the right direction
before I tackle a repair , I have a Sony KV-2566as television with
sound but no picture , I think it might be a faulty EHT but I have my
suspiscions it might be an over voltage protection zener that has gone
S/C , regards

Diagnostics would be an assistance to help us assist you. Lousy solder
connections in the power supplies, deflection circuits, etc. Seen many of
the SONY sets here in the US having very poor connections at the LOPT,
H-Driver XFMR, Etc. Cheers
