Try an isolated filament transformer before any rejuvenation attempts. I
have never seen a Sony tube hold up well after rejuvenation. It may look good
long enough for the customer's check to clear the bank, but they seem to drop
off
to a worse level in a short period. Two or three wraps of 22AWG thru the
FB/HVT iron core is a fast and reliable way to isolate the filaments. Scope the
filaments first and get the p-p voltage, then do the isolation modification.

Hi
This Sony TV model # KV-32S45 seems like has a loose connection inside
gun.First I thought it is a loose connection on crt board so I resoldered all
connections. The problem still there. By knocking to crt board, screen goes
blue and
tv shuts down. Sometimes screen stay blue for a few minutes. I never had case
like this. Should I replace the picture tube or there is a way to fix it ?
