Model WTV-61904, mfd. Dec. 1999. Comes on for a second or two and goes
into HV shutdown. Sometimes it powers and runs for several hours without any
problems. I tried replacing the STR regulator this made no difference.
Powering with a Variac at 100VAC eliminates any problems. What other causes
should I be looking for, or is there an easy way to simply bypass the HV
shutdown? The shutdown feature is part of the TA1268N video IC, but I need a
pinout to determine which pin to disconnect.
Also this set was used very heavily, about 20 hours a day since it was new
(or so the owner tells me). Probably worn out anyway.
Thanks for any advice.
