Good evening,
I have this 31" rca model F31671SE chassis ctc177cn , came
in dead, replaced U4101 (STK-730-010) with a new one but unsure of where it
came from, does not appear to be counterfeit, but after installing this ic the
set comes on fine, then in about 5 min the picture gets wavy lines in it and
eventually the picture goes in and out. When the TV is off raw 15volt source
goes from 15 volts to 20 volts and the b+ goes from 140 to 212 and then you
hear the buzz, turn the set on and the voltages go back to normal until you
turn it off again. Has anyone seen this problem before or anything close to it?
