32" Sony PIP stereo tv model:KV-32V16,chassis:SCC-F85R-A &
AA-1,year:Nov 1995.After about 3 hours of running or so the tv shuts
off and when power button is pressed the tv turns on for 1 second then
shuts off again,when power button is pressed again it turns of for a
few minutes then starts the process all over until the tv is allowed
to cool down for a few hours.
The standby LED light is not blinking so I cannot pull the codes,I
found extensive cracked solder joints throughout the unit and I
resoldered,the solder in the horizontal section was fine believe it or
not but I resoldered it as well.
This unit uses Flyback # 8-451-315-41 or 1-439-498-71
