27" RCA stereo tv with PIP & Gemstar
model:F27668YX1,chassis:CTC203AA,year:Sept 2000. The customer who is on welfare took the tv to a pawn shop to pawn it and several months later when he had the money he took it home where the tv was sitting in a truck parked outside in -20 degrees Celcius.Instead of the customer waiting a few others for the tv to warm up he quickly plugged it in and the tv would not turn on until half an hour where then the power button on the tv would not turn the tv on except by using the remote control where the turned on but the menu screen kept scrolling down the screen. When the tv came to my shop it would not turn on so before I went further I decided to solder the following: T14101=SMPS x-fmr L14401=horizontal driver transistor base coil (removed it and scraped wax) R14158=243 ohm smt (in pip module) R141159=392 ohm smt (in pip module) RT14201=degauss thermistor T14401=flyback # 1536119A But tv would not turn on from remote on front customer control tact sw,I found 5v present at the tact switches and IR receiver,I could not find the input voltage at U14150=L78S75CV so I need a schematic for the whole tv.I removed the PIP module and still would not turn on.Thanks in advance.
