I have a NEC FS5197 TV, which I tried to repair recently without a cct and failed. I have since tracked down a circuit and had another go, but argh I'm still having trouble!
The set has sound, no picture but the OSD works okay. Something is preventing the picture from appearing. Video from the tuner or AV input appears at the jungle IC: TB1226EN but doesnt make it out. My initial thoughts where faulty x-ray/protection cctry, but that seems to be okay. This leaves either a faulty jungle ic: TB1226 or faulty micro: M37212M8. Anyone got any ideas?? Unfortunately the set is old and not worth spending alot of money on it.
Thanks in advance TJB
