This RCA DTV306 38" direct view wide screen HDTV powers up with HV, CRT heaters lit and both fans running as soon as its plugged in. The power button turns the power light on and off, but there's no other noticeable effect. Turning up the G2 control reveals a sharp vertical line about 4" long. There's zero horizontal sweep. It never goes into shutdown. There's no sound, but without seeing a picture, there's no way to tell if there should be any sound.
It appears to have had the standby power supply diode upgrade and I've checked for obvious things like bad soldering, shorted HOT, swollen caps, cracked PCB,... The standby power supply is working and there's about 75v on the C of the HOT. There's no horizontal drive. Before I do anything else, has anyone seen this problem before? I realize this is a very complex chassis, but I would rather not buy a service manual if I can avoid it. Andy Cuffe
