Question about Sanyo DS27510 27" TV
If the picture is roaming as you say then check to see if you have 33 volts on one of the pins of the tuner. If not this will trace across almost the whole board to a resistor: some models will be 39k and other will be 27k. May be (don't remember exactly) R106. Anyway there will be 130 volts on one side and 0 on the other. This feeds the tuning voltage to the tuner 33 volts. I have seen it where the picture is not there at all and sometime I have seen it as you say sort of roaming off frequency. Hope this helps
