Default Re: Philipps k35-No picture/sound

Hello ?,
Just a thought: Switch set off. Unsolder the back up battery and leave for a few moments. Resolder and try again. I had one of these stuck in standby after changing the battery, and it took me around an hour to trace the fault.

The micro might have 'glitched'. Failing this, I think the tuner should have two separate 12v supplies plus the varicap line [33v].
Does this voltage vary when you scan the tuning?

As for the colour drop out; does your version use a TDA3650 colour decoder chip? If so, it is probably plugged into a white holder. Remove the holder, shape the chip lead outs to fit the printed panel and solder it direct to the board.
That should clear up any colour oddballs. [This also applies to the CTX series] Do not twiddle anything...

Regards John.
