Sony 36" TV weird problems.

Model # KV36FV15. Unit has no raster, or audio, has a low "white noise" in the speakers, but has filiaments, & 30 KV high voltage. Turn up G 2 gives no vertical, not quite enough horizontal width, sometimes the lower half of the picture has raster, & retrace lines, & bad pincushion correction. I removed the rear vertically mounted A/V board, looking for bad connections, as it is a common fault. B + is 135 volts, & I have 22, -15, & 15 volts. The front buttons don't work, but unit comes on with a remote. Even with the remote, I can't get input access, or select vloume, channel etc. Led flashes continuously, no code.I read somewhere something about the data & clock lines, but it's really a stumper. Anyone see this very odd problem before? Thanks, Dani.

One voltage you haven't mentioned is 5 volts. There is a good chance this is not reaching certain places that it should. If this is missing it will also upset the clock/data operation.

Assuming all is ok with the above, Scope the field ramp waveform and if correct check the DC conditions around the field output stage. If all correct try changing the field output IC. If the ramp waveform is not right you need to investigate around the timebase generator.

I have seen these symtoms caused by a bad IC that contained the blanking circuits,video etc,it also had some bad filters connected to it
