Servicing 1988 Sony TV

[dtvmcdonald]

It returned from Andy today working nicely. He washed it in his ultrasonic, found
a few bad solder joints caused by the goo, found one more 105 degree cap
I missed, and then it had a raster but no picture. He remembered an identical
problem from another such set, and that was it: a shorted cap
in the video amp.

It works like new. The color line grid is very coarse and the purity on
saturated color screens not perfect, but the picture is quite watchable
on my local modulators.

The off the air reception is not great on our local Ch. 39 NTSC (HSN
shopping channel) with its built in antenna indoors, but its great
on the balcony. Moving around with this gizmo sure explains why
its so hard to get any picture on my RCA 3 inch ATSC portable.

Its fun to have a working CRT color TV that is not shadow mask.
