Hi All,

I was able to isolate a fault in the RCA PFR 100 projection TV thanks
to a suggestion by James Sweet, The Drive transistor on the Red CRT
neck board was shorted out. After replacing it I see the image but
looks like the image is horribly out of convergence, but before I
attack that problem I need some advice on what I am seeing with the
service switch on.

There is a switch on one of the control boards to switch the TV to
service mode, I figured that in service mode I would see a single
horizontal line but what I see is

The contrast shows up better without the flash here

Can someone help clarify what could cause this behavior, also can
someone help me with the convergence tuning sequence. There is a row of
16 pots and maybe there is a way to quickly narrow down the
combinations.

Thanks
Jay
