RCA Projo...dead.

[Dani]

I Got a call out of town on an RCA D52W15 ITC 222. Dead, power led
flashes three times & won't start, customer says it sounds like it's
trying
to come on. Ideas? Thanks, Dani.

Those flybacks are notorious for going also taking out the HOT..
That's a place to start first Dani

Take a 205064 HV splitter with you as well as a 47uf and a 470uf both
50 volt for the power supply in case. Measure the horiz. B+ while it's
trying to start. If it's in the range of 140 to 150, money's on the
splitter. If it shoots above 160vdc, change the caps in the power
supply.

Thanks Kip, I picked it up, & put the power supply/horizontal board in
another
unit, & it runs fine. All the boards check fine in another set, & even
with the
CRT's unplugged, it won't come on. To "Tech data guy"...wrong chassis.
This is the latest RCA 52" projo..not the old style. Thanks all the
same for
the input. Dani

PSSSSSSSST!!

This is for PTK169/PTK187 I think.

The ITC222 is completely and throughly DIFFERENT from old. 31KHz
horizontal frequency design, 120Hz vertical freq. Designed for HDTV
and upconverted low resolution signals.

Cheers, Wizard

My big ol bad on that one. Need to remember to read ALL the words in
the post. Good luck on that one. I finally got the one I'm dogging with
3 strikes your out as a shorted yoke. So , I get to order all three.
