Magnavox VCR VR9035AT01 with power-supply Assy. No. VEPS0198

Could you have a look at:

Any idea what that component labeled "PR1" is?

There's +5.2V on one side of it, open on the other.

This all started as my VCR started to die.

First, some tuner problems, then the lights on dim when things should have
been bright, then nothing at all, no signs of life. Enough problems to
have me look at the power supply first, but I can't fugure out what this
component is.

Any insight would be appreciated.

It looks like a "circuit protector chip", probably 1.5A:

The part is probably an ICPF38L formerly made by Rohm. Similar parts
(in different packages) are he

Many thanks, Franc!

This experience comes within a week of my Magnavox TV conking out. They
were both purchased at the same time - how's that for timing?

I had no horizontal sync, and quick look in the horiz. dept. revealed a
100uf 200V cap, whose vinyl sleeve had sagged to look like a Shar-Pei.

I'd hoped this would be another cake-walk. No such luck.

Something "out there" is cooking this CP-chip...

Thanks again,

- Ralph

A progress report.

I took out the PC Protector, and put a 3-amp fuse in series with my DMM,
and it only drew 0.31 amps when "off". When turned "on", it drew 0.36
amps.

The panel leds were not visible at all in "off" position, and very dim in
"on" position, which is not Kosher.

However, it was possible to switch the VCR on/off with the remote, which
is progress.

I guess whatever fried that PC Protector is now fried itself.

More sleuthing in the dark...

What's that green thing with red spots? It looks like a misplaced olive! :-)

A coil.

I had the gin & vermouth already poured, before I noticed it says "L3" on
the PC=board. So I'd guess it's a choke. (As in, "the choke's on me...)
