Looking for a GE 9-7500 schematic

[t0nito]

Hi guys, I'm wondering if anybody can hep me find the schematic for this 1987 GE 9-7500 VCR.

The VCR's VFD isn't working but I found out that there is no power to the filaments. Both lines the filament go directly to the power supply and I'm trying to fix it, and a schematic would help alot.

Actually the is no voltage between the filament pins but there is 3.3V present from each filament to ground. If I short one of the filaments to ground the VFD will work but quite dim.

Here's all I know about the VCR:

It was built by Panasonic

It's virtually the same as a Panasonic PV-4720 but with a different shell.
I've seen two youtube videos of a 1987 Sylvania VCR and a 1987 JCPenny VCR with the exact same insides but the posters didn't say what model they were.

The main board has the following info:

ASSY.NO. VEPS0289

VJBS0289

MH437F

I've searched everywhere, can't find anything based on that info.

If a photos help to identify the VCR I'll post them.

Thank you.

Checked the Sam's website?

Looks like they have 204-page copies of the original GE manual available.
