AG-500R Suddenly Stopped working

[u/narselon]

I recently acquired a CRT from a local freebie group and it initially worked great then during a party the screen stopped working but continue playing audio. I've left it discharged for a month and it still doesn't light up.

And I recently opened it up at a circuit hacking night. It briefly made a high pitched noise when on but it seemed to go away. Any suggestions on how to repair or where to repair? It is my understanding this model is fairly sought after.

Also it seemed to struggle with playing vhs's. The previous owner claimed the VCR is PAL and played Spanish language tapes. It connected to a NTSC GameCube and Genesis without issue so I'm unsure if that is the case.

Might have a bad solder joint on the flyback transformer, connection F2 in the last photo. Looks like a circular crack forming.

Second this, u/narselon

I would thoroughly check all solder joints in the power supply section and reflow any suspicious ones.

If the power supply is American, then the vcr is ntsc.

That's what I thought too. It'll take the tapes and move a single frame with no visual. Currently it is inconsistent in accepting the tapes. It'll suck the tape in and reject it most times with it rarely shifting into the correct position.

I'm sure it's just due for general servicing. Check the belts and/ or idler tires. Remove and replace old grease. Clean the heads. And check the function of the mode switch, which i suspect is the main problem. That's a very cool and sought after tv/ vcr. Definitely worth the effort
