Re: Recapped Genesis

This is the motherboard as it is today. I've extremely hacked it.. Overclocked, region modded, sound chip upgraded (to a mostly compatible part that has same features but better, but not 100% object compatible, requiring an elaborate piggy backing chip hack), and CPU upgrade to a military specced 68000 (just for kicks no benefit really).

Re: Recapped Genesis



It's a Model 1 Genesis, VA3 motherboard. Those are from around 1990.....

Not exactly a computer motherboard, but it is my Sega Genesis motherboard.

The difference new caps made, was huge.

Oh yea, new caps for the win, and I used only nichicon, panasonic, and united-chemicon..https://Not exactly a computer mothe...d united-chemi

Re: Caps that appear fine still

This one doesn't auto mute, it's a rather crude and simple TV.. It has VHF and UHF knobs on it..

But, the dc coupling capacitor, this would be interesting to look into.



That's the schematic to the chassis on this TV.. The last pages are for the digital tuning some models of the TV had, but mine doesn't have that so only the main board's schematics are true.

Re: Caps that appear fine still



I never measure in circuit, too many variables can affect the outcome. I removed them from circuit.

This was tested though about a year and a half ago when I got the TV....

So I have an old television from around the early 80's. It's an old Samsung with Samwah and Samsung branded caps. The caps appear to be running completely fine still, even after many years of service. The picture is strong, bright, and vibrant. Only oddity is the speaker has a slight buzz to the vertical refresh rate (60Hz on NTSC sources and 50Hz on PAL sources). This to me inclines one of the caps may be going out of tolerance, but everything looks great inside, no buldges, nothing leaking, and when i run an ESR test on each cap, they actually pass.

If they still pass an ESR test...

Re: New Members - please post your introductions here

Hello guys, just joined.. Have dealt with bad caps for so long including a 2008 Samsung LCD, that Samsung refused repair on, and after I repaired it myself by replacing a few caps, and replacing a mainboard it destroyed, Samsung then offered free repair, but wouldn't pay me back as I repaired it myself.. (this was a couple years ago, TV still works today, haha).
