2 of the 4 screens I ordered arrived smashed Darn you postal service!

all have continuity... Itll be heart breaking to junk this system when its so close to working, but unplayable is unplayable. Thanks for your help

went to desolder U10 wasnt paying attention and desoldered U9 instead cursed a lot went to resolder U9 dropped it off the table into carpet cursed a lot found and resoldered U9 desoldered U10 soldered a jumper from pin 9 to pin 12 where U10 used to be same static audio issue

any updates?

well after waiting several weeks for a replacement U5 to arrive, I replaced it... and it still has the same issue... Thoughts?

5v supplied to U5 and 3.3v on R64 and 65. sadly I dont have a scope yet so I guess I'll just go ahead and try to replace U5. They seem to be around $5 on ebay so no big loss if it doesnt help. Thanks for your help. I really appreciate it.

Well I soldered on some wires to pins 6 and 8 and connected them to some powered speakers. Yes, pins 6 and 8 are producing static hiss with game sounds barely audible underneath Would that mean U5 is most likely needing to be replaced or something further back in the line?

is it a line level audio signal coming out of those pins? trying to figure out a way to check them without a scope.

using a genuine power supply that works fine with other systems

2 different tvs and the guy I got it from said it did the same so thats at least 3 different devices

any idea what might be causing that?

I picked up a Jaguar that has the R/P board. Everything seems to work but theres terrible static over the top of any sound thats played. Its not static all the time, just when a sound is played. It does it both on RF and with one of those composite adapters. Reg1 is outputting 5v as normal and the whole board is recapped. I thought it might have been an issue with the cap job but that turned out not to be the case after further investigation. All the caps are the correct rating and seem to have intact traces. I posted a video to the consolerepair subreddit if that helps. Thoughts?

I'm in for at least 4

Last week I picked up a LaserActive super cheap. I discovered that a ic protector on the power supply was blown. I picked up a new one and she fired right up. This is where I ran into trouble... I popped in a laserdisc to test her out. Dancing in the rain played flawlessly for about 15 minutes. Right when I was about to shut her down and screw the cover back on I realized the sound was getting lower and lower. After about a minute the sound cut out entirely, then I noticed the video started to diverge and make 2 overlapping ghost images. after about 30 seconds of that, poof, no more image, and the distinct smell of too hot electronics... Now if I turn it on, everything acts like its working but theres no sound or video at all. I took the whole thing apart again to look for any obvious issues. The only thing I saw was, apparently, the audio demodulator ca0002am got hot enough to start melting the little plastic cover that lays over the video board. Does anyone have any experience working on laseractives that may have some guidance on where to start looking for faults?

no one?...
