Re: Nady XA-300 Amplifier

I know I am bumping an old thread, but I have this exact amp and it worked fine but now goes into protect mode as soon as the power is turned on. The fans spin for about 2 seconds then powers down.

All Nady will say is that it is a bad relay and want 70 to fix it.

any idea from looking at the pictures above, where the protection circuit relay is? Nothing looks bad or out of place on mine at all.

I have randomly unplugged everything trying to nail down where the problem is but it just goes straight to protect....

Re: 2 Concertone 19"'s same problems

You know I was gonna ask myself that but being a rookie I didnt know.

I guess that makes sense. I tested the meter with known loose good caps and then those. I was more concerned with the snap on meter and not thinking.

Whoops.

Re: 2 Concertone 19"'s same problems

Ok, if you look at picture oo46 the 2 caps on that board are giving me readings in the 10 through 35 range, even though they are 470's, where the ones on the other board are giving within 25 +\- of the rating.

Hi all, learned to recap monitors from here and now have these 2 problems sitting out in the shop.

model Concertone FR LCD-200T

I work for an RV dealer and we replaced these two 19" LCD tv's under warranty but they didnt even want them back.

Problem seems like bad caps but I cant see one that really jumps out at me.

Power light comes on green for the 4 seconds then goes back to red. I see no activity on the screen, in the dark or with a flashlight.

I do see this rusty looking stuff but it looks like a cheap glue job....
