Pentranic 1125 CGA 26" no video and chirp noise

[violentsnake]

I'm very new to all this and bought an MVS cabinet off of someone on
craigslist. Everything was fine until I wondered why the marquee didn't
light up. SO, I took off the screws and no bulbs. I put in two home
light bulbs and they worked fine.

The problem though, the monitor went out. Even after taking out the
bulbs I get no video at all. What I do get in it's place is a frequent
chirping/clicking noise going about every half second perfectly
consistent.

SO, I definately did the dumbest thing I could've done and just put in
bulbs without researching the right bulbs (100W btw) What I'm wondering now, just
how bad of a problem do I have on my hands and suggestions for
repairing it? As I'm very new any help in the right direction would be
a great help.

I could buy a new chassis (found one on ebay) but don't want it to go out again if there's a problem somewhere else as like I said, putting in new bulbs in the marquee is what killed my monitor. It was working literally like 5 mins before the bulbs went in.

First picture is my cabinet, second is the manual it came with, third is NOT my actual board but a picture of a similiar one.

Big thanks to anyone with the patience to help me out.


I'm going to assume the best thing to do is get a multimeter and check all the caps? All the fuses are visibly fine too btw, I was praying this was just a bad fuse. Are those cheap multimeters that ship out of china on ebay ok to use?

Thanks again

It was working literally like 5 mins before the bulbs went in.

absolute coincidence.

these chassis are quite old. likely the capacitors are going to need to be replaced. it's not uncommon for a monitor to work for 2 mins then die.

what you are hearing is the power supply of the monitor board turning on, getting overloaded, then shutting down. over, and over, and over, and over, and over, and over, and over,.........

give this a try. plug it in... wait 10 seconds, then unplug it (or switch it off) and plug it back in (or switch it on) again after a (one) (1) second. if it fires up you have a power supply start problem that is easily fixed. if not, you may have something a little more involved going on.

do you have a volt meter you can use/borrow/steal/buy to do some testing with??
