I have prodipe powered monitor speakers. one of

I have prodipe powered monitor speakers. One of them works fine for 10 minutes or so and then starts crackling. Let it cool down and it works for 10 minutes and starts again. Seems heat related like a component is breaking down. Cant see any dry joints. Any assistance would be appreciated

It will be a semi-conductor that's causing the problem. All you need to do is get a can of Servisol Freezer Spray. Then when it's playing up spray any of the semi-conductors you suspect (one at a time) with it. If it's the faulty one it should start working. To confirm it, heat it up by touching a leg or pin (IC) with a hot soldering iron to get it to act up and spray again.

We have a Viewsonic Optiquest Q9B-2 LCD monitor with built in speakers. Worked fine and all of a sudden wouldn't power on. We checked power cords and changed 3-470 caps, 1-330 cap, and 1-10 cap. Monitor...

Probably not yet. Check and replace the power transistor on the source board , it has been surely fried when the capacitors failed. If even after that the source doesn't start then the transformer has been fried.- you will have to replace the entire power board. This will cost you around $75. If you think your monitor is worth that much money then go ahead, replace the board.
If not...

It will be an IC or transitors that is faulty. You can get it to act up quicker and find the faulty part faster by getting a freezer spray for electronics. All you have to do is wait for it to act up then blast each suspected part with the spray. If it stops acting up you will have found it. But to be certain, warm it up again with a soldering iron and then blast it again.
Don't spray everything, just pick on one at a time!

No sound from monitor speakers. Worked fine for 5 years. Can hear sounds when using headphones plugged into CPU. Hope you can help even if only to tell me I need a new monitor. Sincerely Dizzyme.

First of all, check if your audio cable are still plugged into the monitor and pc output (light green) audio jack. If not just plugged it back in... Still still got no sound... Then turned off the monitor and pc. Unplugged all the cables from the monitor and pc, wait for 10 second till all the surged built up are cleared out. Then you can plugged all the cables back Monitor should have 3 cables, a audio cable, a VGA or DVI cables, and a power cord... OK! now you got all the cables plugged back in...
Turned on the monitor and PC....and a few should hear window started. Still... had a problems....just get a external speakers. Have nice day!

PF790 monitor picture issue

Was it dropped? If so, it could be a board crack or damage to the CRT. Was it stored in an unheated garage, shed, or attic, etc.? Damp air or widely changing temperatures can cause condensation on the circuit boards. Minerals and other impurities can collect on the board via the condensation, leading to some nasty corrosion. Plus in my opinion, late-model CRT monitors are a real pain to work on. Many of them have so many shields and so many screws that before you get the board free to work on it, you're sick of messing with it! *grin* Then when you do some work on it and want to test it, you have to do a lot of reassembly first. I'm sure others will be tempted to jump in here and tell me how crazy I am, but unless they belong to a family member, I don't even work on them any more. When it comes to monitors, I only work on the flat-panel types. But if you go for it, look for electrolytic capacitors with bulging tops or leaking bottoms, bad board connections, etc. Good luck!
