Re: Mag LT916s Model 900p 19" LCD dropping like flies
Don't mean to be post whoring but can't edit my most recent message, anyways, can't order from digikey way too many options. I think I'll just stick to the 'shack or flebay.

Re: Mag LT916s Model 900p 19" LCD dropping like flies
LOL back from ebay and google, no such thing as a "cheap" ESR meter, what a noob I am...
Guys any difference between:
Ceramic
Electrolytic - Aluminum
Niobium Oxide
Poly Film
Tantalum
Thanks again!Last edited by phubar; 06-17-2008, 09:47 PM.Leave a comment:

Michael, RMPCTek in the third post said that he had to replace the 100uf caps, I would replace those first and see if that fixes your problem.
I think I'll try to get an ESR for cheap, ebay maybe.
Thanks a lot guys this thread only keeps getting better and better for the noobs like me....Leave a comment:

Also I just tested the monitor as suggested above and the green light stays on when the monitor goes blank, so it seems the problem is the inverter, would replacing the caps fix it?Leave a comment:

Well caps are cheap and it seems easy enough (I once replaced the caps in a motherboard, that was a bitch and it didn't work! lol), I see 11 caps 6 470uf, 3 220uf, 2 100uf, might as well replaced them all, because if I have to buy a tool worth $20 that I'll rarely use for anything else, plus the caps (at least $20), plus I'm getting some new soldering tools for about $30, might as well just get a new monitor and forget about the whole thing lol
Thanks again guys, y'll have been tons of help.

KS, the monitor consistently goes blank in around 15 minutes of use.
Good tip on watching the power led, I thought the light would stay on regardless and didn't even pay attention to it but that makes a lot of sense. Is the inverter circuitry clearly defined in the power supply board? (I'm guessing is located in the top part of the board).
How would I test the caps on these things?
would a regular digital multimeter do or do I need some special equipment?

Well I don't mean to be cocky by any means but I know how to do that (take it apart, desoldering old capacitors, solder new capacitors), I actually need more info or orientation regarding the required parts, diagnosing or determining the actual problem.
I think I'll just change all the capacitors (6 medium size and the smaller ones) if I don't get any input from this thread.
Is the inverter board in this monitor integrated with the power supply? or is the inverter board the board next to the...Leave a comment:

Re: Mag LT916s Model 900p 19" LCD dropping like flies
Boy am I glad I found this thread, I have two of these suckers with the same problem, screen goes blank after 15 minutes of use, unfortunately I don't have the savvy to diagnose what caps are bad and whatnot, would you guys mind telling what caps I should replace? also when getting the replacements are they low ESR or general purpose?
Thanks a lot!Leave a comment:
