Hi, I have got 1 HP 1702 LCD monitor that it's LED doesnt light up.
So I suspect it's the power supply faulty.
I opened and find that no bulging capacitors.

Could someone tell me where has gone wrong?
Must check voltages to the logic board.

2949hs or 2494hs??!

Last few week, just did a 2494hs for a HWZ bro same symptom as yours. Power board (inverter transformer) faulty. If same then its repairable.. if CCFL bulb fault, then like not worth it..

u can pm me if u want to discuss..

Need to open up and physical check the power board. I suspect capacitor/s could be faulty.

Mine's a cosmetic issue, but bloody irritating. The Samsung 193P+ screen has terrible clouding that's very obvious in dark images, never had this problem before - only started developing slowly in the last few months and only noticed when it started becoming a obvious. Any suggestions for a fix?

Thanks for the quick reply bro!

Not sure if this makes any difference, but IIRC my panel's a MVA type. I paid a bomb for this thing when it first came out, and I'm hoping to restore it enough to be part of a future dual-monitor setup. Assuming I choose to get the panel replaced, what kind of costs do you think it will incur?

Thanks, will do. Though chances are their pricing will be exorbitant (I've asked quotation for repair of EOL products before), that's why I came to ask you Seriously though, googling for the specs/parts really didn't turn up much results... think you can help?

What are the causes of the clouding? Is preventive maintenance possible?

$1099, in 2005... s*** wow it's been 7 years already?! OK, I REALLY wanna get this thing fixed.

haha... maybe u can try this.. .. however, i will have no guarantee whether those sellers are selling working or non-defecting panels.. in other words.. buy it at your own risk la.. ..
