Re: Identifying blown caps

Quick update :

Put it all back together to identify where the sound was coming from ( like [B]selldoor[/B] suggested ), it was silent, plugged a HDMI in and it worked perfectly. Taking the whole screen apart and fiddling around has somehow fixed the issue.

Massive thanks for all helpful advice. As I went and brought a soldering iron kit just to do this I've decided I'm going to source a cheap broken LCD off ebay as a little project.

Cheers, C.Re: Identifying blown caps

Yes thats right, Its a Proview PV190WLCM.

I've got as far as the bulb ends, I'm not sure what I'm looking for at this point ( attached pictures ). Do I need to some how remove those silicone covers, seems like its going to be a real pain, was pulling at it for a bit but its glued in place.

Re: Identifying blown caps

Okay thanks for the information [B]selldoor[/B] and [B]mariushm[/B], I'm really hoping its not a bulb issue read it was a difficult fix. I'll study those lamp ends to check.

I'll give the cap replacement a shot too, out of curiosity more than anything.

Here are the front and back close ups of the power supply...Re: Identifying blown caps

Hi Guys,

I'm new to the world of caps and would appreciate a little first time advice.

I'm attempted to fix my LCD monitor. I've been having problems with it powering on, flickering and hissing then turning off 30 seconds later. After some reading around I've concluded its probably the caps on the power supply board. I've pulling it open and had a look at the PSB however they are not showing the obvious signs of being blown.

I was wondering if I could firstly get an expert eye to conclude if they are blown and secondly if indeed they are blown it would...
