Apparently these are an odd ball size or something, 2mm x 417mm, I suppose my micrometer may be a little off though because I can't find anything close to this length in 2mm. Closest thing I can find is 2.6mm! Think it would pose a problem if I use the 2.6mm It looks like I would have the room.

Re: Proview PL926Wbi 19" LCD no picture
LOL! Yeah it sucks when a bulb blows right in the middle of something.
Anyways my brother lives about 45 minutes away so I didn't go all the way over there just to take his monitor a part again, so I decided to do a visual on the backlights to see if I could see anything physical. The short answer is I would like to apologize for not heeding the advise of earlier posters that suggested the backlights being the problem. When I took the top light off they were actually burnt in off at one end the bottom ones while not as bad I could...Leave a comment:

Re: Proview PL926Wbi 19" LCD no picture
Again this is not likely to be a backlight problem as the monitor works for quite some time before losing it's pic. It appears as though it may be heat related, if someone has actually seen backlights fail in this way please feel free to post. I am gonna start looking into the vga board and see what I find there. If anyone knows what the likely cause is I would surely appreciate the 411.Leave a comment:

Re: Proview PL926Wbi 19" LCD no picture
I replaced the power/inverter board with a new one, and still same thing. Works fine for a while and then starts flickering and then shuts off. Turn it off and back on it stays on for a while and then the same thing. I took the new board over to my brothers as he has the same exact monitor and it works fine in his.Leave a comment:

Re: Proview PL926Wbi 19" LCD no picture
Well that didn't go well, now it powers up and just stays black screen. Any idea where I can buy a new invertor board?Leave a comment:

Re: Proview PL926Wbi 19" LCD no picture
I did measure them all to ensure I got the right sizes there was just a couple I couldn't find the exact right size for 220uf25v 8mm X 8mm to be exact. I just wanted make sure I could use the taller 8mm X 12mm in their place. there is plenty of room for these so I think I am safe.
I know I am asking alot of questions but I am what people would refer to is a perfectionist and I don't like making mistakes so hopefully you don't mind all the questions.
A couple of the caps were actually glued down one with...Leave a comment:

Re: Proview PL926Wbi 19" LCD no picture
Also I noticed that a couple of the smaller caps don't have vents but otherwise are identical in appearance. Name brands appear different as well NEC on the larger caps and Xunda on the smaller ones without vents. Would the smaller non-vented caps still be electrolytic or some other type of cap?Leave a comment:

Re: Proview PL926Wbi 19" LCD no picture
I ordered them so they should be here in a couple of days or so.
Does it matter on the overall height of the cap?
Example:
If the current cap is 220uf 25v 105c 8mm X 8mm
Would it be okay to us 220uf 25v 105c 8mm X 12mm
or does th height need to be the exact same?Leave a comment:

Re: Proview PL926Wbi 19" LCD no picture
Usaully I just buy kits of capacitors but I haven't been able to find any kits for this board. Any suggestions as to brand and series?
I need the following sizes.
470uf 25v 105c 10mm X 16mm
220uf 25v 105c 8mm X 12mm
47uf 50v 105c 6.3mm X 11mm
100uf 400v 105c 18mm X 32mm
220uf 25v 105c 8mm X 8mm
10uf 50v 105c 8mm X 5mm
Any advice is appreciated.
ThanksLeave a comment:

Re: Proview PL926Wbi 19" LCD no picture
I will just go a head and change the capacitors. As far solder fractures I don't see any would they be visible or is there another way to find them?
ThanksLeave a comment:

Re: Proview PL926Wbi 19" LCD no picture
Since the lights actually light up I wouldn't think it's the lights themselves. It seems like more of an inverter problem from what I have been able to find on the subject. I just can't find any obvious problems. I am hopeful that someone here may be a little more advanced than I am and can set me on the right path.

Proview PL926Wbi 19" LCD no picture
My Proview PL926Wbi 19" LCD will turn on and work fine for a wile and then starts flickering a bit until it loses it's picuture. After it loses the picture if you turn it off and then back on it will have a picture for about 3 seconds before losing it's picture again. Power light stays on solid at all times. I have checked the the inverter board and vga card and there are no signs of overheating, bulging/busted caps or solder fractures. Also when holding a bright light to the screen you can still see the image. I am kind of at a loss for what to do next. Any help would be much appreciate...
