Re: HP w2338h LCD Monitor randomly powers off and randomly won't power on.
You know, I honestly didn't even think to check the solder conns. I have ReFlowed so many xbox 360's and this didn't occur to me. Good idea. I will double check that stuff when I get a chance to. Thank you very much for the idea....

Re: HP w2338h LCD Monitor randomly powers off and randomly won't power on.
Woh. Went to Digikey. Little overwhelming on what they have available. However in their listing it states high quality Caps and notes the same names you mentioned. Here is the link.

I can't do the testing today due to some school things going on with my kids. Hopefully I can test and fix or order tomorrow.Re: HP w2338h LCD Monitor...

Re: HP w2338h LCD Monitor randomly powers off and randomly won't power on.
Thanks very much. I found a complete cap replacement kit on Ebay for 13. I'm going to hook everything up one more time and check for shorts while it's powered up. I found a black mark in the casing that looks like a short. SO I think selldoor was on to something when he talked about the safety being tripped. That really sounds like the behavior it was showing.
Course, your description is just as valid really. So, both will be tended to. I really appreciate the help guys.

Backs of the boards.
2088 is the logic board. 2089 is the power board....Last edited by cobaltsmith; 05-21-2012, 01:18 PM.

Re: HP w2338h LCD Monitor randomly powers off and randomly won't power on.
Amber? I'm honestly not entirely sure. I did the power tests some time ago and only recently pulled it back out to check for bad caps and what have you. I heard about some retarded power mode where it won't turn on. I made sure that wasn't the issue.

HP w2338h LCD Monitor randomly powers off and randomly won't power on.
Just started having problems with this monitor and not sure why. I have it taken apart and can't see any bad caps. I was hoping someone might have an eye for what's going on better than I.
I can turn it on and it will run fine for random amounts of time. From turning off immediately to waiting half hour. Sometimes it simply won't turn on. Any help would be greatly appreciated. Thank you in advance....

Re: Chi Mei iz3d Monitor Black out problems.
Oh, caps are in. Stupid question. How do I determine how to place them? One wire is longer than the other, however, how do I know how to place them in the board after I pull the old caps? Any suggestions? I'm assuming it has something to do with the orientation of the gold bar on the caps on the board and the same line on my new caps.

Chi Mei iz3d Monitor Black out problems.
I have a Chi Mei iZ3d 22" monitor that doesn't seem to want to display an image. The problem kinda came out of nowhere. The monitor was plugged in and on for about 2 mo. Then I took a trip for 3 days and turned my computer off for that time. When I came back and started up my computer and turned on the monitor there was no image but I could tell the backlight was on.
After unplugging the second input *the one needed for 3d* and pulling the power plug from the monitor several times, it displayed an image and began to work fine again. I had it on for another 2 weeks then took...Last edited by cobaltsmith; 04-24-2012, 02:10 PM.
