Does anyone have a board diagram where the caps are that need to be replaced? I was able to replace all but one. I apparently dammaged the board & do not know where the contacts go. It's for the cap # CX250. If any one can help it would be greatly appreciated.

hi. you sure your replacement -- power supply & main board in good condition???? lcd present 5v , 12v, &24 v ??? if no you need going back power supply. if yes. you need to replace inverter board as possible. good luck!
When the DC filter caps no longer filter out high frequency AC, that AC will be fed through out the circuits and cause damages such as the inverter frequency will be running at the wrong frequency and caused overheating.
The service manual does not show the sch of the power supply/inverter board because it is not designed by Viewsonic. http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20VX924/
Its been a while since i worked on that power board. But I believe you are refering to the orange diode that runs into the single connector for the video board next to the power supply. I replaced mine with a 1n914 diode after replacing the 2200uf lytic cap and the tv fired right up.
There are 2 caps. One on the top and one on the bottom. First try bottom. Take all screws from the bottom cover, take bottom cover off and there will be board/flex with one cap on it. 1. Mark polarity (+ and - ) with marker. Unsolder cap. 2. Clean whole board with brush and alcohol VERY VERY good. 3. Solder new cap.
I have heard a lot in my years but never Condo not even from my Grandfather who was born in 1901, however back you your question, I have not seen Diagrams for the monitors those of us who are repairing these simply make note where the caps are that need to be replaced and then desolder them and install new caps at the same value as listed on the side of the cap we removed usually you don't need to do more than 6, most times its 1, I find and all is well again. I have never had an inverter fail it has always been the power board that has issues.
I use this monitor on my desktop system. A great monitor until it died with this same issue. I almost went out and bought a new one, but thought first I'd search Google to see if anyone else has experienced this. That is when I found this posting.
After opening the case and getting the printed circuit board out, I saw that the eight 470 mfd capacitors had slight bulges on the top. I went to Radio Shack. Bought 8 new cap for $1.19 each and a soldering iron and solder.
I'm not an experienced solder(er) so it took me about two hours to remove the old caps and replace the new ones and put the monitor back together.
VOILA!!! It works perfectly!
Thanks to all of you who took the time to post this.
