Re: very dark screen
Hi yes it looks like the inverter has failed and will need replacing, or if your compitent enough you can fix it at board level. The usual suspecs are a small SMD fuse on the inverter board / power supply board and/or buldging capacitors which look like blue or black cans.

Your windows 7 screen resolution is set too high and your display doesn't support it. There are 3 possible solutions to this problem: 1. Press F8 during startup and choose "Enable row-resolution video" 2. Press F8 during startup and choose "Safe mode" and change screen resolution there, then reboot. 3. You can always use another display (if you have one) to set screen resolution to lower value.
medproducts, Nothing new here. Check internal "switch-mode-power-supply board" only after devoting about 1-2 hours of viewing "lcd monitor disassembly" and "lcd monitor repair" video clips at YOUTUBE!!! Then you will need to make big decision!!! Let me and all who read this know what your plan of action is.
packldr, If your certain that the monitor is not going into sleep mode, you will need to find out where the possible bad solder joint might be. This type of symptom could be a "intermittant thermal fracture" of a solder joint on an internal printed circuit board inside your monitor. Your monitor works fine until the internal temperature rises enough to cause "thermal expansion" to cause a OPEN connection on some critical component on a "switch-mode-power-supply" or "cold-cathode-fluorescent-tube" power supply circuit. (INVERTER ckt) If you visit youtube, check for videos that deal with "LCD monitor repair" and "bad capacitors", "LCD disassembly" just so you know what you are dealing with. Please let me know if this was helpful to you. I'm louie12fix on fixya or firstname.lastname@example.org Bye for now.
you will need a card for your tv which is quite impossible for the average jo to fit in as has to go on the inside to allow you to use VGA? really sorry but nothing governing wether tv makers tell you about it or not?
Your site is extremely misleading and fraudulent. I was under the impression that I would at least get a hint at what might be a problem instead of you folks making me wait to get a money for something answer that you could have displayed on your main page. Places like yours have no place on the internet and I'm going to find out what I can do to report you.
