Learn why your screen is blank and you have audio - No image LED TV Repair Review Main Board Problems ...
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
Hello,
If the screen went black and you can still see faint images of what your computer is currently showing, the typical issue would be a burnt out backlight. For the repair cost, I'd say just invest in a new monitor.
Just to cover the bases, make sure your brightness and contrast settings on the LCD are not set to zero.

Immirella, If you don't have extended warranty you will need to repair it yourself or contract out the work. This seems like (from your description
) that one or more of the units DC voltage sources on the "switch-mode-power-supply has failed and is now in partial shutdown mode. Yes, the unit still has operating voltage source for the digital, tuner, and audio circuits. You may or may not see an image on the screen if you hear audio and shine a very bright flashlight 1 inch from the lcd panel. You should pay a visit to YOUTUBE (just FYI) to check-out repair video clips of LCD monitors and LCD tv's. Your unit (FYI) is classed as BLACK SCREEN of DEATH. Same as any other brand of LCD monitor or tv. Call a local repair tech for more info. Good luck. 12fixlouie
lik2brew, Well here goes!! Your LCD panel, same as lcd panel in computer MONITOR, requires a little more than 120vac from the wall to create the cool, crisp, colorful images you see on the screen. It is my best GUESS, that your unit has a "FAILED" SMPS, or is "IN SHUTDOWN MODE" trying to save itself from having a catastrophic nonrecoverable event! e.g. sparks, smoke, fire. The SMART "switch-mode-power-supply" is designed to detect FAULTS with itself and other peripheral circuits. Your LCD TV is no different than the CLASSIC "BLACK-SCREEN of DEATH" that thousands of 14" to 32" LCD computer monitors suffer from!! Your set just has 2 more things to go wrong! A tuner, and audio processing circuits. While your waiting for the HOPS and BARLEY to ferment, surf over to YOUTUBE and view some of the longer video clips of typical "LCD monitor disassembly" and "LCD monitor repair" and find out what LCD owners do to fix them or to who they "farm out" the repair work to.!! If your screen had nice, bright, crisp, colorful images displayed on it just before the BSoD hit, then there is a good chance of effecting a lasting repair to the unit. If this was of some interest to you please rate on fixya. 12fixlouie
Look at the venting grill to see if you can see any whit lights inside behind the LCD panel, you may have to do this in the darken room, if you do see the light then at least the back light inverter is still working (inveter board failure is the common problem, same for the power supply, then the problem can be in the LCD driver board not working, or power supply is bad. Please post what you find.
The backlight drivers on your power supply board are out. If you check our web site at: www.ccl-la.com/badcaps.htm We have a step by step repair guide that should get you back going again.
I hope this helps, if so please rate our solution.
I see many monitor with that trouble.
When you turn on comp., you can have a picture on monitor about 10-30 min. and that go in black screen, or If you change resolution again go in black screen.
You must repair monitor or bay another.
Could be faulty graphics chip or faulty screen. If you can hook up external monitor and picture is fine then probably faulty screen. If external monitor shows same problem the faulty graphics chip. Take to repair shop and let them have a look.
Hello there. I understand that your Notebook is not showing the display lights. To isolate the issue please do the following troubleshooting steps.
1) Check the display with external monitor. If the external monitor is showing the display then the problem is with the LCD screen. If the external monitor is not showing the display then the problem is with the display card.
2) If you have any torch light or a cell phone , try focusing the light on the LCD screen after the Notebook is powered on and check whether you are able to see the texts and images on the LCD. If you are able to see the images and texts then it is the problem of the LCD back-lights. The lights which glow at the back of the LCD panel are not working.
If your Notebook is under warranty HP will repair it free of cost.
