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.
Take it to a repair shop.
To use your LCD TV as a monitor. look for a HDMI output on the computer and the TV. If you dont have a HDMI output on the computer, you will need to spend approx. $70 for video card and install it. I found "VisionTek Radeon HD 4350" to work fantastic.. Make sure your LCD TV has a HDMI INPUT. If not, you will need a newer TV. All thats needed now is a HDMI CABLE. The cable can be purchased anywhere computers are sold for between approx. $30 to $40. Depending on length. The cables can be found for much less ON-LINE. firefold.com has the cables for approx. $5. and they are the high quality gold plated cables. Now plug the cable into the computer and the TV and then using your tv remote, switch to HDMI and your tv is now a computer monitor. "Note"you may have to make adjustment on computer for display size and quality. My LCD TV is a 46" and the video card described above supports HD full screen. A wireless mouse and key board are a nice feature to add. If you like movies, you can get netflix and stream movies. there are many other sites for streaming and downloading. after doing this with my computer, i dont have a cable bill any more..I hope this tip helps.
The only thing that comes to mind, as you haven't said if you have had it working on it or not, is the fact that it is not capable of handling the resolution you have got set on your computer. to fix this set your computer to a low resolution, connect to your TV and see if it works. If it does increase your resolution setting until it stops working. (if you get it wrong it will revert to the setting before). Hope this helps.
The first thing you can try is, connect the LCD Tv to another computer with the HDMI cable and verify it's working that way on the other pc. If it works, then the HDMI port on the Laptop might have a problem which will require Service. Troubleshooting and TIY will not fix the issue.
If the same LCD TV doesn't work on another computer, then double-check the cable and the connection. You'll be able to narrow down to the culprit and may need another LCT TV.
Is the LCD TV still working with other connections? like with your DVD Player or Cable.
Is it a monitor or TV???
If its an LCD computer monitor check your cabeling, the sound coard should be plugged into the "green" jack in the back of your computer. Check the "sound and audio devices" in the control panel if it is on MUTE or turned down very low.
If its an LCD TV check your audio inputs with another device to see if they work. Check to see if it has been muted on the TV. Otherwise its probally your main board in your tv buring out.
