Troubleshooting, cant open my tv


Hi,
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.

I have a desktop monitor. Once i turn on the monitor it stays lit for 2 seconds then goes black. The light stay on. I then touch the power button on the monitor to turn it off. I then repress the power...


The inverter circuits or the power supply for the inverter circuits have failed due to bad caps, cold solder joints, shorted transistors.
See my pictures here: http://s807.photobucket.com/albums/yy352/budm/Dell%20E193FP/
If you do want to spend money on tools and troubleshoot it down to component level, you can replace the board, here:
