Hello:
Your most likely cause to the color flash on your screen is a bad LCD panel. One way to troubleshoot this is to hook an externa monitor up to your laptop, and observe the display on the external monitor. If it is ok, then your LCD is the cause. If you still experience the flash, you could have a motherboard video problem, but unlikely.
There is no easy fix to get rid of the flashing line. If your laptop is still under warranty, or even close, I would contact HP /Compaq customer support and explain your laptop's problem.
Hope this helps !

Hi,
Generally the problem is caused due bad LCD inverter cable. Kindly run the LCD diagnostics
How to Run diagnostics
1. Shut down the computer
2. Disconnect the AC adapter and Battery
3. Press the power button for 10 sec.
4. reconnect both AC adapter and battery
5. Press FN key+ power button

If the LCD problem is shown in diagnostics your screen would have to be replaced.

Ds lite flashes on but fuses are ok


One or both your screens have blown.

Try removing the motherboard from the screens and attach the battery the green light should turn on and stay on.

Now attach the lower screen and turn on. If the screen is ok the screen and green light will flash and then turn off. (if the screen doesn't flash the bottom screen is you're problem and will have to be replaced)

If this happens the problem is then you're top screen which you will have to replace.

Press power button green light comes on.But no picture no sound,


I have had my WS-65511 fail like this, first at 4 years, second 2 weeks later, then 3rd time yesterday (4/14/2009). In past, the tech replaced a thermal sensor p/n 299P313010A (but Mitsubishi says that part is not for WS-65511 and that it does not have a thermal sensor - go figure). It is a white rectangle with about 30 pins in 2 rows and is soldered onto a board in the TV. List price is about $25. Might be your problem.
