I have a Samsung LCD TV, model # LN40A450 with a PC input. I connected my Dell Vostro 1310 laptap to the PC input and I consistently get a "Mode Not Supported" message on the TV screen. Why? I had a different Dell laptop before my current one which worked fine. Does something need to be set in the controls of the Samsung?

The lcd screen is probably going bad.

Try to switch the video display from your laptop to the TV by holding down the blue function key by the space bar and depressing the key that has the blue CRT/LCD on it.

Might be:
- your power supply is dying
- corrupt boot files
- hard drive is dying.
Please list more symptoms

I will explain how to:

• Open the case of the LCD

basically in all LCD monitors have two circuit boards (power supply board and system board)

• After you open you will see the two boards are

• You see a board that has a socket for the power source. wrote that the board we're looking for (power supply board)

• Remove all cables connected to the board and take out the board. (get noted before you unplug it)
  

• Now you see it components on board, we looking for capacitor.(see picture below)

• Looking for damaged capacitors, physically you will see a capacitor on the top like a bloated (see picture below)

• Replace the damaged capacitor with the same value that you can see on the surface of the capacitor. (In this step you need any soldering tool)

My advice: replace capacitors with higher voltage, like 10V replace with 16V or 25V will be fine.

hi,
your lcd ip board (power board) capacitor had already exhusted.
got to replace the ip board.

check for led lights if they come on.
note down the lights.
If you are able to remove the connection of the lcd to the laptop do so for instruction refer to www.dellsupport.com click on manal

with the PC input or analog SVGA the only 16:9 resolution it supports is 1920x1080, which can be difficult for some older systems to handle. However, on HDMI it should support all the standard HD resolutions.
