Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

Sometimes, TVs will switch to a new input when they sense a new signal on the new input. So if you're watching TV and someone turns on the AV device (or makes a change that alters or starts a video signal), the TV may switch over to that signal. This is a function of the TV. Some TVs allow you to disable this function, others do not. I looked in the manual and didn't notice where this could be enabled or disabled. If you want to only watch one source, make sure the other sources are turned off.

look for function on remote or an inbound arrow icon and square or tv/av button and press it till u see av 1 or av 2 or dvd and u are ready to watch video via your samsung hmoe theater

not drain check drain tube if you know who to make U trap do it will be ok

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

It sounds like since you need to try resetting the video settings. When switching between HDMI and AV or changing TVs, you can get a blank screen. Try these steps to reset it:
1. Make sure console is turned off completely(red light in front should not be on)
2. Hold down power button and then turn on back power switch.
3. Listen for first beep
4. Listen for second beep
5. After you hear the second beep let go
The screen should appear. And remember, this will have to be done anytime you change TVs or change between HDMI and AV. Hope this was the problem and that it helps.

Your ps3 could be in component mode. You will have to hook it back up on component mode, and go to the ps3 menu and change the setting to hdmi.

hmmm

i think you must save that in service mode.if not you must find a service

I have the same problem. I brought a Samsung 46" in July 07 and on Jan 8, 2008, video went blue.

I called Samsung and sent out technician and they replaced the motherboard.

Two hours later, same problem occured. I called today and Electronic Company thinks I have a bad LCD panel.
