Flicking chanels by itself

You most likely have a ccfl in the backlight that has burnt out. It's a long, thin fragile light behind the screen. I had a 40in sony lcd that I fixed this way.

Follow these steps to resolve your problem:

1. Turn off the PS3 so it only shows a red light. You can hold the power button on the front until it goes into standby. To be sure, flick the power switch on the back of the Play Station 3 off and then back on.

2. Make sure your Play Station 3 is connected to your regular TV (not HDTV) with the standard video cables.

3. Press and hold the power button until the screen "flickers" and then immediately release. This should reset the video settings.

4. Wait a few seconds, and the Play Station 3 (PS3) logo should appear.

If this does not resolve the problem, follow these steps:

1. Turn off the PS3 so it only shows a red light. You can hold the power button on the front until it goes into standby. To be sure, flick the power switch on the back of the Play Station 3 off and then back on.

2. Make sure your Play Station 3 is connected to your regular TV (not HDTV) with the standard video cables.

3. Press and hold the power button on the front until the Play Station 3 beeps and then turns off again. This should reset the video for you and you can turn it back on after this.

When you attach your Play Station 3 to an HD TV through an HDMI port, the Play Station 3 will ask you if you wish to switch to HD Mode.

However, if you decide to move it to another TV that is not HD compatible, you will get no picture because the Play Station 3 is “stuck” in HD (HDMI) mode.

That’s it! You can play your Play Station 3 again!

I turned the TV off. I held in all of the (4) buttons on the front of the TV and turned the TV back on again....this seemed to free up the remote control access and I was able to work the TV normally. The four buttons were the channel and the volume controls.

I managed to find a local repair man who fixed the problem. He put in a new transformer.

NAD Technical Bulletin T743-H2005-06 describes the problem "Unit may shut down, shortly after turn on".  Reason: There is a diode on the standby board that maybe operating intermittently.  Solution: Locate and identify D756 on the standby board.  Change only if the diode is a 1N4148.  Change from a 1N4148 to a 1N4004 or equivalent.  
It is located near a transformer and some fuses.

set is going into shutdown. what type of tv is this. lcd.. could be one of many problems.
