Guys, Just check and see if any of the Program / Channel + or - buttons at the Front panel are Ok? If any one of them has been accidently pressed too hard, then it locks the button in a permanent ON position, and channels keep changing.

Try unplugging your TV for 8 hours and it comes back to normal. At least it did with mine.

The TV goes crazy and changes channels by itself!

try to interrupt it by pushing the channel in the opposite direction or tapping the channel up/down button with your finger.

Changes channel by its self it goes crazy

You have ONE of two possibilities....on the Front panel buttons, you MIGHT have a stuck button or leaky button....

I suspect that if ALL it does is change channels...it would be a channel UP or DOWN button stuck....yes, it can fire up the tv too....But it will dedicate itself to doing only ONE function.

IF you have multiple operations, like changing channels, menu appearing, volume changing....then the MOST likely problem is actually the microprocessor causing the problem....BUT it is STILL possible to have SEVERAL buttons stuck....rare, but possible.

And unfortunately unplugging it won't even help in any of these possibilities....

You have to start with pressing each and every button one at a time and see if the problem stops afterwards....

IF it doesn't, then the next step is to measure the resistance across each button....they should read Infinite ohms.

If any measure lower, the button should be removed and see if the TV acts normally...

IF the buttons are located on a separate board with a plug that can be disconnected, you can just disconnect that while it's acting up and see if the problem disappears.....

If it still misbehaves after this, you NEED to get it to a TV tech for further analysis with a scope.....

Vcr does not run

Try changing the channels on the VCR itself. If you can do that, then it would indicate a problem with the VCR's remote. If you are still unable to change channels on the VCR manually, it could indicate a circuitry problem, for which you will have to get the VCR serviced.

Stuck on channel 2, "No Signal" and snow

Two things may be at play here. The tv might be only programmed for reception on channel 2 and will need to be re programmed to receive other channels.
Also try some basic troubleshooting on the remotes. Start with the remote that came with the tv. Replace the batteries try the "MENU" button. If you can get into the menu try to "autoprogram" the TV

Kenwood VR-405

more info would be nice. If you're using optical, make sure its securely in both the tv and your vr-405 receiver. I have owned the vr-405 since 2000 and i just purchased a sony 32xbr6. HDMI into the TV, optical out to the receiver, it sounds amazing!

Lack key appear on my flat screen

Do you use the remote control or buttons on the tv itself? Many TVs have a child lock feature that will prevent operating the TV without the remote control. If you use the remote control you should be able to change chanels, and to disable the child lock from the menu.
