Samsung LE32C450E1W

[bernardporritt]

I have a Samsung LE32C450E1W
Changes channels and volume on its own, the power indicator LED is flashing fast all the time and the remote has no effect whatsoever so cannot turn it off only at the socket, if you place a finger on the touch pad and keep it there, it will stop it changing channels.
I fitted a P-Touch Key PCB part number BN96-13046D 4 months age to cure the fault which it did. I now have the same fault back so I sent for another one from the same firm only this did not cure it as I still had the same fault. Thinking it was a faulty board I contacted the supply to request an exchange, but they will not.
So I have brought another from a different company and this one still does the same, so I guess it must be something else but what.
Could anyone help, any advice much appreciated.

Hi I think the fault will be with the board or the connection to the main board, you can check the lead and plugs with a meter, have you tried removing the batteries from the remote? But my bet is with a faulty touch board you only have to look on ebay to see one seller has sold 89 of the things,I have replaced four this year on C450 models from 26"LCD to 42" plasmas all ways the same fault volume up and down, changing channels on its own.

As I said in my post I have fitted two new ones of these touch boards only both have the same fault as the one they were replacing, yes I have tried removing the batteries from the remote, holding down one of the buttons for 20 sec then fitting the batteries back no change. Could I have got two new faulty boards from two different suppliers?
Thank you flocko for you reply

what I was trying to say is by removing the batteries from the remote and just using the touch buttons you are taking away the chance that the remote is faulty, I would not be surprised if you are getting faulty boards , if he has sold 89 new replacement boards that's 89 old faulty boards out in ebay land, and some seller will sell them as good

I can stop it changes channels by keeping my finger on the touch pad but as soon as I take my finger away its of again.

Both of the boards I brought were new and not from eBay but shops on line, one was from were I had brought one four months before and that was ok then, But this one did not solve it so I went to a Samsung dealer also a shop on line and asked if it was a genuine Samsung part and was told that it was. But that one also did not cure problem.

I found a suggestion on the web to cut the four wires on the right side of the lead (this one has 8 wires) that runs from the P-Touch Key PCB to the larger PCB this would allow you to still turn the TV on & off but would not be able to use the touch pad on the front and only use the remote but that did not work either.

Thanks to you both for your suggestions and help
