Weird TV behaviour

Richard53

Still working fine, and now I am sure I have cured the fault. I find it quite strange that a fault developed in a component that was inside the TV casing, never touched or moved, and with no connection to the outside except for some buttons that were never pressed, and yet the remote, which is dropped, sat on, played with by the cat etc. works fine. I would expect it to be the other way round.


I found the Youtube clip through a Google search (the uploader's name was 'alwaysafix') and from the comments below the video it seems to be quite a common problem. Lots of "hey man this worked for me too, thanks a million!"


I am at work at the moment, but will post the TV model number when I get home.

TV model is Samsung LE32B530P7W.

For the record, the fix was:

• Unplug the TV from the mains supply and disconnect all cables to other devices
• Lay the TV on its front, with suitable protection for the screen
• Take out all the screws around the edges of the back (Phillips heads)
• (There is also one screw on the panel with all the connectors, with an arrow pointing to it)
• Take the back off carefully (if it resists, check you haven't missed a screw somewhere)
• Don't touch any capacitors etc, as these can hold a healthy charge even when the TV is off
• Find the cable going to the button panel (bottom left as you are looking at it)
• Disconnect the cable from the panel - it's a simple clip connector
• Tuck the cable away somewhere where it can't touch anything important
• Reassembly is the reverse of removal, etc.

Took me about 10 minutes altogether. Hope this helps someone.

Wouldn't hurt to save up for a new one - just in case.

Just for the record - a week later, and all is well. There must have been a fault in the button panel.

If the fix I did hadn't worked, my next move would have been to buy a new one. Not very MSE, but my TV requirements are very modest indeed, and something that would satisfy my requirements would probably only cost me about £150. The TV is at least 5 years old, so that's only £30 a year. If the fix can make it last another year or two, all well and good.

Electronic components can fail at any time in their life, and although those buttons were never used you can guarantee that panel was always live in order to provide power to the logic circuitry that is on it.

I'm with Gillor on this one that a component on that board is probably on it's way out, and as a result it now sends out random spurious signals which the TV is interpreting as user input and reacting accordingly.

Strange coincidence but my Sony tv did something very similar the other day. At first I thought it was ir interference but I took all the remotes out of the room and it still happened. In the end I tried retuning the stations and that seemed to fox it. Perhaps the recent changes to the channel listing was confusing the software.
