Question about Samsung PN42A400 42 in. Plasma TV

2 Answers

I cannot adjust the volume on my Samsung 42" Plasma (PN42a400)

As a matter of fact, all of a sudden, I can't control anything on my TV. The only button that seems to work right now is the big power button on the front. I've unplugged the TV for several minutes and that didn't seem to fix it. I've taken the batteries out of the remote and tried using the controls on the side of the TV, that didn't work.

This TV is only 4 months old. It's under warranty, which is great, but it seems to me that this should be a fairly easy problem to fix.

The fact that it turns on is good. Most likely the trouble is with a data line internal in the set. It may be the remote receiver IC or a push button on the set. A stuck button or switch can confuse or load communication between internal microprocessor circuits. Take a look or feel each of the push buttons do they feel the same when pushed ? Do they have a slight snap when pushed. The tac switches used in most cases are made like a small old clicker. If one feels soft and has no snap it's probably your trouble. If so tap lightly around but not on the button and it might free itself. You should just have Samsung replace whatever is the cause.

I have a 42" Samsung


This clacking and clicking noise could have been coming from a capacitor going bad in the tv. If this is the case where the tv will not turn back on, I would suggest calling samsung to try to get a replacement or get the tv serviced. Trying to replace bad capacitors can be a tedious job and requires knowledge of soldering small components. This may also void your warranty if you still have coverage.

My tv enlarges the picture cutting off peoples heads on the screen


First go to your source such as your Cable Box or Sat Box. The problem is that the Aspect ratio is set incorrectly on the source or the tv.
