TV stopped working samsung model UA32D5000PM

Check and replace its main system control memory IC. Before replacing it, just make a hard reset to this set. Unplug the TV from AC mains wall outlet, and re-plug it back after 1 minute or so. This must make the set a hard reset.

Our Sony tv is acting up....first it had no sound....then wouldn't change no sound or picture and turns off right after you turn it on?

I feel your sony is going to need another power supply in it or have the power suppply reworked. You might have bad eletrolytic capacitors in it that is causing this issue. That is what it sounds like when you said first the sound did not work then the remote did not work until total failure.

You might want to take that down to the tv repair shop and have them look at the power supply.

thanks and please do leave postive feedback and ratings for your free answer today.

I have a sanyo tv. Slightly older. Not hi-def or New

This may be due to the possiblity that the you are on the wrong input source, If you watch HD Channels then the input source would either be componet or HDMI input. Try changing the input source of the television with the TV's remote until you see the Channels again. IF you are not watching HDTV then the television is on the wrong reception channel for the Direct TV's box. Try channel 4 or 3 or even 73.

TV channel sound from a different channel

I just unplugged the tv from the power source and disconnected the cable connection and then reconnected them back after sometime. The TV started auto programming after turning on and that resolved the problem.

My tv is locked

They have an internal battery for transport between rooms so as not to lose any pre-programed channels or info while unplugged. So to beat this you will have to unplug it for a few days and let it clear its memory. Mine needed almost a week but when its turned on after the right amount of time it will ask to do a channel search. So make sure you have it hooked up to cable before running that search or you will have to repeat the previous steps. Hope this helps.

TV Changes Channels by itself

The keyboard switches are going bad part# 432P109010 (there are ten of them).To verify this, disconnect the connecting wire to the keyboard pc board and see if you still have the problem- the remote will still function normal- the green power led will not light up when you power on the TV with it disconnected so listen for the click and wait for the TV to power up when you use the remote.

Scrolling Channels

You probably have a bad channel down switch on the TV. This is common if any kind of liquid spilled inside of the TV near the controls. The other possibility is just a stuck button on the control pad itself. Sometimes the plastic warps a bit causing to rub against the cabinet causing it to stick. Try moving the button and see if it has free movement.
