Power failures can cause all types of problems, have you firstly checked the fuse in the mains plug? If that is ok then it may have blown an internal fuse in the power supply board, these are there to protect the rest of the circuit from power surges.

How to fix a lg tv 47inch with black screen no pictur 47LB5900 model


The red light merely indicates power is getting to your TV. There may be an open internal fuse or power supply failure.

Medion lcd hd 31.5 inch tv won't turn on


I bought one also from ALDI for my son's Xbox 360, it is only 3 weeks in use and I have the same problem. The red led is on, indicating that it is in standby mode and recieving power but I can't turn it on either by pressing the power on button on the TV it's self or the on button on the remote. This started happening a few days ago and it's totally random. I found that if you unplug the TV from the power point or alternatively switch off the power point for a minute, than power it on again it will "WORK AGAIN" for a while. Like I said it is random, eventually it will return to the not being able to be switched on state at which time you will have to repeat the process. So thus, this is not really a solution. I am about to return the TV for a refund, and it's a shame because otherwise it's not too bad. and looks OK too.

Unplug it for about an hour to let it reset itself and try again, if it still has problem then you will have to open it up or take it to the repair shop. The power supply module will have to be looked at first to make sure all the voltages are present. Right now the 5vdc standby power supply is working and may be partially function processor.

37'' LG lcd tv, no power


I just want to clear things here.
The stand by light will remain on whenever the tv set is turned on by a button on the side of the tv.

Then use your remote to turn on the tv, but wait as it can take 10secs before you get a picture.

If everything else on the remote works, most likely the PWR function on the remote is not working.

This may be a problem with the conductive rubber membrane under the button, or the matracy circuit is not reading the function due to any number of problems.

You can call the manufacture parts rep to see if it is possible to have parts for the remote. Most of the time, they are not worth to service, and parts are not sold to support remote control service. You will most likely have to order a new remote from the manufacture rep.

I suggest to NOT buy a universal remote. They rarely can do more than the most basic functions. Many times universal remotes have different issues with different models of sets.
