SOURCE: My LG Flat Screen won't turn on.

power board issue or capacitors on the power board have blown this happens with electronics, service center will be required to replace the board or if you know some one who solders electronics they could do it also. to keep this from happening again buy a ups backup power supply which will condition the power to the tv and other components and save you allot of time and trouble later.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

The solution for the problem is to replace the control PCB. The PCB is the printed circuit board that controls the volume, channel and menu buttons.

These parts can be found and bought from Sears parts direct.

Red flashing light on 47lg50


After use Tv will not turn on


Tv will not turn on after previously being use. We will use the tv for a period of time turn it off and come back to it later in the day or night and the tv will not power on. The flashing red light on the bottom right corner will flash but it will not kick over to the blue light as it does when the tv is acting normal. Now we will wait an hour or two and the tv will turn on and work but it just starts the cycle all over again. The tv is not hot or warm or anything and does not make a noise. What can I do to fix this?

47LG50 won't turn on, no standby light at all. DEAD! tried different power sources, but nothing. was on, made a "bzzzddd" noise then turned off. Serious or just a fuse?


you can remove the fuse and check them with a multimeter. put a lead on each end If the meter shows a low number (normally less than 1), then the fuse should be okay. if not than you need a new power supply board. be sure at all times to have tv un pluged while working on them and always be very cautious as the do still hold power. hope this helps

The power lights flashes three times and the TV doesn't work


Three times flash to LG TVs denotes a fault with its main board. Contact any service technician. If you're sound in electronics, check this link. http://electronicshelponline.blogspot.com/ Blinking codes to many brand TVs are given in detail. Pull up older posts there, either by its left side bar, or see it in Timslide option.
