Replace the power supply board as card basis. It will be best, rather than making "Surgery' to it, and to waste time and money. It can be bought from the authorized service center for LG. After replacement, certain adjustments should be done. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

SOURCE: my 37 in lcd lg flat screen just keeps clicking on

Something is stopping the relays from starting up the TV. This will be a fault either in the power supply board or the microprocessor ICs or with the inverter board. This would need to be taken to a service repairer to diagnose the problem.

SOURCE: 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.

SOURCE: 37" LG flat screen is

With the onset of more and more TVs being hooked up to cable, TV manufacturers didn't need to make the tuners as sensitive because the signal from the Cable Co. was much stronger than the over the air signal. If the other TVs are older they may be just sensitive enough to lock onto the channel signals. You could ask your cable provider to check your available signal in the house to see if there is the proper amount of signal. Some channels can inherently be stronger and when "block converted" (put where the cable company wants the channels) all come thru but some are a bit clearer.

Have the power supply checked out. I've worked on your particular model with the same problem. Turned out to be bad capacitors in the power supply.

The bad or bulged electrolytic caps need change out on the power supply module, or just replace power supply. Go to www.partstore.com to purchase a new power supply.

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. Look for 5vdc, 12vdc, and 24dvc.

37" LCD Flat screen


Yes it could and most likely is the power supply board. If you look at the capacitors on the board you may see some that appear swelled or puffed up at the top. If you see any that are puffed up they are leaky and replacing them may fix the problem. Some times if the Inverter board is bad it will not let the TV come on. a LED will be blinking. If you have no power at all it is most likely the power supply.
