LG tv 32LB5600-UZ red light Black screen tried to replace power supply same problem

SOURCE: Plasma TV

did you hear the sounds? or maybe you have defective power source in hot side..

SOURCE: xbox 360 red lights power supply light stays yellow

you have to disconnect and reconnect the power cables to the 360. Orange/yellow light means that your power supply is on a standby mode and the 360 is not getting enough power/electricity inside

SOURCE: LG 26lx1d tv will not turn on. Power supply is

Have an LG26Lx1D for about 3 years, dropped off by my son.(Figures).Power light just blinking, but went back to red.Removed back panel, and metal cover. Just above antenna/cable input, its a small fan,mine was full of dirt. Blow off dirt, and make sure its turning freely.
Install back the covers, an voila....its a miracle...its working again.
Good luck

Sounds like a failed power board inside the TV, not the power supply. Unfortunately this is a very difficult repair, and unless you are an electrician I would not recommend attempting it. You will need to contact a local TV repair person in your area. If you think it may still be under warranty please contact the manufacturer to file an RMA. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.

So sorry that I don't have better news but it is definitely a power issue internally.

Thanks
