The power supply will need to be replaced. This is the box that connects to the plug-in wire.
If you can get a soldering Iron, then you can solder off the old joints, find the number written on the power supply and Go to
Philips
.PartStore.com
or
www.MCMElectronics.com
or
stores.shop.ebay.com/LCDPAYLESS__W0QQ_armrsZ1QQ_fsubZ3123744
($30)
or more if you google philips magnavox power supply.


MARK ALL WIRES WITH COLORED TAPE SO YOU KNOW WHICH ONES WENT WHERE!
Then simply resolder new joints and wires.

My 55inch LG 3D smart tv is not working properly. When you turn the tv on the LG home screen comes on for a few seconds, and then the screen goes black. What is causing this


it's set to the wrong input device ? the one you currently have it pointed to has no input

also it's possible that cable plugged into current input channel has gone bad or become disconnected from it's source
Hdmi cables are unfortunately famous for this as they have no Lock device to keep them inserted into ports

most TV's nowdays shut off if not provided an input for a few minutes

Keeps turning off saying protection


It could be possible your tv volume is too high and the speakers are ment to take in a low volume level and amplifiy the signal themselves. That or there is an electrical malfunction with the device.

The red color does'not work, the screen appear green only


Unfortunately, it's not possible to give you any advice about where to start trying to repair this problem on your own. Missing colors on a TV can be caused by many things: simple bad solder connections, component failures, or a bad picture tube. Without the necessary test equipment and service information, it's nearly impossible to fix many troubles.

The only suggestion I can make is to take this set to a service shop (or call for home service if it's too large to carry) and get a repair estimate if you really want to keep the TV. Or use this as an excuse to replace the set. Especially if the tube is bad, repairs may be uneconomical.

I wish I could offer more help. Good luck and thanks for using Fixya~

Tv won't turn on, keeps flashing red, will not turn a solid color


Sounds like the lamp needs to be replaced.

Before any repair or replacement, unplug the tv from the electricity for an hour, plug it in. This forces a system reset on the tv and may solve the problem. More likely you need a new lamp.
