Hi there WebRepOverall ratingThis site has no rating(not enough votes)

I am not sure when you posted this but I have the same model and reading the manual it seems to be the lamp. Please replace the lamp (check the lamp model on the outside of the TV on the right side facing the TV).

Hope this helps

Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...

SOURCE: LG 50px4dr plasma tv turns off immediately after

The problem could come from the power supply at the first suspected one. If you have a knowledge of trouble shooting, open the cover then examine if any caps there look poping up. Use your finger touch on the top of caps you will feel it. If not, check all the fuses there then disconnect all the cables from power sup to other boards, except the main board. Check Va and Vs according to the label attached on the back of panel. If the power sup shut down, replace it with a new one. Hope it helps.

This isn't an easy fix, it sounds like your power supply board is bad or there is a main board problem. I'd suspect a faulty power supply capacitor or heatsink missing, but you have to bring it in to a tech to know for sure.

five years is the life of many of these sets, the only parts sold are boards so I would guess main board but others are possible, I wonder if boards can even be found for a five year old LG?

I would replace the capacitors in the power supply if there are any dried up components and get it fixed before it fails completely and does serious damage.

I have no sound on two channels only

If you are in Australia and have no sound on GEM and 7-Mate, follow the instructions here, to update the TV's (LG 50PB4D-AA) firmware. Once done you will receive sound on these channels.

LG 71SA1D-AA TV turns off after about 5 mins now. It is about 3 yeARS OLD. cAN YOU TELL ME WHAT IS WRONG PLEASE.???

Well you most likely have a bad lamp; I say this with about 95% certainty. It is very common for a lamp that is getting weak to stay on for a little while then shut down, I see it all the time.

So what I would recommend you do is replace the lamp at this point.

Do you know how to do this by any chance? If you still have your owners manual there will be instructions in there on how to replace the lamp unit. If you do not have this I will assist you in getting it out.

Also you can purchase a new lamp many places online, also they will sell the lamp in two different ways, the first is just the bulb and the second is the bulb in a housing. If you get the whole thing in the housing (costs a little more) the job is a snap. If you get just the bulb then you will need to disassemble your housing, take out the old bulb and install the new one.

Note - There is no way to test the lamp. So i would advise to call a tech.He might charge $25 - $35 for the inspection, but would exclude all other problems before you spend a big chunk of money for the lamp.

Good Luck!!

Set turns itself on and off with no picture nor sound

You have a major problem with this set. Could be the main board, the Y-SUS board, or the power board or some combination of these.
