Clarification to my earlier post:http://blog.coppelltvrepair.com/2010/10/vertical-or-horizontal-color-lines-in.htmlHope this helps!

Might require looking inside at the inverter power supply. Most probably some capacitors in the power supply are leaky or dry. Else, the display itself has worn out.

Smell of Ozone comes from the anode cap of picture tube based TVs. If anode cap is firm and good, there will be no ozone smell at all.

that problem is on the y sustain board..just replace the y sustain to work your tv fine again..

This happened to me with a TOSHIBA Regza 42" flat panel. I spent $180 dollars to have the TV taken off the wall, transported to the authorized TV repair shop to have them tell me it only required a firmware update!I suggest you go to the LG support page, plug in your model # and instructions on updating firmware to that TV.Good luck!

Power supply filler capacitors may be your issue. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you save $300 least!

HelloTo repair Plasma TVs, whatever brand it may be, you must have thorugh knoledge in electronics, and experience in repairing Plasma TVs. you must have knoledge to follow its schematic diagram, which can be downloaded from LG website. The device is so compelx working principles, and working on it without any knowledge in electronics, will be risky for both health and exendature.It is best fro you to get this set repaired by the Authorised Service Center for LG at your town, or by any well experienced service technician, have work experience with plasma TVs. OK

HelloThere is some over current consumption when the set heats up. Just see whether its cooling fans are working well. It can't be predicted the fault, as it need a through check up.

HelloThe power supply board to your TV has the fault. Normally, these power supply boards have no repair, as components used will be very difficutlt to get from open market. Card base replacement is recomended. This is the picture of the power board to your tV. You can purchase it from the authorised service center for LG at your town. Actually the work is somehat skilled one, and you must have thorough knoledge in electronics to do this work. After power baord replacement, some adjustments may need to be done. OK.

how can i put on subtitle to read word on lg tv

Hello civilone,
The problem is from the convergence board of the television. That is why it is coming up with such strange pictures. You need to first run a check on all the capacitors on the main board, as well as the picture IC. Then you replace the convergence board.
Run a check on the lamp also, to see if it is due for replacement.Having done this, the television will be in good shape once again.
Would be glad to know if this information was helpful to you. All the best. Elect_Comp

The reasion your set is shutting off is because the power supply is dieding, and you need to replace the electrolytic caps on the power supply, or purchase a new one, go to www.partstore.com sand check to see if they have your power supply.

Very likely that one or more of the 3300μF (10v) capacitors in your power supply have failed and require replacement. If you're proficient with a soldering iron and other tools, it should be an easy fix -- less then $10.

I had this exact same problem recently (no video, only sound), and when it was happening, initially turning the unit off and back on resolved it. This subsequently (within a few days) developed into a problem where the TV wouldn't turn on at all (try to turn on and LED would turn green and relay would click, but a second later the LED would turn back red and another click would be heard). It would require 50-75 "power-on" attempts before the TV would stay on, and even if it did, sometimes there was no video. Finally (a few days after that), my wife heard a "pop" (she called it a mini-explosion) while the TV was on, and then she lost video/audio altogether. The TV wouldn't power on at all anymore -- it became stuck in a cycle where the relay would just click on and off until unplugged.

All of these could be traced back to some blown capacitors in the power supply module. On my 50PC5D, there were 6 caps, all 3300μF, 10V, 105°C. Five were clustered together, and one was on its own, but all 6 had split open at the top and leaked out electrolytic solution (fortunately due to location/orientation, no damage resulted within surrounding components). I replaced all 6, and now the TV is working like new again.

New capacitors at a local electronics supplier were about $1 apiece, so it was slightly more than $6 to replace them all. I would definitely recommend inspecting all caps in the power supply (there aren't that many... maybe a dozen or so)... if they're bulging even slightly, just replace them while everything is opened up.

I don't recommend buying a "repair kit" from eBay or the likes, since many of these contain insufficient parts and tend to be over-priced (e.g. I ordered a "kit" for my specific board for $25+S/H that included 4 caps, 2 FETs, and a fuse, but it would not have been sufficient by itself (needed 6 caps), plus the FETs and fuse were fine; in my case the TV died completely before the kit arrived in the mail, so I went about sourcing the parts locally). I thought I was taking the easy way by pre-ordering parts while the TV was still semi-working, since the TV was wall-mounted and I didn't want to take it down; however, I wish I had just pulled it and identified the parts needing replacement.

Good luck!

you use the red and white plugs. HOWEVER IF you ran the signal into the TV via HDMI, you will need to take the signal from the ports on the cable device (or other unit, like Blu Ray).

Hello,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this IC is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.

Hope this will help in solving the problem.......
