I got LG 29 INCHES FOUR YEARS BACK, NOW IT IS GIVING A PROBLEM WHEN I ON THE TV ITS OK BUT AFTER SEVERAL MINUTES THE PICTURE BECOMES GREEN AND PICTURE COMES LIKE NEGATIVE IN COLOURS. WHEN I SWITCH OFF


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Screen is all Green


New cable box recently? If not, your cable provider has probably pushed a firmware update to your cable box. Green screens are very common with HDMI connection. From your symptom, I am going to take a guess that you are connected via HDMI. If so, switch to Component cables and your problem is solved. It's not the TVs fault... cable boxes seem to be the single largest problem child for HDMI compatibility. I hope this was of some assistance.

LG Plasma Green Screen


First thing to do would be to check your cables feeding into the TV. If you're using component cables, it's likely that your red and blue cables have come unplugged and all you're feeding to the TV is the green signal. However, if you're using a different set of cables or they're all plugged in properly, I would first suggest swapping out the cable for a new one. In newer televisions, such as yours, each of the colours is transferred through separate channels regardless of the type of cable used.
If either of those don't help then I'm afraid you've got an issue with the charging of the phosphorus gas itself, either it's not receiving the power correctly or some of the gases are remaining inert and not charging. If you're at that stage, you need to seek technical assistance from a service depot or LG.
Best of luck!

You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..
