Question about LG Flat Panel Televisions
Bought a LG LCD flat screen 32" TV just over a year ago ( I complained to LG and Best Buy. No help. Warranty is expired.)
While watching, everything will all of a sudden turn shades of red or green. Green or red men playing football. More frequently now as time goes on. This is very annoying.
Is it simple to diagnose and change out a lamp or assembly board or something?
SOURCE: power indicator is flashing
Possible error on JB board - diodes D5701, D5703, D9616. Replacing them should be sufficient. Anyway, you should contact the nearest Sony Service. Regards, Arpi

Bad caps in the power supply. Replace all bad cap or replace Power Supply Module. If you choose to try and fix it yourself yourself will need a ESR Meter to check the caps in circuit. Let me know if this helps.

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
hope this helps...

It can be either the T-CON board or worst case will be the LCD panel. Check some voltages on the T-CON board to make sure it has good clean 12vdc feeding it.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

SOURCE: screen keeps turning green
I had the same problem...turned it on and everything was a shade of sickly green, and no amount of colour adjust could get it back. I checked the forums and discovered that rather than the plasma tv, it could be a problem with the cable box. I checked other inputs, such as HDMI and my DVD hookup, and sure enough, the colour was fine (other than the residual tweaking I had done to repair it before). Problem solved, call the cable company (and save the expense of a repair or a new TV. Called the cable company and they suggested that I twist the connector cables between the box and the TV. This I did and it is as if it never had a problem in the first place.
All this to say, if you have this problem, try to check all the hardware connections first, before assuming that the TV is on the fritz.
I'm very relieved, that's for sure.
