Red or green tint on LG LCD 32" TV

Hello experts;

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?

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, 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.

Red tint on the screen an picture

Make sure the signal cable for the input you are using is tight. Possibly try a different cable. Especially if you are using the Red Green Blue component cables. Make sure the issue is across all inputs. If so, try adjusting settings for tint. if that doesn't help you may need to replace the TV.

Contrast really dark but seems to improve after the tv has been on several hours

You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

The T-CON (Timing Control) board on the panel is/has failed. If it is available, it can be replaced. If not, the entire panel will need to be replaced to correct the TV.

Hello! I bought a LG 32-inch LCD (32 inch )

My best advice would be to call out your LG service repair engineer, it is most likely the current software in the TV is of an older version & will need to be re-programmed which an engineer should be able to check. This should cure the menu problem.

LG 42 LCD no sound or picture

Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.

Here are the settings:

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.
