SOURCE: LG 50PX4DR plasma tv

I had the same exact problem as posted above. My 50" LG plasma was out of warranty for 1 year! I called the LG executive call center, and they were very helpful. They offered to pay for the parts and labor. They recommended a few local repair shops, and they set everything up for me. The tech came out within 4 days with one part. The tech had to come out one more time the following week, since more parts were needed for the repair. The Y sustain board, along with 2 adjacent parts that are required to be replaced as a set, and the power supply had to be replaced (parts alone cost just over $900). TV is like new again; I'm very happy with how LG handled it, and made what could have been a bad experience a good one.

Lg LCD tv less than 2 yrs old has sound but no picture. What could be the problem? power supply, main board, etc??


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. 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 inverter board as card basis.

http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I recently purchased a 47"


Your TV has a light sensor that changes the brightness of the TV based on room brightness.


It's called an "Intelligent Sensor"

You can turn this off in your "Picture" settings.

Congrats on such a nice TV purchase.

If this was helpful, please rank me a 4.

In my experience, there will be damage to the main pcboard, usually under the transformer.

Red light flashing while green light stays on


I have the same TV, your projection bulb has quit/failed.

A loud pop was heard and the picture has gone followed by a red led fault light clicking on and off.

if your tv is less than 1 year old, and you registered it with Toshiba, you could qualify for a free replacement.

otherwise expect to pay 200.00 for a new bulb from Toshiba.

only good thing is you can replace it yourself, only tool needed is a phillips screwdriver.

you can check EbaY for prices less than 175.00 to 150.00
i am on my 3rd bulb within 4 years....

good luck!
