Good day to you friend. in the beginning i would check the color transistors on the circuit board on the back of the crt neck. it has been a while since i have had to deal with these, but i believe it is supposed to be around 5v per transistor. if one of these are completely off in voltage from the other two then suspect that one to be at fault..if you are checking for resistance then you could do that also. make sure all power is off and the voltage has been drained from the set. check the caps by the color ic also with an esr, or use your ohmmeter.test your color ic for correct voltages that could cause erratic color problems. i personally believe that you are having problems with your green color amp on the back of your crt neck. it is gradually going out that is why it is turning a greenish color. thank you for reading and please rate my solution.

I replaced both backlight boards but still having problem with LCD TV...it is too dark and color distortion.


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

How do I know which part to replace in my LCD TV...is it the backlight or t-con or main board?


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.

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.

If the picture is washed out showing poor color it is the picture tube that is the problem, overtime the emission from the guns gradually declines until the picture balance is lost and it progressively gets worse. I recommend you replace it since repairs would involve a new picture tube and cost more than a new set.

It sounds like you might have a defective LCD panel. Your warranty for your TV is 18 months. Some of these models the warranty was mis-printed and said only 12 months.

Tv started to shut off here and there, then the


Hi,samsung has 3 major failures.The 1st one is the lamp, which averages 6000-8000 hrs 2-4 yrs.When it's about to go bad it shuts off and on or image won't come at all.You can find your part here:http://www.discount-merchant.com/SearchResults.asp?Search=BP9601472A Another problem that causes tv to shut off is the ballast,which is the board that powers the lamp.It makes clicking sounds and will cause pic to flicker.The other problem is the color wheel .The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.Have a bless one!

PANASONIC 36" TAU --- NEED HELP


Sounds terminal. Companies build things with "planned obsolescence" in mind. In other words. You buy a TV today, and the warranty says it's good for 4 years. 4 years and 3 months later, it dies.

I hope someone else can help you.
Good Luck!
