Red and green colors not coming through in picture
I just purchased this lightly used TV from my best friend and upon set up it still has a great, crisp picture, however reds and greens both show up as a brownish color in the picture. What is my next step?

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 . 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. http://electro-medical.blogspot.com/
It sounds like the common problem with this set. It is an intermittant picture tube, or there is a loose connection on the green drive board on the green picture tube. Try lightly tapping all around on the green drive board while the set is on and see if you have any change. BUT BE VERY CAREFUL! Lots of high voltage on the board. Also use a plastic or wooden device to do the tapping. If you do great, you know you need to resolder the connections on the board or clean the CRT socket on the green drive board. If there is no change, I would bet the green CRT is on its way out. But try tapping the green drive board all over as I said before, that is a very very common fault with these types of TV sets. Good Luck
Go to your On Screen Menu to picture settings and reset and choose "reset picture" mode. This will bring you back to factory defaults. If this doesn't work shut off wait 10 sec. and turn on the TV. If still no luck call your best friend who is a TV repairman, you probably have a damaged blue drive.
the problem is at the crt base .there r three red,blue n green o/put.verify if there is dry in the soldering n check the red cathode voltage it must b around 150 .if not then check the resistor that feeds the red o/put.it could b 12 to 15k.
all crt have 3 driver color red blue n green,whenever one driver not working the color changes.that wat happened to ur tv
now i do not know wat model u have.the drivers may b transistors or now its ic that r being used like tda 6103q.best of luck
