hiiiiiiiiii Akshay Ji

Seems to be na ic problem

the Y-SUS BOARD is for picture in tv.if the picture is not coming or not proper the Y-SUS board needs replacing .but if the picture is blurry or with linings reparing helps.but in your case the tv does not turns on with y-sus board connected only error led comes on.this means y-sus board needs replacement.
you can get it from www.partstore.com

if you are not familiar with replacing the y-sus board its advisable to get it done by local tv repair technician familiar with your brand/model.

Sounds like your convergence circuit went out. It lines up the red,green and blue picture tubes so the colors are lined up. Usually these TVs all use the same type of IC chips called "STKs" both usually get replaced along with any resistors etc.. around these chips that may have burned up. Depending on who fixes it could be around $300-400 parts and labor.

i am pretty sure u need to go to the menu and check your v chip or a button on the tv that starts with the letter v that will control the picture

you have a convergence ampliphier ic failing that will need to be changed and then adjusted
average repair cost for this are 280.00 to 320.00

you will need to have someone come out and reconverge the tv for you. it shouldnt cost alot but its what you will need to do unless you can do it youself.

stk392-110 i think mine was made in 2002 and i also had to replace mine

Stk392-110 red convergence IC is bad...normal procedure===

1) pull chassis   2) replace both Stk's for reliable repair

3)re-assemble  4) re-align convergence

 

If you hire a technician, 400.00 is ave. price.
