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.

My sony wega kf-50we610 unlike every one else i have no problems with set turning on my problem is i cant watch anything do to the picture being distorted scrambled like i can see the menu options and...


It looks like the vidoe board but the fault can be also a distortion in the horizontal / vertical section. So check the PIN amp and related sections. What must be looked is of the HSTAT can be off set.
Deguass the set well to confirm if there is any possibility of a distortion of picture by a severe magnetic field.
Since there can many problems associated with a distorted picture but you can try and see these possibilites other than the Y amp processing. Hope my suggestions helps.

Can't see picture


Is the onscreen menu just as distorted and are the lines across it or behind it? The pop you heard may have been a capacitor and since the TV is still powering on, it's the probably the video controller board that is on it's way out. If the onscreen menu looks fine, you maybe having a problem with the input board only so try a DVD that uses a different input and if it's poor, I would say the TV needs to have the input/output board service. If the OSD is distorted as well then it's definitely the video controller board and service is likely required.
