I have a Vizio VX42LHDTV10a To fix screen that
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. 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.

SAMSUNG TV WONT TURN ON JUST CLICKS
I just fixed this very same problem. The capacitors are
the problem. However, I think that if you have some minimal skills with
soldering, you can fix this yourself. You just need to take out the
system board, then the power supply parts are on the top right. The bad
capacitor(s) will be bulging at the top and possibly have some brown
stuff coming out. The ones that go bad are 1000microfarad, 10V, however
you can replace them with higher voltage. I got 35V caps from radio
shack for 1.59 each. You just need to solder out the bad ones and then
put the new ones in and solder. Remember that the negative end goes on
the side with the bold black part of the circle on the system board.
Then just cut off the extra ends of the capacitors. If you are capable
of doing this yourself, you will spend at most 6 dollars instead of
however much a technician costs.

Samsung 40inch LCD tv doesn't turn on for some
To all who are having power supply issues: Samsung is now acknowledging
a problem with the faulty capacitors. I called 1 800 726-7864 and they
said they would repair certain out-of-warranty TVs if the problem is
related to the capacitors. I just called and they are sending a service
rep out to diagnose the problem

Most probably the TCON board in your tv is defective. Please consult some qualified service technician. Most of the time the company service centers ask you to replace the entire LCD panel, which is an expensive affair. TCON board is a small part of the panel. and its job is to distribute the picture information across the LCD screen. Good luck.
