You either have a bad t-con board or the screen is bad. Check to make sure all the ribbon cables are seated fully and connected. Even replacement parts can be bad sometimes, new and used both.

SOURCE: My Phillips 47 LCD TV is loosing picture but is keeping sound.

Main board feeds the t con board. However try the flash light test on set because it might just be the inverter board that powers the backlighting.

SOURCE: If I have replaced the T-con board, the mainboard, and the board with the inputs, and my TV image is still not showing up, what should I do to fix the problem? Is it the LED driver?

Other than the PS you have replaced all save for the inverter board or as you call it led driver.

SOURCE: I can’t find the T con board on my Coby TFTV 4025 LCD tv. From what I can tell there is only the Mainboard, Powerboard and Inveterboard. Does anyone have any pictures of where this board is located?

Reason you can't find it is there isn't one, on some low end TV's like this one they build it into the panel board to save a buck or 2 so if the tcon has issues the set will need to be recycled

Why is my TV burning through T-Con boards? Ever time I replace one, it works for 2 hours and then I lose picture again. I've replaced 2 so far.

Hope the TV have problem with the either power board or the lcd panel. Try to check the power supply is its produce correct voltages mentioned on its connectors if you need help then check the video for that. if the power supply finds ok then you have problem with the lcd panel. In lcd panel there is a some ics which used as the driver of the pixels. the tcon sends data to these ics. and if any onf the ics draws more current from t con board then it can dame the t con. They are not replaceable one ,its integrated to the panel. if its faulty then you have to go for a new panel for that tv. And it would be a expensive repair.

Picture is sepia like(just terrible)

This can be caused by two things, the first thing to do is disconnect the LVDS cable from going from mainboard to T-Con board the small board in the top middle of tv with a metal plate over it.
Clean the contacts of the cable and reattached the cable.
If picture still the same the T-Con board needs to be replaced.
In case of T-con Board replacement also check the power supply for bulging capacators because they can be the cause that the T-con board died.

My hisense 50 inch lcd tv has picture but no sound.

If you still have back light, then the T-con is probably defective. If you don't have back light, then you either have a bad power board/inverter or a defective panel
