I have a 52" Mitsubishi Lt-52244 TV which has sound, no picture but has images with the flashlight test. Which board/s should I replace?

SOURCE: how munch would it cost to fix my Mitsubishi TV -

Depends on the damage, your problem is vaque.

Best Buy, Radioshack both send off items for repair.

Find a local tv shop, if they fix it for less than $200 i'd be surprised.

depending on damage location, and severity i estimate $200-$800

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.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

SOURCE: TV Samsung 50 UN50EH5300FXZA BJ04. Sound but no picture. Replaced all boards, still no picture. Flashlight test saw image.

Hi Rick,
It appears to be a case of backlight failure. since you have replaced all the boards, inverter is ruled out. Some of the LEDs in the backlight array may have gone bad. Fault is repairable, but needs care and experience of opening and repairing the LED panel. Good luck.
