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.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

SOURCE: Same Insignia problem but still not working

Check if there is back light on or not?
If back light is on means this unit is having problem with panel (deffective.).
If there is no back light change main baord.

Good luck

I think you need to exchange the Main Board.

SOURCE: Samsung PS42C7S Power Board

A blinking led does point to a bad power supply board! First, Look for some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain).

You should be able to find a service manual @ www.manualzone.com

Buying a power board try www.shopjimmy.com or ebay!

Good luck, hope this is helpful!!!

Do flashlight test to see if y0ou can see an image - if so replace the inverter board that powers backlights. If no image then go for the main board.

If you see a picture with the flashlight you can rule out the T-Con board. It's working. So the led driver board is the problem. TV Parts Universal TV Stands DLP Chips ShopJimmy Go here for replacement parts.

No picture sound ok rca 46la45rq


Sounds like backlight is dead. Shine flashlight on screen. Can you see video slightly. Replace inverter or some sets have inverter as part of power board. If led set replace led driver board. Also that may be part of power board.
