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

If your TV is less then a year old, still under manufacturers warranty. If not under warranty the defective parts could be the power supply or the back light inverter board. Both boards can be replace easily.
The way to know if you have a defective backlight inverter is by shinning a light from a flash light near the screen with the TV on and check in a 45 degrees angle if you have a dark video in the background, if the video is present then you have a backlight board failure. If no video, then is a power supply failure.
I have both boards if you want to buy them.
Let me know if you require further assistance.

the pic attached is an electrolytic capacitor, they come in different sizes and are usually blue, black and sometimes yellow. depending on manufacture.

most of the problems I have heard of tvs having problems with the electrolytic capacitors going bad. if you open the tv and see one of those swollen or leaking you need to replace them.

I suspect that your supply has gone bad. You will need to find the service manual for voltage measurements. If you want to get replacement boards many can be found on ebay or you can check www.shopjimmy.com they stock boards for many units and I have had no problems.

You do not need to buy anything, just look at the owner manual, or look at yor remote control for the button with 'DISPLAY', 'ASPECT', 'ZOOM' for adjusting the aspect ratio.

Any one of the TV's circuit boards may be at fault here, a repair manual and testing are needed to figure out which circuit board is at fault.

I have an insignia 46" tv I replaced the main board, the tv works except the picture is upside down, what will correct this problem


Flip the TV over! Just kidding!! When you installed the main board was it identical to the old main board? If so, you might want to look at the old board and ensure there are no jumpers that needed to be set on the new board. Some companies make generic control boards for tvs but have different jumper settings for different models. The jumpers are just little black blocks that connect different pins to each other on top of the circuit board.

At least the 5VDC stand by power supply is working, there will be a control signal pin from the mainboard to the power supply board to turn on the rest of the power supplies (24vdc for the back light inverter boards, 12vdc for other circuits). Any bulging caps in the power supply?
