Question about Insignia Televison & Video

Open Question

I have a 50" LED Insignia tv. The picture keeps going out but still has sound. I've replaced all 3 of the boards in the TV, and it solved the problem for another year. Backlights/LED light strips?

SOURCE: LCD TV Has Sound, Backlights Work, but No Picture

I have been having the same problem with my LG. people say there are bad capacitors on the power supply board. I don't have the know how to replace them and don't have the money to pay. I can get mine to work by blowing hot air with a hair dryer into the back of my tv through the vents over the board. Heat it up for a couple minutes and turn it off and then back on and the picture comes back. I just never turn the set off now.

The display panel should be suspected. The picture you attached here looks so. Contact the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

SOURCE: Jimmy shop.ccom has T-con board part #T500HVD0.0 500t10-C02 at the bottom in the description it list model PLDED5030A CRk my model is PLDED5066A-E since the parts # the same will it work in my tv?

If you see an image with a flashlight the T con board and power supply board are good. The back light controller board is the culprit.

SOURCE: On my Hisense 50K23DG LED TV, I have sound but no picture.

Hi,
Hisense TV's usually use PCB Boards by Vestel and not Hisense themselves, have a look at: Vestel Help If the Boards in your Hisense match this Board/Part Number format at least you'll know what to search for, replacing the power supply will not help unless the process has been incorporated into the power supply and that is not known for certain yet
Good Hunting

I have a 50 inch Toshiba 50L4300U that has no picture but has sound. What board do I replace?


Do this test first. With the TV on normally, shine a flashlight on the screen. look for a dim moving picture.
1) If you see one, the backlight led driver isn't working.
2) If you DON'T see a picture replace the T-Con board.
