Question about Vizio Televison & Video
I have replaced the power board, main board, and LED strips on a Vizio E550I-A0. The back lights come on but there is no image. I am working on it for a friend who said there was a loud pop before the image went out. Any advice or help is greatly appreciated

SOURCE: Loud Pop Vizio P50HDTV10A 50 in.
Just to add to the above post it can also be popped Ceramic fuses. Its worth a try. In most sets I fixed there are about 6 of them and cost you about 10$. Check the specs on the fuses and get the same ones. Pop the old ones out and the new ones in and see if it works.. If it doesn't you have to get a new PS board as WeListen2You has suggested.

SOURCE: So my vizio led picture went out. There were no back lights but you could still see picture on the tv if you shine a flash light at the tv. I replace my power supply board But it didn't work. Help!!!!
The backlighting has failed. If it is an older fluorescent bulb type you most likely need an inverter board.

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.
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.
