My Vizio 55XVT1A power on, has sound, but no picture. I changed new power board, main board, T-cond board, but it still same problem. What's wrong with it? Is it anything with inverter board? Than



Answers :

If this is an LCD tv the backlight inverter is bad, a good way to check it is to shine a flashlight close to the screen and see if you can see a faint picture.

I have an ELCHS321. My backlight started to flicker. The inverter board is JLS-05-32EI. I have the back open and noticed that the LED on the inverter board was blue and flickering as well. As the set warms up the LED turns white but still flickers. The LED goes solid white and the flickering stops. Is this caused by the inverter board or or the backlight. Is there anyway to load the inverter board output to isolate th problem.


I would suspect and check first the voltages going there to see if low when cold and come up and if they are moving up and down when it flickers----points to problem in power supply ... Element ELC-HS321 32 in. LCD TV

I got a Sony Bravia KDL-40WL135. Blank screen. There's two LED lights: red standby and green power light. When I turn on the TV, green led comes on, then after about 30 seconds red led blinks once, then green resumes. The green led stays solid. I think that's a SONY error code, I tried to look it up but can't find anything useful. I have replaced the power supply, AU board, backlight inverter, logical board, and the second power supply board. Any suggestions? I haven't checked the t-con bo

Dynex 47 My Dynex TV stopped powering on. I was told it could be the power supply board cause the indicator light was not on red or turning green when you tried to turn the TV on. I installed a new power supply board, and i'm still not getting any picture or light indicator. What else could the problem be?


This is exactly why I tell people that when your set isn't working, you have to have it properly diagnosed. Chances are you have a defective main board. The power indication is an indication that you have standby power. However, the power indicator i ... Flat Panel Televisions

I own a DYNEX DXLCD37-09. I am having trouble turning it on. The red "STAND BY" indicator is on and when I press the power button the green "POWER ON" indicator flashes a few times and then instantaneously turns off. My question being, is the problem the power supply board or the inverter board?


It can be related to a power supply fault , problem in the SMPS unit. Also a poor connection due to dry soldering of the drivers cannot be ruled out and so if you tap the TV while it is powering and if the power comes up it can be a poor connection. ... Dynex DX-LCD37 TV

I have a vizio vz37l tv. When i turn it on the screen lights up, however there is no picture on the screen. the sound works, its just no picture on the screen. I read on a couple of the posts on here, and figured the proper course would be to replace the t-con board. I just finished replacing the tcon board and still the same thing. I called vizio about the problem and they say that if the screen lights up then the problem wouldn't be the backlight inverter boards, that it might be as simpl
