When I turn on my vizio tv it does not have a picture but has sound. sometimes I can turn it off then back on and I will show a picture, or if I let it warm up for about a hour. what could the problem be?


Easy fix! Shop Jimmy may have the inverter board you need. If you know someone with electronics experience show them this info. Before you purchase the inverter board, have someone pull the back cover off and locate the board. I would check the center screw, and try to tighten this a little bit. I have seen this TV not have a good ground on the inverter board and will not light up. If this does not work, order the inverter board. Please check part numbers to be correct. Thanks for asking me.

I have a Vizio VF550XVT1A. First problem was a flickering screen that ended with the TV turning off. I replaced both invertor boards and the TV seemed to work fine for a few weeks. Now the TV works fine...


Good day sir Alfred!!!!

If your screen turns to back after a minutes but the sounds is normal..That problem is very common to all flat panel specially to LCD TV..

OK,I need to know first if your TV having a back-light when the picture went out after a minutes.If that so the possible problem is T-CON board (this board is the responsible to produce a video on all LCD TV)..

If you don't have back-light the problem is inverter board again..But before you order or install new inverter board try to find why the inverter board gone only on few weeks after you install it..the possible problem why the inverter board faulty for the short period of time is higher/lower input voltages (24vdc) comes from power supply..try to check it using volt meter or multimeter tester..it should be read 24vdc on meter..let me know if the voltage drop or higher to 24..

If the 24vdc is fine the only problem is the condition of inverter board maybe its used or partially faulty when you buy it..

if you have more queries and clarification regarding my solution please feel free to reply on this tread...

Hope it helps..

Thanks for using fixya..

Tv would not come on..sound then came on.. 1 hr later picture


That sounds like a faulty inverter board.

The inverter board is the high voltage board that supplies power to the back light lamps.

The inverter must be tested and eventually replaced.

Vizio GV42L LCD TV screen black when turn TV on first time


If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
