SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

SOURCE: vizio L42, wont turn on

Usually when this happens, the TV is in Protection Mode. When the TV detects something has gone wrong inside, the TV will prevent itself from turning ON.
Try leaving the TV unplugged for 30 -45 minutes so the TV can discharge and reset itself. If this doesn't fix the problem, most likely it's a power supply board related issue. At that point, you may want to get a price quote from a local TV repair shop. The cost of fixing the TV may exceed the price of a brand new TV.

I would guess the power supply went bad. The Vizio parts store sells the replacement for $82. Cheap fix for a decent TV.

Replacing it only requires a moderate mechanical skill. Removing the screws from the case is the hardest part. Remember to unplug the TV before you attempt this repair, or contact a local repair shop. They may only charge a small fee to install it for you.

The power supply may have failed, or it is in the safety shutdown mode due to short circuits in the power supply or in the backlight inverter board, you can try disconnecting the power cables to the backlight inverter board to see if you can get the TV to come on with sound but will not have picture.

Power Light comes on but no picture or sound.


for your VP50, it could just be simple as a power supply but it could also means more. Do you have the amber LED light when off and green when on? if so, try the main board first. If that doesn't resolve the problem, then change the sustainer boards.

replace the sustainer boards should correct this problem. New sustainer boards may cause red and green pixilation. If this happen, replace control board and TV is as good as new.

For the 42" plasma, you need to change your sustainer boards or your main board to fix the problem. If your TV is still under warranty, call 877-MY-VIZIO and they will have a technician go to your home and fix the problem for free.

For the L42 HDTV, you need to change the inverter boards or the main board. If your TV is still under warranty, call 877-MY-VIZIO and they will have a technician go to your home and fix the problem for free.
