VO37L HDTV10A backlight on, get sound, no picture


TV sets that have been exposed to significant surges can have multiple boards that are damaged. If the backlights are indeed firing, and you get no picture, you may have a problem with the T-Con board, assuming the main board is working properly. This is exactly why I steer people away from repairing sets that have been hit with large surges. In most cases it will be cheaper to buy new sets vs. repair them.

Vizio vo37l backlight rapidly flickers when dynamic contrast tries to dim the display


I agree that the problem is most likely on the inverter board. I repaired a Vizio 42" LCD with the same problem, it was bad capacitors on both inverters. Cost $2 to repair. Take off the back cover to the set and check the capacitors on both boards. If they have bulging tops, that's your problem.

My Vizio VO37L dropped from a small height and now wont turn on


I would take a very close look with a flashlight first at the screen unit for any signs of cracks etc. The display panel is very fragile and if damaged this is fatal cost wise.

Since you may have nothing to lose I would open set up and have a good look inside for any signs of physical damage.

If you need to know the safe way to open let me know and I will explain.

Power light but nothing else on vizio vt470m?


Power board is of course most likely problem here and I presume you found no puffed up caps on the board.

My VO37L one day would just not turn on, No picture just black screen. power works, and powers up just no picture or sound?


I would have to say that you have bad capacitors in the power supply.Open the back of the TV,and look at the can shaped items called capacitors on the board with the power cord.If any of them have the tops,or bottoms bulged out,they need to be replaced.This should get it working again.I hope this helps.If you have any questions,please let me know.Thank You very much!

The LCD screen is dark with no sound or picture when turned on.


I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE:Look through the back vents for a white light to make sure the backlight still works. I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.
