Be sure the inverter is getting 24vdc at the input first. Could be the DC supply too the inverter.......

You will have to isolate the main board and Inverters.
Unplug the inverters and turn on the set.
If it "turns on" then try re-connecting each inverter seperately to see if only one is causing the problem.

Disconnect the slave. If the set operates replace it. If not the main is bad.

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.

No picture no sound just a black screen


I just repaired this LCD tv exact same model.
symptoms- when the tv turns on, all I get is a black screen with blinking green light. No other error codes. It was crazy frustrating trouble shooting this. I measured the transformers on the master and slave inverter board with a multi meter. The resistance should be 1.31 k ohms. All but one measured within the specs except one. I get an OL reading. I took a chance to order this part on eBay for 13 dollars. After soldering it, the resistance for all of the transformers were back to specs. The tv powered on and stayed on. Works good as new. If anyone has the this similar issue I would advice testing the mini transformers on your master and slave inverter board. My email is normanw1@yahoo.com for help.

That sounds like an inverter problem. Check the capacitors on the inverter boards. There will be two on each board. The master inverter will be on the far left side, and the slave will be on the far right side. You will have to remove the metal covers over the inverter boards. Should be 4 small phillips head screws. If the capacitors have bulging tops, replace them.

Check the capacitors on the master/slave inverter boards. I just repaired a Vizio VW42LHDTV10A with the same problem. Cost to repair $2. The master and slave inverter boards should be on the far left and far right sides of the TV set. They both have metal covers installed over them so you will have to remove the covers to access them. I'm willing to bet the tops of your capacitors are bulged.

Vo42l no picture. please help!


I had the same problem. No picture but sound. When I turned on the tv, and shined a flashlight around the screen from about 3 inches away, I could it was displaying something.

At first I replaced the main board which has 0171-2272-2604 stamped on it. You can google Vizio VO42L service manual and get a pdf which will show how to remove the back. I got the board from TSM www.tristatemodule.com3642-0482-0150 3642-0482-0150 Vizio TV Module, main unit, 0171-2272-2604, 3642-0482-0395, VO42LFHDTV10A 1 $88.95 $88.95

These are compatible replacement inverter boards and work well. All I had to do was bend a tab on the aluminum cover that goes over the boards. After installing these inverter boards the Vizio display works. I started with main board replacement because from what I read online, the problem was either the mainboard (which had the most posts) or the inverter boards. So I picked one.
Install tips:
Download the PDF Service Manual VO42L FHDTV10A_LPL,AUO Service Manual.pdf for some help with the back cover.
When you take all the screws out, set them aside in the same pattern they were on the board for ease of putting the back in.
I was not able to remove the connector on the Ribbon cable between the master and slave invertor, so I left it attached and carefully undid all the tape and removed the boards attached. I plan to send the old boards to Coppell TV (really nice to work with) for their re-use.
I hope this helps.

Picture goes out after about 10 minutes. Vizio L37HDTV10A


You need to open up the set and measure the DC voltage on the backlight inverter board to see if you have the 24vdc after the picture goes out, if you do have the 24vdc, then the problem is in the inverter board, if 24vdc is gone then it will be in the power supply. parts: http://www.shopjimmy.com/catalogsearch/result/index/?q=l37hdtv10a&limit=200
