By nothing happening,do you mean that even the LED at the front does not come on? Did you check for shorts on the main audio/video board?

Thet are Metric screw M5 or M6 about 35cents at HD, Lowe's, ACE. The length can be figured out by using a small stick to find out how deep the holes are.

SOURCE: I have no picture but

Hi ,
Power on the unit in the dark room then aim a bright flashlight directly to the screen, you will barely see the images. This is because your backlight is not functioning. The following reason is the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

SOURCE: can i replace a vizio screen model #VO420E with a vizio screen model #VO42L FHDTV10A?

Hopefully you did not try to take the circuit board from the broken LCD and graft it onto the good one - the possibilities for problems are enormous.
Double-check all of the connectors, then compare the model numbers of the main board and power supply between the two sets. The cable between the LCD and the main board is often rather fussy and delicate - DO NOT pull on the wires! You may have to swap cables also. If the main board is different, try the one that went with the good panel (from the VO240E), and hope that part is good.
Note: electronics are susceptible to damage from static electricity. Handle the circuit boards only by the edges, and try to maintain contact with the metal shielding parts as much as possible (an anti-static wrist strap is a good means) while working on the set to discharge any static buildup on yourself.Once you are done, there is an e-Bay market for the remaining parts. If you have identified the bad board from the VO420E (by elimination), you can get more for the others, and you may still be able to sell the bad one to a reconditioning company, who will repair it and resell it.
The worst case situation is that the LCD panel driver board is bad, but as I understand your situation, the VO240E wouldn't turn on anymore. That is usually a power supply problem.

Found a Vizio VO42L By the dumpster and want to try and repair it. I plug it in and the orange logo lights up, press power and it turns on and the logo lights up white but picture flickers with horion

Sounds like it might be a solder joint. use the meter and check the ohms on each side of the solder joints on the board where the serial cables connect to the boards. it would be a good idea to check as many joints as you have time to. If it is a LED TV check Led control board for bad joints. if it uses Flourocarbon tubes check the transisters on each lighting control board. you may only have one board working causing partial back lighting.

Vizio vo42l fhdtv10a has no video with backlight on.

May or may not be worth fixing depending age and cost of set when new--if backlights on could be power supply (NEED TO CHECK all voltages out of power board) or even a main board etc---

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

Order Notes: None
$88.95 Shipping: USPS Priority $20.00 Tax:

$108.95 However, after I replaced this board I still had the same problem. So next I replaced the Invertor boards. There is a Master and a Slave board to the right and left sides of the main board. I ordered these from Coppell tv.
on Ebay.

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.

Vizio vo42lfdtv10a Turns on the vizio name light, goes from orang to white. In the back there is a blue light on left florescent driver board, It comes on for a few seconds and goes out. Florescent lamps...

I will check out the back lights inverter board first if there is any defective electrolytic capacitors or not, if not, the problem is the main board.
