VIZIO VO42L FHDTV10A:stand-by light (orange), power light (white) both work, but no image. I bought a replacement master inverter card and installed it. nothing changed. I have attached a few pictures of my power supply. I do not know the name of the part shown, but there is a bump on each one. Can someone tell me if I need a new power supply. Thank you.

Those are dipped polyester capacitors.
With lights out & curtains closed, does the screen glow at all?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

thanks for the suggestion. with the room void of most light, with the power on (white vizio lcd light on) the screen does not glow at all. i think i wil have to buy a voltage meter to check the power output of the power supply. will post the results soon. thank you

Re: Vizio vo42l fhdtv10a - No image
I think you need to do some voltage testing first , also look real close at both inverter board to see if the IC controller has blown, very common to this model.

The inverter boards should be changed in pair and also need to see if they need modification.Attached FilesNever stop learning

Re: Vizio vo42l fhdtv10a - No image
I had the same problem with my Vizio VO42L. Audio but no picture. After reading threads in this forum I turned on the TV, shined a flashlight about 2 inches from the screen and could see it was displaying "No Signal". I then picked one of the two main options to fix it. I replaced the main board which did not solve the problem, then I replaced the Master and Slave inverter boards and the TV now works again. I purchased the replacement inverter boards (two long boards on either side with a long ribbon cable attaching them) from coppelltvrepair on ebay for $49. 6632L-0470A & 6632L-0471A INVERTER REPLACEMENT SET - NEW, OEM, WARRANTY
Item# 110882329800 $49.99 USD 1 $49.99 USD.
I purchased the main board from Tristatemodule . com for $89. 3642-0482-0150 3642-0482-0150 Vizio TV Module, main unit, 0171-2272-2604, 3642-0482-0395, VO42LFHDTV10A 1 $88.95 $88.95
Also, note that the inverter board set from coppell tv are not original but substitutes that work fine. the configuration is a little different and all you have to do is bend a flap on the cover that goes over the board to get the cover to fit (coppell tells you this on the website too). I recommend coppell tv .
I suspect my original main board may still be good. If anyone would like it and the old inverter boards (for parts maybe) you can have them for the cost of the postage. Just let me know at jjfiorello-triffids @ yahoo . com

Re: Vizio vo42l fhdtv10a - No image
I just fixed this model with bad inverter boards. I found a set from 12 boxes of crap I bought for $80. The boards do not mount up the same, but I could get one screw in each and fit the wires. I took some scrap alum. and drilled holes to mount them. Tv works great. Its been 3 weeks since repair.
