Vizio VW42L HDTV10A No Picture or Sound

While it is unfortunate that you had a bad experience with your Vizio LCD I can honestly say that I have great luck with my Vizio LCD 46" over 2.5 years old.I also have 3 other Vizio LCD's that I have had no issues with.

Hi all,
I'm glad I found this thread. I too have a Vizio 42" which recently took a crap. After Vizio refused any kind of assistance in its repair other then to say it would cost around $600.00, I took it upon myself to fix it (I hope).

My question to anyone is how to remove the cover to get at the main board. The last thing i want to do is make things worse.

I've removed all the screws and mounting brackets from the back of the tv. and tried lifting it off but its not coming. Any Help would be of great assistance.

P.S. I got my mainboard from Encompus (800-432-8542) They sell brand new (not referbished) boards. Its where Vizio gets their parts. It cost me $123.90 + $20 core.

Thanks in advance....

Hi Again,

After replacing the Main Board I'm still sitting in the same boat. I can hear the TV and change the channel but NO Picture! Any Ideas??

Panel/inverters

Which inverter (Master/Slave) and is there a way to test them?

Has anyone out there fixed their TV's? I'm now looking for someone who
has a TV like mine. Hopefully we can work together to figure out which
component it is that is bad in your TV and mine, by swapping parts and
trial and error... Once we know which parts are bad then we can proceed
to find said parts. Until then we can guess all we want.

I've already swapped a new Main board into my unit and discovered that mine would seem to be good and make me believe it is one of the inverters.
Oh ya, I've found out that the Inverters for this model are non existant.

If you have a VW42L FHDTV Please reply. I believe the inverters are used in another model as well.

Master Inverter part number; 6632L-0470A PNL-T707A
Slave Inverter part number; 6632L-0471A PNL-T707A

Wow - this website is great.

I didn't want to make a new thread about this model so I thought I'd add to it.

About a week and a half ago my 1.5 year old V42L started having the No Picture w/ audio issue. Luckily, I purchased my TV from Wal-Mart with the 3 year extended warranty. The service center was fairly prompt in contacting me back and setting up an appointment.

Service man gets here Friday and after checking voltages, etc decides that the LCD is bad and is preventing the inverters from firing the backlight (I think that is what he said). He put in an order to replace the LG LCD through his company.

Here is my question - he mentioned that a lot of the time warranty companies can't find the LCD for TVs like this and will just cut a check for replacement. How likely is that scenario? The original purchase price was 900+ so would an LCD be more than the cost of the set? What is the time frame I'm looking at?

Thanks for anyone's help!
