Vizio VW46LFHDTV10A Really dark picture.

[Bafury]

Gentlemen!! I am at your mercy...please take a look at the pictures i have taken. When you first power on the tv, there is a little thin vertical line further to the right side of the screen, but goes away after tv heats up. I am new to this, and i need to know where to start. Can somebody help me? There is no blown capacitors..and there is light coming from the screen..I have sound, and i can use the remote

thank you for all the help

With your hand if you tap around the front of the LCD frame do you see a change in picture quality/brightness?

[Bafury]

Re: Vizio VW46LFHDTV10A Really dark picture.

No..there is not change..I even tapped on each of the ribbons connected to the t-con board, and there was no change.

Hi Bafury, I'm here!
He called me earlier in the day and I mentioned this forum for him.
Unfortunately, my TV looked totaly different then yours.
On mine I had only on side of the TV darker and it had ghosting going on, but all the colors were right. Yours has something else.
You are in good hands here. Good luck with this TV and with the others, that you have.

Re: Vizio VW46LFHDTV10A Really dark picture.

I had a sony with a bad panel that was made by AU Optronics. Before i scrapped the panel i was tinkering around with it and i noticed there was a little hole on the top of the panel with a "pot" screw. Since i was junking the panel i started turning it to see what it did. It actually made the screen go lighter and darker. So if your panel is by the same maker it might be worthwhile to take a look and see if you have the same "pot" on the top of the panel. I even think there was a hole in the case for acess to it. Worth a look before you part the tv out.

Re: Vizio VW46LFHDTV10A Really dark picture.

Is it even worth it to buy a replacement panel? Where can i buy a panel...Can the panel be fixed?

[tibimakai]

Re: Vizio VW46LFHDTV10A Really dark picture.

it's not worth it.

Re: Vizio VW46LFHDTV10A Really dark picture.

one more question....by any chance...could the cable that connects the t-con board and the main board cause this if it was faulty?

thanks

May be the cable, cleaning and reseating is always worth a try.
Did you find the pot screw?
Could be voltage regulators on the tcon?
We can help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

thank you selldoor
I have no idea what the pot screw looks like..Please check back for my post as i will have the pictures you request..

Re: Vizio VW46LFHDTV10A Really dark picture.

Did you try a replacement tcon board? I got a tv on sunday that had an almost negative display. It looked real similar to your photo with the xbox360 dashboard. I told the guy it COULD be the panel but we can try a tcon. We looked up a tcon and it was $20 shipped from ebay. The guy was willing to roll the dice and see if it worked.

Got the tcon board today and sure enough it fixed the display. If you haven't made any head way on your issue and if a tcon is reasonably cheap, it may be worth giving it a shot.

If you take the front bezel off or loose enough to see the metal surrounding the LCD screen, on the flat top section there will be a hole and you can see that it will take a flat blade screwdriver inside the hole.

It was very white. You could sorta make out the images on a cable show but it was very fuzzy and grainy. I'll take a picture with the old tcon before i put the tv back together.

Re: Vizio VW46LFHDTV10A Really dark picture.

Bafury has dark screen, not white. It may have different issue.
I played ones with a 52 Samsung and I cut some tab traces by mistake and it was very white, but still a clear picture.
