Vizio VT - Popular Questions, Answers, Tips & Manuals

I'd go with a power board for starters, are the other voltages ok on the power board or are they all low

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Check the contacts for channel and volume on the remotes.

where is channel set up

Sounds like a main board issue. Beware, some Vizio main boards can be hard to find and expensive !!!

I would suspect the main board as well

Check your manual and see whether these are supported.

There is no cheap boards. A particular model or TV will have the same type of board, and cost for it will be almost same to all spare part sites.

Visit the site named 'Electro-help' for more details. Click this link. View it in 'Flip card' option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. Some times, the ads attached with each posts, both at the right and bottom, might help you to find the availability of spare parts. There are more than 850 posts to different brand TVs now.

Im having similar problem and with my limited knowledge of lcd tvs and the voltages ALL being good except the pwr on or sw on voltage from the main board to the power supply which tells it to switch everything on Im guessing that something is going wrong on the main board. In the condition where it freezes it (the power on V) which switches everything on i get varied voltages such as 2.5 or 3 or (the normal 5v) and then when nothing powers up (blank screen) i read 0v on pwr on voltage but all my other voltages are corect (24v to inverter, 12 v to main board, 5v, etc.) Im guessing from researching this is that there is in improper voltage somewhere in the main board circuit. I have been unable to find it so i may order another board and post back.

If you have not been using the TV for quite sometime, moisture would have developed some defects inside the TV when you switched on. Sometimes even insects and lizards might get in and cause short circuits. Anyhow this might require attention by a qualified service technician.

The TV can't read the format that the data is in, it is a kind of code, your tv can decipher it.

Send your email address to me by Fixya comment, and get a copy of the service manual by return mail.

If half screen is affected it will be either a board (LCD and Plasma have different names) but in those one board drives each side of the screen unit--worst case is the display panel itself which is fatal from a cost point of view.

Power board is of course most likely problem here and I presume you found no puffed up caps on the board.

use different input

Hi. Maybe a fuse got burned, you should take it to a service center.

The main board of this Vizio is known to fail after some use.

Its number is CBPF9D1KZ4 and as you will see it is hard to find, unless you want to pay $250 or so, which doesn't make any sense, at least to me.

Another common failure in those is the T-CON board, but from the sound of it the problem you have is in the main board.

Here's what I'd do if I were you: post a local ad on Craigslist, sell it to the highest bidder and use the money towards puchasing a new TV.

Not sure it's what you want to hear, but it's what I tell some customers and thus losing business that I couldn't have had anyway because it's insanely expensive and prone to more failures anyway.

If it helps you please vote for me - it helps me in turn :-)
