How do I fix my Vizio P759-G1 TV?
Chances are your LED backlights have failed, slimer possibility of LED driver board issues but usually it's the backlights causing it.
Vizio 55 in V555-G1 LTCDYILW Top of screen is black
This model TV has what's called local dimming, on most brands LED lights are wired like christmas tree lights, take one bulb out the set is dead but on most Vizeo sets each strip has it's own power sourse, chances are some of the strips are bad and need replacing but if you replace one replace them all
I have a black picture, but have sound. Vizio VW26L HDTV 10F
The back light on the Vizio VW26L HDTV10F may have failed on the TV. In the past year, I've had one monitor and one TV (both over 10 years old) fail with the same black screen with clear audio. The way I confirmed that the problem was the back light involved lighting the screen at an angle (in a dim room). For the monitor, an overhead recessed light let me see a "ghost" image of the open program. For the TV, I used a flashlight held to the side. Then I was again able to see the dim image on the screen.
With the TV, I was able to continue using the TV for another few weeks. I had to unplug the set and wait for several minutes. Then, after restoring power, when I turned on the TV using the physical power button, the back lighting would come back on. However, after a few weeks, this method stopped working. (The monitor back light did not respond to a similar removal of power.)
The copyright date for the manual is 2007. I believe the best option is to replace the TV. It isn't worth fixing the back light on a small screen that is this old.
I wish I had better news for you.

(My old screens both had compact fluorescent back lighting. The replacements use LED back lights. The power usage for the electronics thus is considerably better with the replacements.)
Vizio V585-H11 blinks white screen
I've seen this issue many times on this series of Vizio sets, you have a bad EEPROM IC on the main board, either change the main or order and solder in a new IC if you have advanced soldering skills, needless to say the chip will be a fraction the cost of the board.
Vizio TV D50x-G9 won't power on
Bad TV PSU (power supply unit) and seems dangerous to me.
arc'ing? sounds. I'd not plug it in to AC wall power until fixed.
did water land on TV?
why not get a shop to fix it?
or buy \the shop manual
the manual you don't have may say
the main board needs to be reprogrammed to use this size 50" screen, and if not done by the book there is no hope.
learn to RTM first, no 2 TVs are the same.
some have 1 main logic board that works on 3 screen size models.
why not get shop to do that? and not pour cash down a pit. to zero gain, why?
what if the PSU was overloaded, even the LED background array can do that if bad. so replacing the boards 10x will not cure that. see???????
next time by LG or Samsung. far far far better long lasting TVs
and 10x better service, (consider that)
I have a large darker than the rest of the screen on my vizio tv
The Vizio "E" (economy) series sets have local diming, on most brands if some of the lamps go bad the screen is black but not on these model Vizio TV's, for this reason it's harder to troubleshoot the set for possible bad backlights or backlight inverter issues. If you have a LED backlight tester you can test each zone at the backlight connector off the inverter board to see if each is working, without a tester you're going to need to remove the panel then move strips that don't light to ones that do and see if it's the strips bad or inverter issues.
How to fix a Vizio M420SL Edge Lit LED TV with dark corners
Edge lit sets have a tendacy of having sections of the backlights bad, there are 4 to 8 zones with about a dozen lamps in each zone, if you have dim edges the outside sets have failed. The issue with replacing them is the lamps get very warm before buring out and in most cases, it damages the defuser panel, so it doesn't spread the light correctly. Start by taking the screen (panel) out and defusing screens and see if the thick one is damaged, either cracked or warped, if it is it's time for a new TV, if it looks ok you can get parts from shoppjimmy.
Navman icn320, very sticky rubber case how to clean?
To remove the stickiness from you Snooper sat nav use a white none scratch saucepan scourer and Cillit Bang black mould remover. Use only the mould remover do not use any water. Use just enough mould remover o moisten the scourer to avoid getting liquid into electronics. It takes a bit of work to clean the corners and nooks and crannies. Protect the screen from damage while cleaning, the remover itself will not cause any damage to the screen. Don't put too much pressure on and the sticky mess will come off.
Half of Vizio E65-E3 LED Strips Don't work
Unfortunately, this model Vizio set has a lot of issues with the backlights. I believe I've posted this before but going to again, before you buy a Vizio TV check the model number, if it starts with an "E" keep shopping, the E stands for economy series and in most cases the sets only last a yr or 2. I'd be suspicious of inverter issues, the defective lamps damage the power board inverter, start by testing C203 and C204, you should see the same voltage on both caps. If one has no or very little voltage you need a replacement power board. If the voltage is close to the same (one will be a little lower as it has the lights that work on it), I'd lean towards a connector issue, this set has 4 individual regulated supplies for the backlights, they're fed from 2 inverter rails, it appears one rail is working and the other not, this points me in the power supply issue.
Vizio v505 won't power on.
Throwing replacement boards at the TV without doing some voltage tests doesn't make much sense. It could have been the power board, it could be the main, it could be a tcon or panel issue although chances of these are thin, also could be bad backlights
