When i turned on my 47 in. tv vizio the screen
It may have shorted out and blown components in the power supply module, that will be the first place to look.
Please read my guide first.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

The location should be on the left side,and right side. if the TV is face down and the stand is next to you. If your TV has sound and no video, you are correct that the inverters are bad. Part #6632L-0486A/6632L-0487A. Thanks for asking, Matt of Martins TV Repair.

Today my 55" vizio screen popped and then turned red. I unpluged and restarted everything and now the audio is on, the chanels change, but the screen is completely read. some images are readable.
If this is a VO47LFHDTV20A TV set, the problem is most likely your LVDS(cable from the main board to the t-con)cable is faulty. When you turn the set on, do you have a red screen instead of the standard blue screen? Do you also have red tints on all images on all inputs? If this is the case, your LVDS cable is bad. If you are comfortable opening up your set, track down where the LVDS cable goes into the t-con board. Turn on the set, and wiggle the cable, if the red tinting goes away, you will need a LVDS cable, about $24 part.
Need the code for the charter remote
For example, to search for a code for your TV:
- Turn on your TV.
- On the remote control, press TV once; it blinks once. Then press and hold SET UP until the TV key blinks twice.
- Enter 9 9 1. The TV key blinks twice.
- Press 1 (the device code digit for your TV). The TV key blinks twice. Aim the remote control at the TV and press POWER once.
- Press and release the CH+ key continuously, then stop when the TV turns off.
NOTE: In the searchmode, the remote control sends IR codes fromits library to the selected device, starting with the most popular code first.
- Press POWER. The TVshould turn on, then press SET UP to lock in the code.
NOTE:
If the TV does not turn on during step 6, then slowly press and release CH- to go back through the codes, then press SET UP when the TV turns on.
Vizio VO47L FHDTV10A black screen no light
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
