Simple. take the stand out first, then the surrounding screws on back cover. Remove back cover and the power supply is just right there. Make sure you wear ESD or you may short out the fuse.

If anything, try taking it to a tv repair shop and see if they can find something wrong with it by looking at it which I am physically unable to do online. See if they can look at it free and tell them what you have replaced but I don't know what else without looking at it myself. I hope you get it working.

I doubt you can get a free inspection of it but you can try. Possibly let them know how much money you have spent already and maybe they will give a little leeway. Good luck.

SOURCE: Vizio TV (L37) will power up but no picture

The backlight is powered by its own supply (although it may receive input from the main supply) and it sounds like the main supply or one of its outputs has failed disabling the video and sound processing.

SOURCE: LCD controller board location on Vizio L37

Display controller is usually under the Main board which you remove to get access to it. Display controller connects to the suis-boards which then send signal to the screen of the TV.

Vizio hdtv went POP then black while watching a program. Reset did not help.


sounds like a power supply failure open the unit and inspect the power supply for any damage type bad capacitor into google and look for any bad caps on ur power supply
replace them

if all else fails replace the power supply

please make sure to disconnect your tv from the mains and wait at least half an hour before doing any kind of work to it as it may still hold a charge that could harm you

My vizio l37 hdtv went black it is getting power the light stays yellow and does not go green. tried to rest it through tech support but nothing.


You need to replace the main board (signal). It is the board with all the A/V hookups on it. The part number is a number with 3 sets of 4 numbers and at the end of this number there is a number letter sequence with ( ) parentheses around it. Do a search on ebay and you should find one. Be sure to match the numbers I mentioned to the one on ebay!

My Vizio L37 is on with no picture


Most likely a defective power supply module which can be repaired to component level. A local svc co. would be your best bet now.

Check all electrical connections. If standby light is off when plugged in, probably needs Power Supply board replaced. If standby light is on (Orange/Amber color) may need Power Supply board and or Main Board. If set was shutting down on it's own leading up to it not powering on at all, may need Main Board, and possibly Power Board as well. If standby light has changed from Orange/Amber color to Green, the set IS powered on, and you have an issue other than power.
