L37 tv turns off on own and then will not turn back on

My L37 Vizio turned off on its own while watching the news and now it will not turn back on. The amber light is on (normally meaning tv is off), so it is recieving power. I have unplugged the tv and changed outlets on power strip, but the tv will still not turn on. vizio states i need to have it repaired, but warranty is out.

could it just be the power supply, or do i have a bigger issue?

    My Dad's TV had exactly the same problem.

    The LED glows amber, never turns green, and whole set is dead.



    I too replaced the power supply, but the problem still persists.



    Now I am looking at 2 boards, the "LCD controller board", which has most of the video I/O, and underneath it is a smaller controller board, "Video Box Board Assembly", which has a single tuner input and an ARM CPU. Either board is over $200.00, so hoping to get the right one before proceeding further.

I just did a troubleshooting session with Vizio as my Vizio will not turn on unless I unplug iy, wait about 10 seconds and plug it back in. This is getting worse as time goes by! The tech made me do a master reset and so far so good! Hold the on/off button in while TV is off for 30 seconds and then try it!

My Vizio VX37L HDTV won't turn on. Was watching it one day & it turned off by itself. Replaced power supply with new one with no luck. Orange light comes on but will not turn white.


reset the tv with the tv off, but plugged in hold down the soarce botton on the tv for 5 seconds it should click on and work. if not then there may be curcuit board issues. i found the same tv on the side of the road as somewone was throwing it out, it was leaning aganst their trash can. i brought it home. plugged it in and it went on and inediatly went to the orange vizio light. i rest it and it's been perfect ever since is my comoute monitor now...good luck i hope that fixes it for you..

I have a Vizio L37. When I turn on the TV it works perfectly after about 3 minutes the screen goes to green (no picture). However I still have the sound.


My first guess would be your t-con board. The t-con board is the one that transfers teh picture from your signal board to your screen. My second guess would be the siganl board is bad.

You can get parts at www.interliquidparts.com

Vizio wont turn on!!


I have this problem. Bought at Costco. Called them and was transferred to Vizio. TV still under warranty, so they are supposed to get me another TV. Mine is only a little over a year old. The one they are giving me is NOT new, but refurbished. I'm not happy about this, but what can I do? Apparently, this IS a KNOWN problem.

Boy, what luck! Unfortunately both those units have IR receivers that are using the same code of which you can't change, so I would put a piece of black tape over the stereo's IR window, the only draw back is you will have to turn it on manually. Try it and see if it helps and let me know.

Vizio L37hdtv10a fails to fully turn on


You will have to isolate the main board and Inverters.
Unplug the inverters and turn on the set.
If it "turns on" then try re-connecting each inverter seperately to see if only one is causing the problem.
