Question about Vizio L37 Television
My tv won't turn on. The orange light is on - will not turn green and go on. Have tried disconnecting from power, using remote, manually hitting on button.
Ok I'm just going to copy paste here being as this might work for you guys, I tried it my self but had no luck but my issue has slightly different behavior(led goes green for a second before dieing). any event here is what I found:

DEAD WITH AN AMBER LIGHT
Do Not Order A New Board For This Vizio Model. You Can Fix This Problem For Pennys. Problem: Will Not Power Up Amber Led Only. Hint: No Reset To Operate Micro (Brain Dead) I'Ve Seen (3) Various Fixs Below, One Uses A Diode, Other Uses A 10k Resistor, Try Either. All 3 Will Work, Diode Works Best For Me This Same Reset Ic Goes Bad On Other Visio Lcd & Plasma Tv'S. #1) You Remove Smd U26 On The Video Processing Board And (Add) Put A 10k Resistor Across Pins 2&3. U26 Is Near The The Tact Switch. #2) Remove U26 And Solder A 10k Tru 100k Resistor Across Pin 2&3. Start With A 10 K First. #3) Remove Reset Ic Near Tac Switch Replace With 1n4148 Diode (Nte519). Vizio Tech Support: (Valid - I Tried It) 1-888-849-4623 Opt 4 Technical Support: 888-849-4623 Try Extension 1669 (David).

I bought a "broken" L37 on e-bay for $175 figuring as an Electronic Engineer I might be able to fix it. Check the power supply, if the front panel LED is orange and the V1 voltage at the power supply board is about 5.2 VDC and the V2 is about 1VDC you can check the V3 voltage (display backlight?) by removing the " remote" black wire from the conector (very gently lift the white connector tab) and jumpering the connector onthe power supply to 5V to enable the V3 supply, if V3 is 50 VDC then its probably the logic board. I will post again if I can figure out the logic board problem (Crystals or capacitors are high probability failures) otherwise its $200 for a new one! :-(
