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).

It sounds like the main power supply board. If you can hear the relay click but no other response from the TV, it would be a good bet to start there.

I just replied to a similar problem on the same model TV. If the relay contacts are no good or if there is poor soldering on the main board, you'll get this symptom. Although a bad set of relay contacts aren't out of the question, I think it's more likely that there are cold solder joints on the board. If this is a relatively new TV and used to work fine, the thermal cycling when the TV was operating might have been enough to cause intermittent contact with the solder joints. If you're up to it, consider resoldering the main board especially near the relay section. Let me know what happens. Please rate accordingly.

L37 vizio lcd

Do you see any burn marks or leaking components on that board? If the TV's power supply thinks it's on then it would make sense that the problem is on the main board. I've seen it here for sale: $126 bucks, not bad.

First try to look really close at the screen to try to see if there is faint evidence of a picture, if so then the problem is with the FL inverter that drives the backlight. But if there is no sound then it's not that but the main board. Good luck!

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!

I've got a 37" LCD made by Vizio. After about twenty min. the screen start to flutter or flicker like a strobe light. Power on the unit stays on while this occures. What cani do to fix this?

I am having the same issue, I think the best solution is to replace the inverter slave and master boards. These are the circuits that controls the backlight and causes the flickering when they are malfuctioning.

My vizio 37" plasma tv has a green line running down the right side of the screen

Vizio does not make 37" plasma TV. for the green line problem, does it happen on all inputs or just when you what TV (cable or satellite)? That line should only be present on some channels due to signal processing compatibility. To get rid of it, you can use the horizontal size adjustment and expand the picture side way.

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.

Vizio model L37

here, try the trouble shooting guide and let me know start with page 56, here is the link

Let me know when you have tried the trouble shooting for picture and sound even though this may not help, Also, since replacing the board didn't work, I will suggest going right to the manufacturer on this since the board was the only thing that really made sense for both to be out. Otherwise there might be a loose connection somewhere, anyway call them and let me know what they tell you and if they can't help, then you might have to take it in somewhere to have it checked, but the main board is the only thing that really makes sense
