I have the same problem. I finally convinced JVC's tech support to help me out (they **** by the way) and I got the schematics for all the boards in the unit. From looking at them I believe it is the Digital Signal Board. I will post results soon.

    Replaced digital board and it works fine.

    The only problem I ran into is if you power the unit up with the cover off, it will lock out the HDMI input. This can be unlocked very easily. Follow these steps:

    1. Bring up service menu (push sleep timer; while 0min is displayed press display and video status simultaneously).

    2. Run self test.

    3. While self test is on screen, power tv off.

    4. Unplug unit for 1 minute.

    5. Power on and verify HDMI operation.

    Hope this helps.

    Hey hawg082, do you still have the schematics and/or why did you conclude it was the digital board? I have the exact same model TV, and it went black with the blue power light (normal constant on) is functional. Do I also need a new power supply? Please let me know if you can help out!

    No,if the power it is constant on and a solid LED power indication light. U check the power supply carefully no dying capacitor. 99.9% Tuner digital board it is dead.

RCA led tv won't turn on

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

JVC LT40A320 turns on but no picture. Replaced Power Supply & Backlight Inverter (TV was hit by a lightning surge, would not do anything at first) now the green light comes on but no picture or sound.

Since your TV was struck by lighting, the power supply is the first board that gets affected by the sudden change in AC power.. The main board is the next board due to the fragile components and the excess of voltage that is supplied to it when the lighting happened. Since you have replaced the power supply already.. I would suggest to replace the main board and that should restore the functionality on your TV.

Fails to turn on after initially running

it could be, this problem is commonly caused by defective power supply capacitors. I will assume that the replacement board is in good working order. The main board would be the next board to replace as it can mimic symptoms of a bad power supply. Just make sure you order the exact replacement part # on the main board. DO NOT ORDER BY TV MODEL #

I have a Insignia NS-L32Q-10A that will not power on. Now power on light or standby. I have replaced the power supply already. All caps look good and fuses check OK. What next???

ok, when you plug in the set, does the power light come on? Assuming you ordered a power supply in good working order, you may very well have a faulty main board. The power supply produces standby power that the main board uses to power the standby/power on light. Your main board also uses the standby power to provide the "ON" signal to turn on the rest of the power supply.

When i try to turn on the tv set only the blue power light is on, not the screen not sound

You may have power supply problem due to bad caps, or bad main board, or shorted circuits that stop the TV from going on to protect itself. You need to open it up and do in-depth troubleshooting.
Please read my guide first if you are going to DIY repair.

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series
