    I own a Proscan 37LA25T, which has a power supply problem as well. The board is a Megmeet MLT070A Rev 1.9. I have not had any luck in finding this board. Any help would be appreciated.

My Proscan TV has sound but no picture


Back - light problem. 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.

My proscan tv has the blue light but wont turn on


Most likely it's the power supply board that went out. (part of it still works is why you get the blue LED when you plug it in.)

If you decide to try to fix it yourself, BE CAREFUL! The power supply board has capacitors that can hold high voltages for many hours after the TV's been unplugged.The equivalent of sticking your finger in a light socket.

You'll need the part number off the power supply to get a replacement.

'Standby' lights momentarily and then shuts off completely; no video at all; about 2 yrs old;purchased from Crutchfield


if there are no led lights at when the unit complete powers off you may need to replace the main board(input board) or have a skilled technician take voltage readings at the power supply board. check your power cord and the outlet you plug into as well.

If the fuse blows again after replacing it, there's a shorted diode, bridge rectifier, capacitor or transistor in the power supply.
