    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.

Toshiba 32c100u dead; power supply board replaced but still nothing


Have you checked whether mains power reaches the power board? Check it first. If yes, the power board you purchased newly should be checked.

NO power


That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

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.
