Dynex 32" tv picture goes black

If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.

When turned on ,nothing comes up,no picture

there is a connection between the inverter and the powersupply. on this connector there should be a line that supplies 24 volts. if you are getting that 24 volts on a volt meter the you are most definatly looking at inveters. if you dont powersupply. just a warning if you have 24 volts and the inverter doesnt work you need a new lcd panel, which is not worth buying if you can find one

TV screen won't come up

The power supply board or inverter. The power supply board is the first step. Look for any capacitors that are puffed up. Replacing them should take care of the PS. Check to see if you have 24 volts going to the inverter. If you do PS is OK and the inverter is most likely bad...good luck

LCD tv issue

at error code is 12 and it is your 12-volt supply. Measure from the inverter to the power supply for 24 volts pins 1,2 and 3. If you don't have the 24 volts disconnect the inverters from the power supply and see if the volts come up. If the 24 volts come up replace the inverters. If the 24 volts are still not there replace the power supply. The volts have to be steady and not going up and down if they are replace the power supply.
But if the 24 volts are there with the inverters connected 1M03 pin 3 for 3.2 volts. If the 3.2 volts are not there replace the small signal board. The only way to get a manual is to find it on line or call the manufacture.
