DYNEX 22" TV g0es black after PLEASE WAIT

SOURCE: tv turns on screen displays Please Wait then goes black

There's a problem with the power board communicating properly with the interface board aka 'main board'. There's seems to be a logic problem here _Data-Bus interference. This could be because of DC voltage shut down or an under-voltage condition on the power supply board. Also the serial data too and from the Timing control board could also cause a similar problem. You can send the power board and interface board too me and I'll repair the problem for you. Or if you have some test equipment I can show you what to test.

Get back too me when you can.


Please rate this answer :-)

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

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 the picture goes out, try to open and access the TVs menu using the Dynex remote. if the menu fails to open up you can bet there is a problem with the backlight on the TV. Letting the TV rest and then it working again indicates heat as the source of the problem. Check to see if your still in your 1yr warranty or if you have a protection plan at best buy, the TV needs help.

If the Menu were to still open, you can blame your cable/satellite set top box.
