Reset dynex tv


You can reset the unit by unplugging, wait 30seconds to 1 minute.then try again.

If still doesn't come on, the lightning may have done some internal damage, such as to the power supply or Main PCB.

My Dynex 32" LCD tv seems to turn on and off


The blue light merely indicates that power is getting to your TV. It has internal power supply problems.

If your TV dead after the lightning, then your TV doesn't power ON with red light stays on lit you possibly have faulty main board.

If totally no indicator try to replace the fuse on power supply board if busted or blown (it is usually connected directly from power cord.

If the fuse still blown you need to replace the whole power supply board.

please rate!!!

This is exactly why I tell people that when your set isn't working, you have to have it properly diagnosed. Chances are you have a defective main board. The power indication is an indication that you have standby power. However, the power indicator is controlled by the main board. So it is likely that your power supply is fine but you have an issue with your main board. It is not likely that your replacement power supply is defective as well, but anything is possible. You will need to have the power supply tested. If you are handy with a multimeter, I can help you with that.
