I have an Emerson TV/ DVD player. Seems to be nothing wrong

Customer Question

I have an Emerson TV/ DVD player. Seems to be nothing wrong with the power supply. Fuse is OK,LV diodes check OK. Red indicator comes on front of TV, but that's all it will do. May have been hit by lighting.

Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it.
I need additional info to troubleshoot the issue.

- Does power indicator light change its color when press power button?

- Does screen glow/ show backlight when press power button?


Customer: replied 1 year ago.
Power indicator stays red. No glow or backlight when power button is pressed.

Thanks for the info. It needs further troubleshooting inside TV with voltmeter to check Power On command/ volts on power supply board which will help to determine what board is defective, I'm sorry this would not be an easy thing nor any easy or quick fix available because it looks hardware related failure in TV.

If Power On command/ volts goes low or high on each press of power button then it would be power supply board failure and if you do not get any change at Power On command/ volts then main board will need to be replaced. Please check with following supplier to get required replacement board..

I trust my input will help you out. Please feel free to respond if you have any additional questions.
