Lcd tv wont turn on when hot


Either you have to take the TV into a service shop or aim a fan at the back of it to let it stay on longer getting some cool air on it :)

A primary reason for electrical overheating is dust. You might want to get a spray air can and spray out dust where ever dust can get inside the TV.

That's really a temporary fix or something that can prolong usage, but ultimately the TV will need servicing.

NEC NLT-26HD1 The picture flickers on and off when turning on (cold nights especially) but the sound is ok. And when using tv information/guide and playing games or DVD's.


the main control module has a minor problem and needs to be replaced. eventually you will notice other things start to happen like flashing or colors changing.. take it to a good repair shop...

No picture no sound


Hi!

It sounds like you have a power supply problem! You will probably find some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain). In addition check the ribbon that feeds the lcd controller.
