SOURCE: My Philips 42 inch flat screen tv keeps cutting


There seem to be a problem with the power panel of the television that is why it does not power on if you leave it over the night without trying to turn it on.

Flashing the green power LED light simply means there is a problem in the unit that is why it keeps cutting.

Run a check on the power panel of the television to see if there is a burnt capacitor in the unit, then replace if you find any, also, a cold joint can be a cause for the problem whereby, you have the lead on a capacitor or component melted off and bridging two wrong ends together. That can be corrected with the use of a soldering iron.

If you are not familiar with technical activities, i would strongly advice you have a repairman run a check and fix it for you. It should not cost you much and if it is still under the warranty period, then you can take it back to the dealer that supplied it to you.

Take care

We have to push the on button on our TV from 20-100 times to get it to turn on. Have changed batteries and restarted to no avail.

"He said our TV has a problem". Brilliant! To be more specific, he could have suggested switch failure or a failing power supply.

50 in proscan led tv powers on then has black screen but can see screen work with flashlight

Your backlighting is no longer working.
With a LED TV it's an array of LED's that light it, in an LCD TV it's fluorescent bulbs that do the backlighting.
There's a chance it's the power supply board that's bad, unfortunately, it could also be the backlighting itself.
You'll need an expert to look at it to make that determination.
If you don't know Electronics, don't open it up yourself! There are hazardous voltages even in flat screen TVs. The hazardous voltages are there even when the unit is unplugged!

If it will switch ON, and won't power up, surely the LED at its front panel will blink to a certain time. These LED blinks are fault indications. for more detail either try to download its service manual from internet, or try to enter any service help sites.
