Most likely you have a bad power supply board and this will need replaced, either by yourself or a qualified tech. You will get a warranty if you have a tech replace the bad board.

Fix lcd tv


You need to dertermine if the power board failing charred the connectors, or if a differeb=nt component failed which charred the connectors and took out the power board. This will require component level testing. i suggest taking it in to the repair shop.
However, i would price shop a comparable replacement TV before fixing a 4 year old Insignia. it may be more cost effective to just replace it.

My flat screen sanyo tv screen wont turn on. the green power light is on but not the screen. any solutions?


Try disconnecting the connector KBL on the main board as shown in my picture #DSCF0585 to see if the backlights will come on, if it does, the main board is bad.
Also check the voltages on the output connectors of the power supply.

Flashing power button tv won't turn on Nothing on screen does not respond to remote. Pressing and holding power button on tv does not work. Screen is black and power light just flashes. Tried unplugging....


yes call the tech and have the power board replaced. In future have the TV plugged into an anti surge board to protect it ( and you from expensive repair.) I suspect you will need a new power supply fitted
