SOURCE: Apex GB51HD09 will not turn on

On the power board you will find 4- 35Volt X 1000mfd radial lead capacitors on the right rear corner of the board all in a row from right to left, the 2 outside capacitors have gone high ESR. This is a common problem with this model.

SOURCE: Problems with my Apex CHKT2A remote

I've seen remote sensors that quit but it's rare, usually due to water getting dripped on them from cleaning. Pick up a cheap programmable remote and see if it will work. Long shot, check the menu, in some sets the remote can be programmed off.

TV turns on then cutts off


that buzzing is the high end power trying to turn the lamp on.... the electrical current and shock is what turn your lamp on your tv which is what the buzzing is dont worry thats normal...however your solution is buy a new lamp for your tv but make sure its the right serial number for lamp u cant just buy any lamp. best place to buy one ebay.... as in the lamp still trying to light up its only because the electrical current going into the lamp and then cutting off causing the red light on your tv....so other words all it is is the lamp... CAUTION!!!! those lamps get up to 400 degrees unplug tv to ensure no electrical current.... hope i helped.... JACOB WINKLER
