unplug the unit for 24 hours and try it again. if the unit doesnt come on at all, even after that, then the internal fuse is blown, or a power spike / surge has friend part of the internal power supply. you'll have the go through the warranty process of the manufacturer, or find a local tv repair shop.
Senor....You have 2 bad capacitors on the deflection board..They are 160 volts 1 mf and you may have to check the the large Horizontal cap , I think it is 25 volt or 35 volt 1000mf cap. Good Luck PS Look for 250volt 4.7 cap is bad too! DE NADA!
there is a broken conductor strip or broken solder joint on the circuit board near the power input jack. do this:
1.) disconnect tv and open panel to expose circuit board.
2.) using a flashlight and magnifying glass, look carefully for this broken solder strip or solder joint. Flex board slightly if necessary to aid in finding the break.
3.) repair it using solder iron and flux solder and scratch copper conductor slightly to aid in "wetting" the solder fix.
