backlight may have gone if your tv has one

That sounds like the backlight system or its powersupply has failed. If you can see an ghost like image when close and at an angle near the dge (depends on the light) then this confirms the backlight being the problem.

Repair cost should be about $100. You should be able to get this fixed under warrenty if you have any. If not get repair estimates before doing anything. It should be worth fixing but it never hurts to know if it is getting close to what a new replacment tv is worth.

checked the vedeo section of the main PCB of the unit, maybe some defective parts, try to look the back of the picture tube if theres a light, if none, cheke also the horizontal section, especially the flyback transformer

most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each
