Common LG LCD TV REPAIR - NO PICTURE OR BLACK SCREEN FIX ... came on good with green light working properlybut still no picture.
Sorry the problems,ur tv it is having,it can't be repair,the tv Plasma screen panel itself it is shorted and dead,that why the tv plasma screen panel have only a third of the plasma screen panel it have a good clear picture and the other 1/3 of the tv plama screen panel is black and dead.The tv that have a broken or shorted dead plasma screen panel it is not worth repairing,because only way repair it is by replacing the whole entire plasma screen panel itself.The tv plasma screen are about 90% of the cost of the tv and can't buy it anywhere else except the tv corporations dealers themselves.Sorry tv now,only can be salvages for those electronic boards for parts that it.
this sounds like screen burn with rear projection and plasma when a picture is left sitting still on the screen sometimes it will burn in to the screen rendering it useless i left my ps3 paused on my old tv then when i changed to bbc one it still had a faint call of duty pause screen in the back it can vary from things like that to logos to your black rectangle the only way of repair is by replacing the screen all toghether i would advise you to just take the screen off and start using the tv as a projector if you cant find a screen it is only a bit of ribbed plastic but very hard part to find
Hi, Do you see same solid black box in all inputs or just in dvd picture? If solid box appears only with dvd picture then its generated by dvd player, check dvd player Menu and turn off any subtitle settings. And if solid black rectangular appears in all inputs of TV like cable etc then check Close Caption feature in TV and turn off CC function. Hope this will solve your TV problem. Thanks.
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
