Re: plug in tv and doesnt work
If you have no Tv repair experience, how do you know what part this is?, as I dont have a clue as you didnt supply a schematic or a picture of what the part was. We techs have a trade we learned not by doing but by going to school to learn the theroy behind the circuits. If you know how to read a schematic diagram, i suggest that you get one and know what part it is that you think you found burnt out. If you go to http://www.servicemanuals.net, download a service manual or schematic diagram, i will assist you in this repair as long as you have the proper equipment such as a mutimeter and know how to trouble shoot solid state electronics. Its not a tube you can take out and test or a board that can be exchanged anymore my freind. Its down to the componet level these days.

The tv power supply board it is dead 100% it is dead that board where the tv power a/c plug into it.Sometimes u get a burn or a chart coal marks if the power surge have big enough charges to the board,not it still kills board too because electromagnatic charges of the storm kills every electronic parts in came in contact with.Take the tv aparts.The tv power supply board are alway the one these two boards are the causes alway and the first board to dies .Replaced the tv power supply board first.Tv should work now,if not the main tv Tuner signal board it is also dead too.That the board where the incomming broadcasting signal wire plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement first and also the main tv Tuner signal board too,if necessary.70-80% changes the power supply board and necessary the main tv Tuner signal boad too tv should work again.20% sometimes the whole tv it fries and a total lost.
Take the tv aparts.Take the tv manual control board aparts.Reajusting the board and screws it back in.Should solved ur problems,if not than the whole tv Tuner signal board is the causes and the problems.That the board,where the incomming broadcasting signal board plug into it,this board have intermittent problems and the causes.Try website like Ebay.com t buy a whole refurbish tv Tuner signal board for the replacement.
I assume it was the power supply that you replaced? It is very likely that a fusible device on another board has gone open circuit to protect any damage due to the initial problem. Again I assume you have a plasma TV in which case there will probably be a problem on the Y or Z sustain boards which may also need to be replaced as this may have been the reason for the other board to burn up
Okay, if the screen is white! First, take apart and check the ribbon like cable that goes from your signal board (where you inputs are plugged in) to the lcd controller (under a small metal plate feed the lcd screen), see if loose and or reset! Secondly you either have a bad signal board or lcd controller!
That small black piece, was it somewhat flat? I am thinking that it could be part of the fan or baffle. As far as the smoking when you had it apart how did the windings look on the armature and field? It is possible that this piece of plastic opened up the windings and there is a short in the electrical components. If that is the case I would suggest taking to a repair center to get is looked at. Let me know what you find
