42" LCD picture is tartan !!!!

[chris1974]

I bought the tv off a man in a van !! im an idiot i know ! i turned it on and the screen is tartan but i have sound, the colours on the screen change but it is far from being a picture. I have been told that there is a set of microchips that go on lcds and it is probs one of those, they attatch to the side of the screen with ribbon wires , i found these chips and disconnected them and it made no differance to the picture at all , so im no repairman but that must mean that is the broken part !?????? i have part numbers for these chips but have no place to get them from . I have no idea what the model number of the tv is as all the serial numbers have been removed !!! the inside of the tv is all LG stuff tho. i really need help sourcing these parts and would really appreciate any feedback , my wife is gonna kill me if i have wasted money buying a busted tv !!!!!!!! cheers ..... i can post pictures if that would help ???

I dont know if thats usful !!!??

[chris1974]

tried that no change in the picture, where is the Y-drive so i can see if it has a part number on it ? I really appreciate you helping by the way . cheers . if this has a part number can i order the parts through you ?????

[mulja]

Take ribbon cables out off both drive panels and clean sockets. If this dosn't work wife will kill you as both panels would cost £200.00

[chris1974]

i will try that after work tonight . fingers crossed !!! i will let you know !!!!!!!!! and thanks again ..

[chris1974]

Well well well the whole bottom of the screen is totally free off black bands !! But the top still has the lines.I have cleaned EVERY YES EVERY !! connection on the whole tv and checked they are in right ! Its probabley in better shape than when it was made !!!!  So with my inexperience i still think its got to be one of the chips or two ? that have gone now . So i would like to know if you could either order me a board or point me in the direction of somewhere to order from ??? On the list of numbers i posted earlier it is the top board. Im confident that this will fix it !!!! !!!! (i hope so !!!). If not its gonna be an expensive coffee table !!!!!!

[chris1974]

Please can you help me with ordering this board??? Could you email me your workshop phone number so i could maybe arrange ordering that boadr if you are close enough i will be able to drive to pick it up and pay ???

[chris1974]

Mulja please help i am confident that this part will fix my tv . None of my local repairers can order this part im stuck !!! Im not giving up on this !!!!!! Please let me know either way ! the cash is here i just need the part !!!

[mulja]
