howdy, i have a request to know where someone can buy new COF or tab bond ribbons? i purchased a used samsung un55h7150 with the story that the "audio worked but the screen just didnt show anything". i was like "hell yeah, i can slap a new led on the strip and have a perfectly good 3d top shelf tv for the price of peanuts".
well, i get it home and after bragging to the wife about my score, i plugged it in and turned it on and there were lines on both left and right side of the screen. i was mad, but hey thats karma, and usually before i buy a tv i plug it in and check it just for the heck of it. but this time i didnt, and it is always a risk buying tv's like that.
anyways, i got it disassembled and sure enough the tabs were the problem. when powering on, the 3rd tab from the right would get blazing hot to the touch and then the tv would turn off. id have to unplug it to get it to come back on. i got the bright idea to take a soldering iron and some heat resistant tape and i put the tape on the pcb side of the tab/cof/w.e it called right over the connections. i went over it a few times slightly slowly, working the solder iron back and forth over each connection trying not to let the iron sit in one spot for long. i got done the first time and noticed a drastic improvement but there was still lines.
so i went over it again, and this time a little slower. working it, multiple passes, making sure to heat it up good but not to much, paying very close attention to it. i got done and let it cool for a few mins and then turned on the tv and viola! it worked! i was purely amazed. the tv stayed on and everything. i was the tab bond king and noone couldnt tell me i wasnt a professional! i went into the living room and told my wife again, how good of a job i did on the tv then returned back to the room to see the tv shut back off. upon further inspection, the tab bond ribbon got so hot it melted a whole through it. i was in pure anguish. i couldnt believe it. i was so close to having an awesome top shelf 3d tv for the price of hardly nothing.
anyways, that brings me to the question. i am looking for some replacement tab bonds for this tv. the bottom side. if anyone has any idea where i can find them please let me know. i am certain i can fx this thing if i just had another ribbon/tab bond/COF. thanks in advance
edit: i have other tv's that are bad thats around the same size, would any of those TAB's/COF's work?
