Re: LG 50PC56 keep burn Buffers Boards
Good evening bro, yes they get very hot even with the buffers properly install! I will order a buffers set tomorrow, I didn't order it before because I wonted to be sure that the panel is good before buy it, I have already spend a considerable amount of money...I will have to buy used parts now from ebay as I'm short of money! Hopefully I will get the buffers this week and before installing it I will consult you, if that's ok
Thank you in advance, talk to you soonLeave a comment:

Re: LG 50PC56 keep burn Buffers Boards
I didn't read properly your message sorry, I meant the ribbon from T-com to Y-SIS, but you were talking about the ribbon from the screen, sorry my mistake! what In photo 5, is the cable push in as far as it goes! It doesn't go any furder than that bro, I can guaranty you.
Which wires come out of picture? I don't understand what do u mean?
I didn't test the buffers with a voltmeter because (again) the IC get very hot which mean that is not good innit? If I had only a suspicion that was working I would have done...Leave a comment:

Re: LG 50PC56 keep burn Buffers Boards
Ok, but I did check the connection and look ok! If I do install a new set of buffers how do I know that the connection are bad without switch the set on? To me the connector look ok I pushed them well inside and the slap close well..Can they be damage? Thank youLeave a comment:

Re: LG 50PC56 keep burn Buffers Boards
Hi, sorry for late reply but I could'n do it before. The buffer are not good! My worry is that if I bay another set of board will blow again! Are you sure that the missing screw was the reason of blow it up? The picture are take after I replace T-COM which the output is the same but much brighter. I assume that I brought a faulty T-COM tho, let me know what you think! You help is much appreciate. Thank you...Last edited by gatto; 05-07-2022, 05:13 AM.Leave a comment:

Re: LG 50PC56 keep burn Buffers Boards
Good morning! Thank you, i didn't know about screws!
Do you think that my problem has been the missing screws tho... If so I can’t justify my ignorance! I could have read and asked more question before start working on this television! So I fucked 2 set of Buffers because of it!! What shame of me!
Now, do you think is still possible to get this set working again, on your opinion could be that as result of missing screws something also now could be broken? if I get new Buffer with all the screw on It will work? Do...Leave a comment:

Re: LG 50PC56 keep burn Buffers Boards
Good morning, thank you! Don't worry, I would have say the same from what I'm describe to you! I was assuming the same and it's still considerable. I saw the video you sent, but my set is different, and the board is not the same, if I know where are that testing point on my board I would check it. I send you a picture of my board, probably you know that. But as I said, I'm pretty sure that my fix did't work, Is not easy (at least for me) desolder a chip without damage it as it's cover in silicon, I been look for new IC but is more expensive...Leave a comment:

Re: LG 50PC56 keep burn Buffers Boards
Hi, thank you for reply!!
I was going to give up I have take out all boards with the intention to sell them in eBay to recover some money! But then I change my mind I did put everything back as I had the idea of desolder a good IC from one blowed set of buffers boards and solder it in stead of the one that I know was burned on the last board I brought..I did install it and now I got very dark screen with large set of moving vertical line, that I assume it is the no signal logo, if I press menu on remote I can see the set of line getting...Leave a comment:
