Re: LG lines
Looks like tab bond on panelI assume no responsibility for any stupid suggestions I might post. -
Re: LG lines
Death by windex? Look at ribbons coming out of panel at bottom,look closely at them where the lines are. Corrosion on them?Proud owner of dozens of broken TV's and many,many,many boards.

Re: LG lines

Re: LG lines
Ribbon bonds aren't repairable without multi-thousand dollar machines. No contradiction at all.Comment

Re: LG lines
That's not a contradiction. Not all ribbon bond failures are repairable. Generally only those between the ribbon and PCB are. Those between the ribbon and panel are essentially not repairable unless you have an LCD panel rebond jig...not going to happen.
too long didn't read - panel's fucked.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: LG lines
Death by windex(household product people use to clean glass surfaces),might have a different name in your knack of the woods,is an expression used by many of us here .
What it means is that when people clean their tv screen with a product like windex or any other liquid type cleaner,that in the process of doing that fluid can run down the panel and hang like drops off the bottom of the panel,inside the tv,right where the ribbon cables come out of the panel. Over time this can cause damage to those ribbons.
Hope that gives you a better idea of what I was trying to say.Proud owner of dozens of broken TV's and many,many,many boards.

Re: LG lines
Liquid can run down the screen and cables and sit in the connectors and corrode the contacts.
I have been lucky and been able to repair a couple in the past by soldering in fine wires direct to the soldered pins on the ffc sockets.
I've also see it destroy tab bonds.
Only way know for sure is to strip the panel down.Comment

Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side... -
Hello again good souls.
Got an UE70TU7100. The TV starts up just fine, but right hand side of the screen is horizontal striped a bit, and there are some flickering horizontal lines on the whole length of the screen. I've seen similar static horizontal lines sometimes, when applying the cut tape method and covering wrong number of pins.
I've cleaned every connector with ipa, tried cut tape method on main LVDS ribbon as well as small ribbons, connecting the panel boards at the bottom. Tried squeezing the bezel and playing around COFs, but no reaction at all. COFs and... -
Hello,
First of all I'm new here. While looking I found this amazing forum and I'm very happy I did. Now for my problem:
I picked up a Samsung UHD QLED QE50Q67TAU from 2021 for $50 knowing it was defective. The seller said it had black lines and that it could get stuck in boot randomly.
I've tried a new power cable, hard reset, opening up and jiggling all cables, pressing everywhere to see if I get a reaction but I've gotten nothing. I've tried the tape method but I've only managed to get the lines worse.
I'm no expert but I've done the tape... -
Hello:
I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.
I started on the ACER:
Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.
I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap... -
Hi, I'm new around here and hoping that there may still be some people on here that are knowledgable about plasma display repair, as some of the old badcaps forum posts have been pretty useful to me so far.
For any regular plasma TV I probably wouldn't bother to go through this effort, but I have a pro-grade Pioneer plasma which I really want to use and it would be a shame to throw it out since there's not many of them still around these days. The plasma has the typical black horizontal lines that seem plague plasma displays. I've counted 3 lines on top of the screen and 4 at the...
