Wow. TH-cam put this video in my feed just 59 seconds after it was uploaded and processed. Talk about timing! It's nice to see you back. Those kind of defects are usually inside the panel itself, but it wouldn't hurt to reseat the cabling going to it.
Not as bad as if the panel is de-laminating! Had a Panasonic do that, and it was annoying. Even the lines are bearable for a bar where after enough time, the screen will be too fuzzy to see the lines.
I held off watching your latest video, just incase it was a figment of my wist-ful thinking of days gone by. 😲 Then 3 days later you're still in my in -box, so I powered up my Commodore and, What a treat! Another Great Alley Way Recycle Show!. 😉😋 Seriously: good to see you are OK and back with a video 👍
Good to see you back, you're my favorite of all the vintage electronics restoration channels. Hopefully the screen isn't the issue as I consider that a "deal breaker" when repairing TV's like that one, but if it is, you can always part out the mainboard and sell it. I did that with a 32" set I found which powered up, but had a seriously damaged screen
Hi. We've been using the set a lot the past few weeks. After running a few minutes, the lines will disappear. But then another problem will start up where the screen will flicker and freak out. A whack or two will fix it for a while. Probably a loose connection or flaky T-Con board.
@@bandersentv Don't feel bad, my brother gave me his 24" RCA which to his surprise was DOA when I tried it out. I replaced the mainboard and it worked perfectly but was upside down. Someone sent me a link to a TH-cam video on how to hack into the factory settings and flip it back over
Bob, this info is from my days as an industrial engineer, charged with supporting avionics systems at the vendor, specifically Flat Panel 'glass cockpit displays', during the early phases of the 777 Program. What you need to look for, are either Kapton coated, gold-plated "display flex connectors", which are going to the display driver section, from the LCD itself (LCD is most often directly connected to the display flex output, and that side of the affair is very often potted in mastic. A gentle cleaning with DeOxit, of both the 'display flex pin connector' may cure a possible "interconnection switching issue", whereby the info being sent by the display driver is being lost through poor mechanical connection. I don't see the LCD as being the culprit, as their failures are seldom line-length, rather, they are usually individual pixels, or clusters of pixels, which result from delamination of the layered substrate.
Yes, you're right. There is an intermittent connection issue, I can get the lines to go away by tapping on the cabinet. Have not taken the back off but hoping it's an easy fix. TV works flawlessly otherwise.
Try running the TV for about 10-15 min. If the lines go away, you might be able to fix it (fixed for now but later???). The ribbon cable from the panel is bad and loosing connection. If the lines go away you can shim the ribbon cable to make the connection. Bottom line the ribbon cable on the panel is bad. Glad to see you back and good luck.
I found a TV that left side was flaky like that. Once the TV had been on for half an hour the problem went away. I never bothered to fix it. That TV was also really heavy, like 50 kG
Hey Bob! Great to see you back... honestly though, I had a hunch you'd be back sooner or later :) In any case, it's nice to see you're still around and doing fine. I'm sure you'll amaze us with a new project sooner or later Thanks for sharing and hope to see you back soon!
Interesting find, I like finding treasures on the curb or in the alley, sometimes you can find some good items people throw away because they don't know what they have or how to repair them ,and some just wasteful. I have a Dell 24" monitor that developed lines similar, and I assumed it was a the LCD screen going bad, but they said it was most likely a faulty connection inside, which seems to be the problem. After it's on for a while they vanish or if I move the monitor around or tap on it they will vanish, which would indicate something not making contact inside, so you might just try cleaning all the connections first, could turn out to be an easy fix.
I brought it inside and ran it a while. It's just like you said. Lines vanished after running it a while. Tapping on the cabinet or flexing it causes them to go away or come back. Have not looked inside yet...
Got this at 4 views. Glad you are back. Was thinking of you when I was at the recent Kutztown PA radio flea mkt event. Saw lots of Bob Andersen type TVs for sale. 40s 50s BW.
Good to see you uploading again, more than likely a flatflex bonding issue between panel and vertical driver. Time to get in there with an insulated poker and start prodding! May be able to reflow with enough patience and precision. Good luck and 73.
Good to see you again Bob! I've been thinking about you and wondering when you would share something new with us again. Don't stay away so long this time darn it! :)
Glad to know you are ok always enjoy watching your videos. I know you are Very busy I am new to this hobby and I love it! I am recapping a 49' RCA 9t256 with great success but I do not have equipment to align this set are you available for hire? I live in The Quad Cities, Iowa about 3hrs from Chicago
My god I almost had a stroke seeing a new Bandersen video. Well we can all hope and hopes eternal..... Use a wall mount apparatus, no doubt that is why it is gone.
Hey Bob, That dry bar, when I saw it I thought the middle section was a roll of carpet padding or underlayment, lol. I have A 46" Samsung from 2012 myself. It's a smart tv but over the years the smart hub has lost more and more of it's functions as Samsung doesn't give it updates anymore because of it's age. It will still play on Amazon video but the youtube on it is gone which is a bummer. Also have a newer 32" Samsung and all it's smart functions still work including youtube. If you can't find a stand mount it was probably wall mounted and those wall mounts are pretty much almost universal. My pc's screen had those lines once upon a time as I think some windex got down behind the frame. Over time they went away on their own and here 3 years later I'm still using my 22" pc monitor I bought new in 2007.
Most likely a hot bar joint issue. They can often be fixed. Dave Jones (EEVBLOG) did a video some time ago on fixing this type of problem. Generally just try heating along the hot bar joints to try to re-bond them.
Was probably wall mounted, I hate the Samsung Plasma TVs. Check the Caps, ribbon cable like William Chow mentioned and if all else fails replace the tecon board.
Hey i got a new TV from the street too but it was not working. it's a 1080i 32" screen with cold cathode fluorecent tube backlight and it needed capacitor so, 30 minutes of work and 5USD for some caps...
I heard something about getting a glue gun and opening the front and cut some plastic pieces and glue them over whatevers causing the lines ..cause its touching plates its not suppose to touch....copper looking ones? ...hope this helps bro...when he press the plates in with his thumb...lines went away....so that's why he glues custom plastic cuts over the cause.
That’s most likely not electronic and a connection issue with you signal ribbon cable in the panel. Sometimes it can be shimmed and restore the connection and lines will go away. Try lightly tapping/banging on top and bottom in the area. If you can get it to go away, you know that’s it. Electronic problems in the T-Con board usually produce bigger problems. Norcal715 has several fantastic youtube videos dealing with these kind of faults.
You are correct! I brought it inside, let it run a while and a few lines disappeared. Tapping on the cabinet made them all go away. Ran it a few hours with no issues. Let it cool down and power it back up and even more lines appear. Tapping and flexing the cabinet would make the go away again. Time to take the back off!
@@bandersentv Fantastic! Just be careful, they are very delicate. Have had several neighbors sets in the shop with the same fault and 90% have been able to fix. Usually a little light heavy duty paper...just short of cardboard...will do the trick. Again, I would advise watching Norcal715, as he has some EXCELLENT videos on this very fault. Good luck...and glad your back.
I have two stands for Samsung's . They are never used and would most likely fit . I'm in Schaumburg and Travel downtown for work . I Can send you a few pictures and you can see if they would fit .

Glad to see you posting again Bob. You have taught me so much. You are a credit to vintage TV and radio repair guys.

Glad to see a video from you Bob! Hope you are well.

Thanks for sharing and hope to see you back soon!
Good to hear you're well Bob
Welcome back! :)
Glad to see you back Bob, hope you get back into doing some vintage TV's this winter.
Great to hear from you again Bob.. that's always the problem when the neighbour has a pool and you have a tree eh?

I have wondered about you. Moved and disappeared! Glad you are back!
glad to see you back

Glad to see you back, although I can understand how life gets in the way
Thanks for popping in Bob!
We missed you dude!

HI. No, sorry I don't have the time these days to take on projects. Are you sure it even needs one ?
Glad to see you're back

Got lines now ...two of them in my 2006 samsung flat tv

Bad LCD screen, Common on older Samsung/sony sets(both use samsung panels) Tab bond issue
Was probably wall mounted, I hate the Samsung Plasma TVs.

If it's not CRT or Plasma it's not allowed in my house
Thx for the update. I have to agree with the gents down below and say it looks like a bad panel.

i think sometimes you can fix the tape on top of the tv.... EEV Blog on YT has a fix with a trash can tv.
OMG
I have two stands for Samsung's . They are never used and would most likely fit . I'm in Schaumburg and Travel downtown for work . I Can send you a few pictures and you can see if they would fit .
Just adding my "we missed you" on TH-cam. Now please do find a proper vintage TV to repair :)
I promise I will when I find the time
May be a bad T-Con board. Relatively cheap component.
