I want to take this opportunity, to thank you for the few TV videos you have done. I was able to fix two CCFL HD TVs by using your technics. Since I watched the few LED TV ones, I only try to fix CCFL sets with still good backlight. One was a Toshiba with VESTEL electronics and the other a 2008 Samsung set. Both are just aged and suffered some dry caps, the Toshiba had a blown fuse too. But I was not able to find any shorts in the PSU and since I replaced the caps it still works fine. The Toshiba is mine it was gifted to me. The Samsung is from a elderly lady above 90 years of age and I am pretty sure the set will outlive her now.
Had a brand new 80386 in 1992. Turned it on, it worked for about and hour then froze. Unplug, let cool, repeat, unplug, let cool, repeat. Took it out of the cabinet and found that one of the ICs had crept from its socket. Cleaned the contacts and pushed it back in. Worked perfectly. Checked the other sockets. It was the board heating up and causing the IC to lose contact at one leg. So I always check socketed IC’s, then caps, then IC solder joints. So the logic behind your ground screw makes sense, as the board heats it warps and lifts a ground contact. Cheers and thanks for the video!
On one of the old-school Apple computers (probably some ][ variant) the official troubleshooting steps included picking it up and dropping it a few inches onto the table to improve the socket connections.
I had a stereo long ago that would screech randomly so loud it went full P-P on the outputs and fried a zobel network in it. Of course it was class D so I suspected somewhere inside it was a star ground. Wouldn't you know one of the damn ground screws were loose just enough and going to part of the circuit that was grounded elsewhere but it really needed that frame ground for a low resistance path beyond the PCB. Scared the hell out of my cat when it would do it, he'd go running like his life depended on it because most of the screech was beyond my hearing! Love your channel. Been a fan for a while now. Watching you repair stuff and talk about stories is far more entertaining than anything on TV these days to me :)
@@12voltvids I watch old classic shows here. i have many on dvd and stream other shows on free apps with Roku tv. i did find a google tv box in recycling i have that here. i reset it so now i might try register it and see what that does. it came with a harmony remote and keyboard. i just got lucky looking for stuff along side the road. as i like picking up vCRs just to get what i can going again. then just use them here. as no one around here buys anything like that.
They are now. but decades ago they had good CRT sets. i had one run with no issues for years. it died last year finally. so now i got flatscreen vizio tv's. i have good luck with those atleast. as one is going on 10 years old. thats a CFL set. my smart tv not sure how long that will run. but older crt sets ran a long time.
@@randymoyer5351 Yeah, RCA did have good CRT sets before the company was broken up by GE and its pieces sold off. Under Thomson, RCA branded picture tubes continued to be good, but the Thomson electronics used for making RCA brand TV sets could have peculiar problems, particularly throughout the 1990s.
You need to know the right words to tell when they ask you if you can fix their TV. Especially that they know you can fix anything. No ma'am, it's not worth fixing, you better buy a new one for 250, and give this one to me. Ahh, this never works for me. They get suspicios right away. So you definitely know something that I don't.
Nothing is worse than a fault that you can't find a definate cause for. Your customers quickly lose confidence in your abiltites because they don't understand how difficult these are to pin down. Looks like this one is fixed, i hope it stays that way.
They sure don’t make tvs the way they used to. Lol. It’s a good and bad thing. I grew up with an rca floor model that we had from about 1988 until not sure as when it stopped working my mother just sat a new tv on top of it. Ha ha ha. I’m glad a 20” tv no longer weighs 60lbs.
Curious fault with an interesting solution. I think what happened is that the ground voltage crept up after turning it on when it didn't have proper contact.
I hate these type of troubles. You never know if you got it or not. Everything points to the loose ground however. It could however have been a cracked bga on the main processor and removing the board and reinstalling fixed it. No way to know unless it faults again.
Halfway through the vid: Perhaps some kind of lockout control purposefully-supposed (but accidentally) set? FIrmware update and/or reset. Maybe has nothing to do with final solution but that's where I'm at before you put it back together.
There is nothing in it, because it's simple and older TV. Check out some modern high-end Samsung/LG/Sony Q-LED or OLED TV. Absolutely different world. My LG OLED evo C4 has like 3 or 4 boards. I mean tech went long way. You can't compare the old plasma days with 5-6 boards. Now you can achieve similar if not better results with tech. The small chip can contain everything from the signal stuff to the T-CON management.
I have several tvs for the lunch room. I have a larger 46" set that the hdmi has no sound but component works fine and the TV box has component output. Will likely take that one up. Don't know how much longer we will have service at work. It's on a dsl fed line and copper is being retired. Will have to talk to the boss and see if I can get a work order to pull in fiber. The olt and splitter and for that matter a test ont is like 30 feet away or perhaps a dslam will be left running. Probably not will have to convert to fiber. Or they could just kill the TV service. I told the boss that wifi is used there too when we are working at the office. (Its a telephone central office) the phone switch is being decommissioned as everything is fiber now. All the fiber for the community is in there as is all the cell tower switching. I wish I could share pictures but I can't. At least not while I am still working three.
I got a old but working Samsung LE40R87BD LCD TV the other day. I just tried up the HDMI cable and broke the cable lucky the 4070 is ok the cables are always to short.
Not really. I don't get many cassette decks to repair. I have several working cassette decks up for sale and no bites, which gives you an idea on how popular they are these days. People keep telling me how much they go for. Not around here they don't.
I was going to say if you couldn't fix it might make a good security camera monitor. who would have thought a loose Gnd screw would make the controls not work. seems like it has a nice picture. I'm guessing it's a 40 inch
Hey there I have a JVC SVHS editor type recorder. Since its quite old...do you have test equipment to see how well it runs in terms of video quality. As old capacitors maybe gone... would you be able to find out? I can have it shipped or dropped off.
A friend of mine had a set similar to this. none the buttons would work nor the remote. we checked everything it was ok. so just disconnected the panel of buttons from the board then it worked fine for the remote. its still working like that. i think maybe something went wrong on the board that has the micro switches on it. like one might of gone bad and shorting that board. we never changed them as he said as long as the remote worked on it might as well leave well enough alone. he still has the set. that wa a strange one as well. as sensor is on its own board. so unplugging the power board that has the switches on it didn't affect that part. .
I have had that too in the past but this was different. Would work for a minute then stop, unplug and it would work again for s minute. Still working as if today as I just tried it.
2 minutes in and to me it is obviously a thermal condition as the problem. Well, maybe that's too strong of wording. Let's see or shall I say, let me see. On with the vid. :)
Rca is just a brand name of Thompson so yes tcl probably made it. There are only a few that make their own stuff. Sony, LG and Samsung. The rest are made by tcl, Haier, ect.
It was 250 and lasted 8 years. Back in the 80s you paid 1299 for a 27" TV that needed a 150 repair before it was 5 years old and another 15p repair every few years.

@@12voltvids It is kind of hard to come across one of those for me. In Germany they never got that popular
see if u can inherit the second set too
@@12voltvids Can't beat them, but they were short-lived. 🤒

RCA = Really Crappy Apparatus
But in this case, this TV is a worthy successor to that DLP RPTV in your work's break room.

And Dave, the fact that in the US, parts in stock are subject to a tax, plus you have to do an inventory for a once a year status claim.

Put that TV on your PLASMA place to work with all the video equipment you repair to not have that interferences you always have.

Its a clone of a solderpult

RCA is not as good like they were in the early years
TVs are unfixable these days.
You got it. Why do you think I refuse them. Only if they are mine will I attempt and even then many up in the trash.
Remibds me Plasma sets screw that cause ground issue's and board damage
Lots of those especially panasonic. They came out with a parts kit that included new screws with lock washers.
RCA. The worst name in TVs.
40 years ago they were too. Nothing changes.
Modern TV’s are junk
