Reminds me of the day my parents 22” Luxor tv from Sweden back in the year 76 lost the red colour. Technician replaced red resistor done a grey scale and convergence adjustment. It was a Toshiba picture tube and it had the best red colour of any tv back then.
Well that was a simple fault, it doesn't seem old at all. Maybe it sat in storage broken for a while. I would never mess with the yoke unless it was a real mess first. I learnt that lesson a long time ago. That game is not too far away from the original 80's systems.
Most CRT faults are pretty simple. These Panasonic sets have a very common 1/8w resistor that goes up and causes a pulsating picture. The odd cap that goes bad in vertical and the screen cap. As far as fuxing with the yoke, correct. Don't touch it unless absolutely necessary. It is opening a can of worms. Been there done that. 30 years ago had a goofball customer that was measuring crosshatch with protractor and i spent almost an entire day trying to make him happy. When I gave him the bill he just about shit. I said to him I was laid piece work and 100 charge paid me 40 bucks. I asked him how much he was paid for 5 hours work. He said 150, I said great the bull is 300! He just about shit, and I said well you said that 5 hours was worth 150, and for me to make 150 i have to charge you 400 as the shop is taking 60% and he should have thought about the cost before keeping me there half the day trying to make his tv acceptable to his standards. To top it off i got it looking great to his measurements with the back off and pulled away from the wall so i could set it up. He signed off on it, the back went on and the set pushed up against the wall. Earth magnetic field slightly different so what was acceptable 3 feet from the wall was unacceptable. In the end I make about 40 bucks for 5 hours work because he refused to pay more than 100 bucks. Every time he showed up with other equipment he was charged 2 to 3 times the price to repair. VCR came in with a blown fuse due to a wet cleaning tape jamming and it required a power supply rebuild. On top of that the boss gave me shit for taking so long trying to fix a non existing problem for a picky customer.
@@12voltvids Unfortunately, you are right. I tought myself that on this last RGB modded set I tried to sell lol. It finally sold, but I spent more time getting haggled for my price than it was worth.
I can actually see the dot crawl on the camera capture. Old CRTs do have a certain charm to them. I can see why people like to play classic video games on them. I personally just don't have the room for that. It's funny that we ended up collected all these old CRT TVs as spares back when people were just throwing them out. I could probably make a lot of money auctioning them off on eBay. The shipping costs would be enormous, and I don't have the moral decline to just put them on a mailing bag like a lot of crap that is shipped today. Double boxing for sure.
Even then they get trashed. I sold a monitor 15 years ago for 25.00. I put it in a TV box with styrofoam packing exactly how new TV's where packed. Shipping cost was 140. When it go to the destination it was smashed. Buyer demanded money back including shipping. Told him to file a claim with cavafa post. They broke ir.
I always check for flaring by turning the brightness contrast and color all the way up. It can flare a bit with certain colors when the tint is red all the way or green all the way.
I'm a total newbie and had no idea that loss of base voltage could lead to the output voltage being too high and not displaying color. I have a scrapyard find 21" panasonic set that is missing one color and has too high voltage on one of the cathodes. I assumed it was a worn tube causing too high resistance and making the voltage go up but I think now I have to try checking the base voltages. Thanks a lot!
It was loss of connectivity of the collector on output. The output travsustors pull the kathodes towards ground. 160v will have the kathode at full cut off. As the transistor conducts it pulls the voltage lower and the tube goes into conduction. The lower the voltage the more beam current the brighter the picture.
Small TVs were built to a cost and mass produced so cost cutting was the norm. Slight errors in geometry was to be expected with no pincushion correction. Still a nice example for gaming. I do miss the tv trade when you could do fifty sets a week I was young and keen in those days
@@pyeltd.5457 sure you did. When I worked for Sony we were modding all the betamax machine that needed updates before they could be sold. There was 3 of us on the team. One guy unboxed and disassembled / reassembled and handed to the 2 techs myself and another guy. One if us would pull the bad caps and replace them. We had a template and power solder vac so it was fast. The other guy changed the rewind pullys to metal ones. It would go from one bench to the other and back to the guy that was opening and closing them up. 4 an hour was what was expected. If we really hustled it was 5 an hour. 30 was the max and that was really moving.
Good thing you're not addicted to video games, or else you'd get nothing done!. Looks like fun! I never had those games personally. I played sometimes in arcades and a friend's house. P.S., I wasn't any good. Lol. Duck Hunt was really aggravating. That stupid dog laughing at me. 😭
Video games are the most useless thing invented. My 23 year old is addicted. He won't even drive just go to work then comes home and gets lost in his fantasy world. No friends to hang out with other than the losers he hangs out with in the game rooms. Spends all his money buying crap online. I hate video games. They have ruined many lives. Kids get addicted and it is no different than gambling addiction or drug addiction. No I am not a gamer, I have a life and enjoy living it. Now excuse me while i throw my leg over my Harley Davidson and go for a nice little ride.
Yeah most of those controllers (like factory atari) never worked that great as they aged. I preferred the slick stick-I think that's what it was called. It used a tire valve stem for the joystick and the internals were not push pads. Instead it was a metal ball in a square chamber with metal tabs on each of the 4 sides-worked very well all things considered. Galaga was always a fun game, but I preferred Hemorrhoids-LMBO!!!!!
12:41 i heard people saying the newer games 7th and 8th generation looks good on a crt set. I bet the ps5 and the other 9th generation consoles may or may not have the composite port.
I don't know why, but in the U.S. we call those 13 inch. Before I watch the video, I'll say the CRT is bad. Had this problem in the past and replacing the CRT solved the problem.
13" picture, 14" tube size. In Canada they quoted the size of the tube not the picture. It all started back in the 60s when one manufacture started using the tube size to fool buyers into thinking their tv was bigger. Once one company got away with it everyone else jumped on board. I remember the boxes on many new sets. 25" TV (27" in Canada)
@@12voltvids CRT sizes were quoted as the diagonal measurement because REALLY early CRTs has a round screen, on which was generated a rectangular image. Thus, the diameter of a round CRT = the diagonal measurement of the image, which continued when the CRTs were produced with a rectangle screen. With rectangular CRTs, as stated before, some markets, such as the US, quoted the measurement of the actual image size while others, such as Europe, continued to quote the size of the glass envelope. In Europe, and possibly elsewhere, the introduction of the FST CRT, (Flatter, Squarer Tube), heralded a change to quoting the size of the image area.
