Very good video my friend and helpful. I will do the same procedure with mine cause it freezes in the middle of a movie or at the end of it. Thank u for sharing.
I am so glad I found you! I followed your instruction s to the letter and cleaned my dvd player and it works like new! Thank you!! You have a new sub. I hope you make many more video's.
Been trying this with a highly intermittent and accessed the pot with a long screwdriver. Tried counterclockwise first. Each time the reponse did change. Not having the proper tool cause me to possibly damage the pot, now it wont read at all. I reccomend EXTREME caution using this procedure. It works but physical damage occurs very easily. I tried searching for a correct tool online but was unsuccessful. Any recomendations are welcomed.. or if i have to replace it entirely .. what cross reference is available ? Many different brands use the same laser mechanism so a donor unit would save a really nice machine, sacrificing a cheap one like the one in this video.
Hello. I have a koss dvd player, model #ks4122 that will not play or spin a dvd movie. I put a new laser in it and it still won't load a dvd, i have changed the spindle and sled motor, no change, i used a working sylvania dvd as a reference and readjusted the spindle height and the laser table height, this got the player to play approx. 3 cd's, but no dvd. The laser is similar to yours, with the 2 pots on the rear of the laser, below the ribbon cable, do you think the pots need adjustment, even with a new laser. I also used a bubble level and got the laser table level. Do you think it is worth it to try to adjust the pots, and which one is for the dvd, they are not marked, otherwise maybe i have a electronic problem with the mother board. Any help would be appreciated, if it is a electronic problem i can not find a service manual, any ideas, i would like to get it going again. Thanks
it's very annoying,my dvd player skipping and play random parts of the disc.I don't know if it's the disc fault or the dvd player.I clean the disc and it didn't skip on that part but another part.It is odd that turning that potentiometer can damage the laser,the laser should have had an current limiters such as ICs or mosfet.Anyway,it's great if brighter laser can solve it.
Hey electronicle, found your channel recently and love your content. I notice you post a more on “Rumble”, I guess to each their own but I didn’t really want to make an account their haha. Anyways, hope you post more here on RU-vid, and also was wondering how someone could go about sending stuff in for you to fix? I would pay of course if that’s an issue, or if you’re not interested that totally fine as well.
Hello and thanks! The stuff on Rumble was uploaded after it was originally uploaded to RU-vid. The only diff is the stuff uploaded to rumble was done more in bulk. So everything that's there is also on RU-vid. As far as sending things in, I'd love to do that but only have my home address currently. Don't really feel comfortable giving that out for people to send stuff. I am however looking into a PO box in the near future. Thanks again for your kind words.
@@Electronicle yes, get a PO Box. I use for 99% of my mail and delivers. Very safe can’t beat it! But it could be a little with delicate electronics. This is a little complicated for me I use used a memorex disc cleaner. So far so good.🙏🤞
I have a dvd but it cuts of then like ten minutes when I put it back on it will cut of again after five minutes. What help can I get in resolving this problem?
power shuts off or it stops reading the disc because if it stops reading the disc its either a dirty lense or the laser is on its way out. Very common. Doing what I showed can buy you some time but what you'll be doing is overdriving it and forcing it to be brighter. I have cd changers that have lasted years like this and ones that lasted only a few more plays. It all depends. If its the power that's shutting off, then its most likely an issue with the power supply. Unless you are able to diagnose power circuits, best option would be to replace it from a parts unit.
Ive got a Panasonic vhs dvd combo that on some discs freezes and goes pixalated. Would this method fix this issue? It doesn't do it on all dvds just now and again 🧐
Not sure. Depends on if it has problems reading discs. Since you say it reads others just fine, and its only a few that have problems, I wouldn't mess with it. Do other players also have problems with those discs?
Why not just get a dvd lens cleaner disc, not sure what you are doing here but I wouldn't advise anybody to take apart the player and clean with cotton buds!. You could do this with the big top loading VHS players but these players can be replaced for $20. It's just not worth the hassle
If you watch the video you'd see that cleaning it did nothing. The laser itself is on its way out, so by adjusting the current to the laser diode, it can shine a little bit brighter. So no, a dvd cleaning disc would do nothing.
Honestly Curtis DVD players were junk from day one. Not worth the effort for the average person when one can toss it in the dumpster and find much better, working DVD and Blu-ray players from quality brands at thrifts and flea markets for $20 or less all day long. And adjusting the pots only really buys the optical block a little extra time. Buying a new block for this player is overkill. Maybe if it was some expensive DVD/SACD/DVDA universal, not something that was dirt cheap and not meant to last to begin with.
Maybe they shouldn't be made so cheap from the component level up. That wasn't the case in the beginning of the computer age. Its all about bells and whistles and quality went to other lands.
