My Yamaha MOX8 synthesizer recently developed two issues.
Firstly, after booting up, it operates as normal. However, after about 5 minutes, the sound starts to get distorted (broken up screeching sound) almost like putting it through a guitar distortion pedal. After a while, the distorted sounds will go away for a while and comes back. At times, the synthesizer will also freeze I need to power off and on again.
Secondly, when powering off and on again, there will be times where the synthesizer will freeze during the boot sequence (freezes at the MOX8 Opening Screen),...11-07-2024, 03:28 AM -
Hey all
I've been working on a 1984 Sanyo 27" color TV which had a smattering of bad caps in the video switching circuit. I found this oddball little 1uF 25V cap which looks to me like an early polymer, but I can't find concrete info proving it. I know Sanyo was a big player in early polymer cap development and this is the time period where they were just getting on the market, so I'm wondering if anyone has crusty old datasheets that could help identify it and determine if my suspicions are right? It has the same epoxy end seal and font/formatting as some old stock Os-Cons I've got laying...

Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but... -
hello everyone,
I don't normally do tv repairs but this is a case with my personal TV which got fried together with many other electronics in my house after a thunderstorm.
The TV is a Philips 65PUS8518/12 which had no power. I measured and concluded that the main board was probably fried through ethernet or hdmi. I found a board with same number 715GD328-M0F-B00-005Y (I had G) but from a 55PUS8518. The TV starts but the image is doubled, distorted. I need to set the panel code which is 016 according to the sticker on the back but I can not seem to do it.

Hey All,
I have a Sanyo DP5834 that did have an issue with the backlights, but I disassembled the unit and repaired the LED strips by resoldering all of the connectors. Now I've reassembled it and I have backlights and sound, but a grayish screen. I can tap on the screen and see that it's on, but no picture. All voltages seem to be correct on the power board.
Based on the LCD Flat panel TV troubleshooting guide by Bud Martin, I'm thinking the T-Con has failed because I'm getting 12v both into and out of FP1 on the T-Con. Am I on the right track?
Thanks,...
