Blown lamps on two Teac P1250 CD players
I've never worked on one of these and can't find a free download of the service manual. So no exact answer for you, but here's a suggestion. Measure the supply voltage to the lamps where they connect to the PC board. I've found most receivers and other equipment to be 6 to 8 VAC, but these may be different. Then try to get one of the lamps out to see what style it is. It will probably turn out to be a submini lamp with pigtail leads soldered right onto the board behind the readout. (This probably means some fun getting to the display, but maybe this one was made for easy easy access.) Companies like MAT Electronics, MCM, Digi-Key and others have replacements available that should be close enough to the originals to work.
If there's room available, I'd recommend putting an LED in as a replacement. Once you know what the supply voltage is, you can figure the size resistor you need and find a place for it. I've done this on some other brands and types of equipment and it usually means you'll never have to deal with the display going dark again.
One other option is to purchase the service manual ($14.99 was the price I found at 3 online manual sites for download). Then you'd be able to find the exact part number and see if you can locate exact replacements. But that price will cover a bunch of LEDs.
The CD-P1250 skips while playing cds
There is no easy answer to this. I know that I have problems when I burn CDs in any format using my computers DVD burner. Fortunately I also have a regular CD burner which seems to do a much better job.
It may also be the CD player needs to be cleaned, seems that MP3 capable CD players are more sensitive when playing MP3 discs as opposed to regular CDs. There is really no other format that is widely supported (other than WMA) that will give you the capacity of a MP3.
Nad 502 CD will not recognise and play CD every time
HI.This will occur when the optical assembly becomes unstable. this ((Whole One Piece)), assembly incorporates the spin/load motor, optics housing /arm, tracking device and tracking rail. This is connected to the loading dock assembly. This 'NO Disc' or CD NOT PLAYABLE, code is the result of a failed or burned out lens, or misaligned loading mechanism. It is possible that you have a dirty lens cap. you can try using a cleaning disk in this case to confirm actual lens failure. if the cleaning doesn't restore normal reading capabilities, this will confirm my diagnosis.
You will need to have the optical assembly replaced in this case. once replaced, your unit will be able to read and track once more
Tray Sticking on CD Player
reoccurring tray problems are a paim. It mauy be a spot of oil or grease on the tray motorbelt, or the wrong belt fitted, and or dry failing bubricant to opening cam and sliders. Best approach is to strip and clean everything, lube only with white plastic grease, and sparingly. I use graphic powder on tray sliders, be careful not to get lubricants on drive belts. try next size down belt also, or be sure the belt fitted is 2.0 mm crosssectional area
