- Repairing a faulty CD player in a Philips AZ1003 Boom Box.
A fairly simple repair in diagnosing a faulty laser diode, then replacing the whole optical block. But the repair was complicated by differing versions of the optical block, which lead me to buying the wrong one.
Finding the correct version by identifying the number of pins in the ribbon connector was the answer.
Miracle! Same model, CD not reading. Cleaned lens--no response. Optical assembly moving and tracking but no observed laser output. Decision: Scrap as beyond economic repair (even at £5 for a replacement not worth the time for a machine with a resale value around £10-15). Revised option: blow some air. Result: working perfectly.
Now I suppose I'll need to reconsider the other dozen machines in the junk pile. . .
Even after over 40 years in electronic maintenance (albeit not in consumer equipment) there are still lessons to be learnt!
Fab fix, well done. :-)
This is amazing. Thanks for the 15/16 pin tip!
Glad it was helpful!
I'm very happy too see many people are getting use out of the low 2000 boomboxes
Me too, especially when they break and I can fix them.
Very tutorial video! I always enjoy your videos! Glad you fixed this one nicely done!
Thank you! Cheers!
Other very good video! Congratulations Mr. Chase, I wait for the next one!
Thanks for the compliment, I'm working on more.
Wow thanks for making this video same issue is with my Philips boom box also Az1030. Same problem with my SONY CFO-F10. Who knows if these companies over looked these issues before they put their products on the market??
I am in NY....enjoyed your video👍
I am actually sending this radio to my brother in PA. I will include this link.
I SUBSCRIBED 😀👌
Thanks for sharing
Dear Sir,
Thank you very much for this tutorial. It is extremely helpful. I have the exact same problem. However, when I opened the inside, I realised that one of the two sockets connected to the CD unit is directly soldered to the circuit board (at 14:51 in the video). How is such a thing possible, and do I have to cut the wire completely and solder a new socket to be able to use it after changing the unit?
I cannot say I've ever come across one of these Philips units with the ribbon cable soldered onto the PCB for the laser but that does not mean it's not true. Much older CD optical blocks did use ribbons that were soldered at least one end, the other should terminate in a Plug or ZIF connector. The service manual should show an exploded view with the connectors and the part number for the block could be searched for which will result in the correct item.
I have a AZ1050/05. It seems to to be playing cds intermittently...not the cd and have cleaned the lens . Is this likely to be the same problem?
Probably, can only guess. Try blowing the dust out with compressed air.
Hi Mr. Chase, a very clear video tutorial for this interesting device.
I am now trying to open a Philips AZ1065 boombox, in very good general conditions, no dirty or dust, but it doesn't run, nor with AC 220V, nor with batteries (9V).
So I have removed all the screws from the two plastic shells to open the boombox, but I cannot succeed.
Must I use a screwdriver (slowly) to separate the two halves of my device?
I would be so grateful to you for a kind reply, many thanks.
Hi Bruno, I would look for hidden screws. Possibly underneath rubber feet stuck on the bottom.
You can download the manual from here which shows how to dismantle the unit. elektrotanya.com/showresult?what=Philips%20az1065&kategoria=&kat2=all
@@ChasLarge Hi Mr. Chase, I have found 2 little screws inside the device, now the 2 halves of the Philips AZ 1065 are separated and I can try to find the damage.
Thank you so much for you useful kindness (also for the link).
Wow, this explains a lot. I have a lime green sound machine Phillip's and had the same issue. Did the lens clean with alcohol and q-tips and nothing. This looks very tedious and I'm afraid I'd mess something up replacing the optical block. I wish they had people like you in my area of Phoenix, Arizona. Sadly not many actual CD players are around anymore and there aren't many real repair shops left. Those that are around charge simple repairs for as much as the item costed when it was brand new.
Hi Brian, I'd volunteer to fix your unit for you but the shipping to and fro the UK would outweigh the benefit of the fix. Repair shops began to go out of business in the mid 90s. I closed shop when people could buy a new VCR for the equivalent cost of repairing their old machine. I used to charge £20 + parts + tax for a basic repair, and now folk balk at the same costs, even though £20 is worth approximately %50 if it's value back in the 90s.
How to get the power cable
Try ebay?
Hello I really appreciated your video. I have a Sony cfd-760 and my problem is the laser seems to have trouble and skips when I turn up the bass and volume; especially on the the first couple tracks (but on all tracks). I did the air spray and tried cleaning the lens to no avail. Any suggestions besides replacing the laser block as you did on the boom box in your video? Your reply in much appreciated.
Hi David, well you've carried out the basics, well done. The skipping, especially when the BASS is turned up, would tend to point to a loss of the signal back to the signal processor due to vibration, which could either be poor focus or poor tracking. Most modern CRs have a built in buffer for the data to overcome physical shock losing the track, so the extra BASS would appear to be causing more shock than the buffer can handle. A check of the RF waveform from the processor would show how good the signal is. You can download a service manual from here:
elektrotanya.com/sony_cfd-750l_cfd-760l_cd_radio_cassette_sm.pdf/download.html#dl
See page 14 for the RF waveform check.
I would check the height of the turntable - see page 3, as sometimes these can be pushed down by inadvertent excessive force when putting the disc in.
You could put the unit into SERVICE MODE - see page 13 and check the CD adjustments signals, don't adjust unless necessary and you are confident. Mark the pot positions before making any adjustments so you can put them back.
Hope this helps. If you want me to have a look at the unit for you, please contact me via my email -> Channel Page -> About.
Thank you much for your reply and I will try what you have explained. Not sure it would be cost effective to have you check it out since I live in California, however, thank you for your offer and extended info. Your the best!!!
@@davidnavarro6115 Happy to help. Maybe you'll find another US based UA-cam repairer who could help. Sorry I can't. Good luck.
Hello, great video! Do you know which one of the screws is the one that can calibrate the lens. Thank you.
Thanks for the appreciation. According to the service manual, there are no adjustments for the CD mechanism or circuitry, all adjustments would have been made in the factory using computer controlled changes to the firmware.
There is a LASER POWER adjustment potentiometer on the Optical Block PCB but this should NEVER be adjusted without using a LASER power meter and suitable eye protection. If the CD is not playing correctly, clean the optical block with short bursts of compressed air and apply molyslip grease to the sled drive rail. If that fails, replace the optical block.
@@ChasLarge thank you very much for your help!
what exactly did he do before putting the ribbon cable on? he said he’s remove something, but i cant quite catch it
If you're eferring to my actions at 41:22 in the video, I was removing the shorting link on the PCB which is put there by the manufacturer of the replacement part, to protect the laser from static damage. If you don't remove it, he laser will not light. It's just a blob of solder across two points on the laser PCB.
Sir do u think this is the common defect on Cd player boombox ..lense replacement?
Yes. CD lasers fail due to age, so if there is no light visible it could be the laser.
Please az 1565 boom box ,no audio ...
