Question about Audio & Video Receivers

Open Question

We have the Pioneer XD-Z54T and the CD player does not seem to be recognising some of our discs. We have tried the discs on another player and they are fine. Could the problem be the laser?

SOURCE: Pioneer PD-206 wont power up

Hi tfulton


Try disconnecting from the power and powering it up again to reset the unit.

If it still wont cooperate, the unit will have popped a IC protector in the power supply. Not an uncommon fault. The burnt disc you used may have pushed the tracking servos a little hard and a circuit protector has kicked it. Pop the lid off and look for a black 2 wire device about 4mm across that viewed from above has a D shape. Measure it with an ohm meter....It should read low ohms, if it does not... it has failed. It may be marked as ICPxx(from memory)

A fast fix we used for this is to grab the device and give it a 200 deg twist to short the legs together. Soemtimes(often) the body of the device will break off, just solder the legs left behind.

They have a habit of failingl with no reason, and shorting across them will not affect the operation of the unit, nor put it anything in jeopardy.

OR pull the board out... and replace the device, although I can tell you through experience, they may fail again.

Good luck, if you have any questions, just get back to
me here. :)

It must probably be a laser faulty, however it could also be derived from something that you can solve by cleaning.. The laser should be on only with cd inserted.

Pioneer DV535 Player


That sounds like a problem that needs professional service. The door may have jumped a gear, or there could be a circuit malfunction. At any rate, it's probably cheaper to buy a new DVD player. CD and DVD technology are quite precarious still, and I wouldn't expect more than a couple years service from most DVD players.

Hi Peter,
First thing to ask you to check is that the discs have been inserted into the cartridge the correct way... that is writing facing down. Check that first and let me know how you get on. Happy to work through it with you.

Sound like laser assy defected in any case you need a Technician from Pioneer or they are trained by Pioneer is very complicated to remove the laser and replace it you need an osilloscope to aligment a new laser and special disc to do that. It might not worth to repair it, the laser itself a bout $110.00 Aus

If this is a Pioneer CD player, you may need to do a grating adjustment. Do you have the service manual? What model number is this?

I may be able to help you more with this information.

The grating adjustment is needed on many different Pioneer CD players, mostly the older models. There is a smaill area on the pick up with a copper colored plate that must be moved just a little one way or the other. You put a very small flat head screwdriver in and move this copper plate just a little one way and then try again the other way if it doesn't work the first time.

There is a jig set up that Pioneer outlines in the service manual to do this properly. You need an O-scope as well to moniter a point on the jig. I have done this before without using the jig or O-scope, but it is more presise with these things being used.

This procedure needs to be done in the test mode so the disc is spinning constantly and then do the adjustment while watching the O-scope to know when the adjustment is at the proper position.

If this is a model that I have the service manual for, I can outline the procedure very well for you. But first I need to know the proper model number which I did not see in your post.

Let me know,

Dave

I have a Pioneer PD-M501 6 disc player and when i load a disc into one of the trays in the magizine it doesnt read it and it keeps changing disc trays, it skips it and said no disc, whats up?


Make sure you place the disk correctly in the caddy, (Upside down in the caddy). It seems backwards, but I had it do that, and I flipped the cd over, and it worked.

LG DR6921W DVD Recorder. Unit will not recognise DVD discs (Blank or commercially recorded)but will recognise and play audio CD's. Unit is 3 years old.


That is most common problem of DVD player recorder,when getting old cannot read DVD discs,only video cd and audio cd,sometimes does'nt read video cd also. The problem is in inside of the unit the DVD processor is defected already or maybe the solder is crack, need to resolder again or reheat the processor solder, or that processor change with a new one,so the performance will back again,good as new.The lense of that unit is good,i can assure that.
