HHB 850 CD Burner - lockup problem

The unit locks up midway through finalization of a CD. Turning the burner off and restart brings the machine to exact same point. I had to take the unit apart to remove the CD.  Even with the CD removed the unit fails to return to normal/ready status.  Is there any factory restart technique?

    Bad CDR stuck in HHB cdr850 in TOC finalization mode. DO I have to ship it for repair? I tried pressing the menu and auto buttons for several seconds. Thank you.

I did find out how to do the manual eject, for a stuck cd. Open up the machine, looking at the front/top, on the lower left side of the cd transport there is a white plastic gear that can be turned with your finger, ejecting the cd.

I just encountered this same problem. i was able to get the cd out by following barbhirsch's advice (see solution #2). after closing the cd tray, and powering the machine back up, however, it was still *stuck* halfway through the finalization process. however, i did come up with a solution...

1. with the power off, remove the disc per barbhirsch's instructions.

2. leaving the cd tray in the open position, turn the power back on. upon powering up, my hhb automatically started looking for a new cd, and the problem was solved.

hope this is of help to anyone who is having problems with this!

I spoke with the HHB factory. they said you cannot use high speed media. You need to use 32x or slower. I too have seen this trouble.

The 850 has a test mode accessed by shorting a jumper on the display board,but you could try the 830 method - hold in the menu/delete and the auto/manual keys for longer than 5 seconds. Careful, don't adjust anything, just power off to exit test menu.

    I can provide you guys with the service manual that goes through the test mode sequence but it isn't as easy as with an 830 - you need to do a bit of soldering to reset it. Anyone know how I can upload to this site?

My top thread is getting tangled up in the bobbin case area, even when hand turning the wheel with the bobbin and case removed; trying to fix a serious tension problem.

First, install a brand new needle.

Remove the thread from the machine. ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct and that the bobbin is loaded and threaded correctly. Set the top tension to the midway point--you'll probably need to tweak the tension for your particular machine.

Bring the bobbin thread to the top of the fabric (manually with the handwheel). Then gently hold both thread tails in your left hand while you begin to slowly take the first couple of stitches.

If you are still getting thread barfs in the bobbin area, your machine may be out of time. Search for sewing machine timing or take it for service.

Be sure to install a brand new needle. Needles should be changed frequently as bent/damaged,worn needles will cause problems with the stitching quality.

Remove all the thread.

ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct.

Set the upper tension to the midway point between high & low number.

Bring the bobbin thread up before beginning to stitch.

If it still will not bring up the thread, then it most likely has a timing issue. Take it for service.

How do i set the the cotton tensions as there is no numbers to go by

Start out with it set at the midway point between the two ends. That is the basic starting point, but tweaking will most likely be required to get it exactly where it looks best.

Need diagram for threading

Search the internet for:

Make + Model + "threading"

The factory standard tension is the midway point between the high & low number. Then tweak the tension from there. Tighten to pull the lower thread higher in the fabric, Loosen to bring the top thread lower in the fabric.

Search the internet for "sewing machine tension"

Unfortunately it's pretty much impossible to get a recording to sound like anything produced commercially these days without using lots of compression. Your burned CD problems might be the result of a faulty burner on your DP01-FX/CD. I have a 2488 and I still export all my mastered songs as wav files and burn them onto disc using my PC just because of the flexibility on the PC and you can control settings better which can cause disc burning problems (not to mention that the burner is newer and faster on my PC).

If you don't want to work on a PC you could look into replacing the burner in your Tascam. It is similar to replacing a PC's burner and the either the Tascam site and/or the Tascam Forum should be able to provide you with the specs and a list of compatible CD burners.

To get the final product to sound louder you could invest in an external compressor (a good used one should run you less than $100). You'll have to use the DP01's send loops to route a bounce of the stereo mix out to the compressor and then route the result back into the DP01 inputs and record on a couple of free tracks.

Hope this helps.

LG GSA-4167B DVD Writer... PC restarts whenever any CD is inserted

What is happening is that the dvdrom firmware or the laser is failing and cannot read the disc; and because the pc is using all the system resources trying to do so; it appears that you cannot get anything to run, making it seem as if the hard drive is faulty also, though not the case. You will need to replace the drive if this is a common occurance, as the life of a dvd drive nowadays dependant on use is aprox 2 years, because as the prices come down so does the quality of the laser required to burn and read discs.
