Try a factory reset on the DL4 and see if it fixes the issue:
You can reset your pedal to the factory settings by powering it up with the A and D footswitches held down - the power is turned on and off on the modeler pedals by inserting a plug into the left mono input jack.

David, not sure if you read my post: I've tried the "factory reset" w/ no luck. I've also popped the chip out and popped it back in like folks have suggested w/ no luck.
I think its just that these pedals should are not solid and, as such, are an awful expensive gamble. I'm going to get a Vox Time Machine. It only does 1 type of delay (well, 2 actually) but it's bulletproof....My DL4 does 0 delays at present
You are absolutely entitled to your opinion and we respect any decision you make regarding your DL4 pedal.

lol... wow i must say i read through the whole post and was a bit surprised at line 6's lack of concern and solution to help remedy or compensate the issue.
note: i stumbled on the post because i just got my dl4 brand new in box and it didn't even come functioning. did a factory reset and atleast started getting some of the modeling to work and get different sounds. the main thing i notice that is off still though is on loop mode. it doesn't even make sense what its doing!
on hold waiting to speak to technical support now for exactly 20 minutes and 6 seconds. atleast i'm 1st caller in line now. started at 3rd inline. we'll see what they can even do. ---dishearting to pay 249$ and have to deal with this. i thought they claimed i needed this time to be making music?
Welcome to the World of Line6 Beaux. They'll just tell you to keep doing the "factory reset" which everyone knows doesn't fix this problem.
When their stuff works its great...but the fact that its a roll of the dice is unacceptable at this price point.
I replaced my dead DL4 w/ a Vox Joe Satriani Time Machine and couldn't be happier...It doesn't have all the bells & whistles of the DL4 but does have one thing DL4 doesn't: reliability. The DL4 does make a great doorstop tho.
@ jamiescale: I completely understand your position and respect it (as a fellow musician). As an employee for Line 6, I'm sorry you feel that way about your DL4, but I understand... it's nothing personal. I do hope your new delay serves you well in your musical endeavors: I mean it. All the best, man.
The "Factory Reset" is the only thing that an end user can try; if the issue stems from the internal software. Certain runtime glitches can be corrected by this action. This is really all we as Moderators can recommend on the Forums for users to try as far as troubleshooting goes.
If a Factory Reset does not change the symptoms, unfortunately the root cause of the issue is on the hardware level. At that point, there's really nothing else we can offer via typed instuction here that will correct the issue of your unit. This is why we direct users who have hardware issues to the nearest Authorized Line 6 Service Center (ASC) repair tech, because they will need to open the unit up, identify the component(s) that are problematic and replace them with new ones and re-test.
Two of our Moderators did offer the correct info previously, in the correct order of troubleshooting logic flow. What our company offers to users who've purchased a new DL4 from an Authorized Dealer is a 1-year Service Warranty period. If you unit experiences internal malfunctioning during that time frame, get the DL4 and a copy of your new product purchase receipt to the neareast ASC. At that point, the tech can diagnose and fix the hardware issue under warranty. If you're past the one year period, the manufacturer's warranty policy no longer applies and any potential diagnosis/repair costs are the customer's responsibility.
This is all covered in our company's Warranty Policy: http://line6.com/community/docs/DOC-4838
