I purchased the chipset replacement (V. 4.0) for my DC-1 from AVS (good deal!) a while back.
I intend to do the job muself but after reading some posts in another forum, I began to have second thoughts...

My call for help is from anyone who may have done the chip replacement themselves: what advice would you give me to arrive to a happy conclusion? I know that grounding one's self is paramount in importance, but are there other potentially problematic hidden issues that I should be aware of?
I have some knowledge of electronics...but not much about changing chips!

An alternative would be to have someone else do the job for me. Are there any dealers within the So. Cal. region who might be willing to help? I purchased the DC-1 from ebay some time back, so have no dealer to fall back or rely on.
I'll greatly appreciate any input given...

Frank have no fear..it is cake.

Open unit...Look for the matching chip.
When found, note which side the notch in the chip is on.
Remove old chip with included chip puller.
Take the new chip and insert it the same direction as the other...note the notch. (Also the socket is notched on one end.)

Do the same for the other chip of you have two.

Note, you may have to bend the pins of the chip inward slightly before trying to insert it into the socket. Best way to to this is to lay the chip on it's side on a table and apply slight force to move all the pins on one side of the chip inward at one time.

Hope this helps.

Do not be concerned, this is a very simple operation.

As Dave said, make sure to bend the pins on the IC slightly before inserting. Also, when you push the IC in go gently and insure no pins are being bent.

Reminds me of the old days when we had to insert DRAM chips on motherboards.
