.... At the other end (bottom) it has been pushed up and I can't fish it out with needle-nose pliers.
So....I decide to pull it all the way out and attach a stack of rare earth magnets wrapped in a piece of paper to stop them separating. Not the greatest photo, but the magnets are cylinders of about 5mm diameter.
My plan was to get them close to the bottom and then use the needle-nose pliers. It kind of worked, but the hole was a bit tight so they kept snagging and letting go. So I got some even bigger magnets and used them to attract the whole assembly out with some force. It worked.
Next, I taped the new, colorful, cable to the old one and pulled it all the way through. Success.
IMPORTANT CLEVER BIT: the strip had to be connected with the right wires in the right order, so it's important to check this when choosing where to cut. I was lucky to have a moment of clarity in my head before going ahead.
The strip was easy to cut with regular kitchen scissors.
I have a small problem to resolve. The remote control doesn't seem to do anything. On/off or colour change, nothing works. So I'm stuck with green at the moment.
Photo #1 shows the raised connectors.
Photo #2 shows the flat copper ones.
Photo #3 shows the double-sided tape peeled away to let the strip slide into the connector. If you're neat with this you can then fold the sticky bit back into the connector to help hold it all together and to fix the connector more securely to the mounting surface.
If it was mounted on a plate I’d take it out and see if I could push it from the back with a cotton bud. Bit annoyed there doesn’t seem to be an easy way of opening up the cabinet.
I don’t have a hot glue gun, might try a different type of tape later.
Horn distorting / crackling on an EV PA speaker. Before changing it I took a good look at it. Look carefully where I'm pointing to and you can see the solder joint has failed. Redid the joint with 60/40 and it's as good as gold again.
Computer can't boot because Harddrive won't spin up, customer in a panic. Quick check with the Fluke reveals the +12V line is shorted to ground. This is almost always a shorted cap and indeed it was the first cap I lifted ...
Then I didn't even bother replacing it as it's only there to remove ripple on longer cable runs. I just connected the drive to my machine and backed up the data before anything else could go wrong with the drive. What could have cost hundreds cost £70.
Digital desk with faulty chip which creates the voltage rails needed to run the input opamps and the phantom power.
I put the silver tape over the nearby sm resistors and caps because I don't want the hot air I'm gonna use disturbing them.
Here's an easy way to remove a package like this. Get some Chipquick ... this is a very low melting point type of solder. Smear it all over the pins, it will add thermal mass and allow you to heat all the pins at once so you can quickly remove the chip without ruining the pads.
So chip off and pads cleaned and ready for new chip
Have to wait for chip to be available now. I have brought one form Ebay but I just don't trust it to be genuine and you don't get many chances to get this kind of repair right.
just because you do, doesn't mean you should.
I wasn't really prepared for the situation, but I still took it home (very gingerly & with a fire extinguisher close to hand).
The bottom edge in this photo is the plastic case back & that white air bag is the battery FFS!
Despite the huge deformation, the screen hadn't cracked (god knows how) & the frame wasn't permanently bent.
Old battery is out & now resides in a fire/explosion resistant metal key-safe case until disposed of.
New battery is ordered, so we'll see if it has survived...
Google suggested I take the cover off and gently clean the lens with a cotton bud and ipa. It worked for a short time but the problem soon returned. I also checked the ribbon cable between the laser head unit and the main board and it was secure. It’s only about four years old and has been looked after. Is it toast?
Good info here though

Regarding the IPA, I'd suggest an organic cotton bud & something less American New England style, that like smell like fruit salad (sprinkled with weed), and taste like a shite fresh fruit punch.
Those bits really screw up a CD lens...
