Today we'll take a look at a set of emergency lights with a couple of the LED modules that aren't as bright as they should be. The main issue is actually just a simple case of bad SMD caps (I know, I know. Most repairs the I do seem to be this same issue.), but simply by a minor case of ADD, I manage to compound the issue by blowing up a mosfet. I've seen many lights bite the dust in the past, regrettably most of them before I got into electronics, so I hope this video helps people that may be ready to sacrifice their faulty units to the trash.
As always, stay safe and have fun! And remember, if it's already broke, don't be afraid to rip it apart and try to fix it!

I definitely don't regret getting the HP, but I've been watching some of the Tek 4 channel CRT scopes and am sorely tempted to get one, but I've got other projects that are calling my name from their cardboard boxes. I my do an abbreviated shop tour and just show the hit points like a welders station, shear, press, waterjets, and whatever else seems interesting. Then again, it's all pretty interesting, even though I've been around it my whole life!

I have a Tek TDS620 which is what brought me to your channel a while ago....I like it but I don't kinda thing...but I don't have room for another on my bench due to all the other gear. I understand about other projects, Im swamped! :) Whatever you show Im sure it will be very cool! ~Jack, VEG

Yeah that 620 is a bench eater all by itself. The HP is great, sample rate sucks, but doesn't hurt for what I use it for, and I have my Rigol 1100E and Tek 465 to fill in where the HP lacks.

Agreed on its size! I thought I was doing good when I bought it but apparently not enough in depth research in regards to the bad caps, although mine works and appears they may have been changed, it still has a bad internal battery that is flat which causes the machine not to pass all tests, not sure how deep $$$$ I wanna go with repairs...but I did pay good money so I may entertain it just the same. I do like your Rigol & Tek. I can't remember, but are you a sub'd to me? ~Jack, VEG

@@VintageElectronicsGeek Yeah I subscribed to you. From what I remember changing the Dallas chip is pretty easy and doesn't cost much, the caveat is that recalibrating the scope takes an external computer with special software. I could be mistaken though, it's been awhile since I looked into it. If you haven't already, I would pull the acq board out of the scope and go over it with a microscope. There should be signs of either a recap, and if not, I would change them.
