thanks, man. with the hints regarding non soldered flat cables loose contact I was able to identify the problem on my 1066 unit with first 1-3 leds of channel 1 input/output indicator being constantly on. even with no signal at all. and also gate threshold leds behaving weird. btw, that thing about relays bridging input and output in the case of power outage is just awesome/
Nice video man! I have a DBX 1066 comp, it's overheating and was thinking on use a cooling pad, like it was a laptop (What do you think about that?) Anyway, now it seems better to me to install that little fans. The step that I didn't get is how you conect them to the power supply, is it too complicated? I have never fixed an electronic device. Should I just use the boring cooling pad?
A cooling pad might help you out if it's sound related, I am uncertain on how well it would move any air. If it's an audio issue it would be a matter of either tracking down the hot component or bad connection. The system board themselves did not seem to get all to warm so I would tend to think if it's not a display problem it's either a connection or one of the main regulators by the transformer. What are the symptoms you are experiencing?
@@Zenodilodon The comp works good, It sounds great but it gets heated in the area where the transformer is, then I have to turn it off for a moment while it gets cool again. I bought it used and I thought the heating was normal, now I'm not sure. I used to have a DBX266 and it did never get so warm
@@santiagopenaranda5922 They do get warm by the transformer, those are the main voltage regulators running, you may want to see about finding a piece of copper to fold and place under the regulators similar to what I did for the display. You will probably need to find rather decent sized plates for this. Other thoughts are possible to make vent holes by your transformer. That's the trouble with linear regulators is any power they don't allow through they end up resistivity dissipating as heat.
@@santiagopenaranda5922 My other thoughts are if you still have issues is to consider replacing the 2 regulators, sometimes they will fail over time despite the supposed built in thermal shut down safety. Even though the IC might be good still the expansion effects of the plastic cycling over time can cause stress on the wires, electron migration is also rare but happens as well. These are he first DBX systems I have worked on, I can't go all to specific with every little possible problem, good news is that regulators are dirt cheap.
You can replace the transformer with a split rail -/+ switch mode power supply or get another center tapped transformer with the same output. Strange that you would keep blowing fuses. I would say maybe replace the capacitors next to the transformer, they could possibly be failing.
Heyy bro! Me again! I was about buying the fans and I opened the compressor. I noticed that what's getting heated is not the transformer but the two capacitors, especialy at the bottom (It feels really heated if I lift up the compressor holding it from the bottom) and the metal sheet betwen the transformer and the capacitors. Now I'm don't really know what to do. Both capacitors look good although I also notice that the cable I'm using is a PC cable (125v) and the back of the compressor says 100-120v 50/60 Hz. Should I buy another cable? Replace the capacitors or install the fans? What do you think?
Well, that's no good at all, sounds like there has been some break down in the capacitors, you can replace them with any identically rated capacitor or slightly larger. They are just for smoothing so nothing really dependent on them, not for anything fancy like coupling or timing.

Glad to hear you got some troubles solved!
Hi! How did you solve this problem ?
Great video 😁

@@Zenodilodon I'll do that! Thank you very much!

The fuse on my dbx 1066 keeps blowing. Is there an easy way to replace the Transformer?
