Allen & Heath Allen Heath GL2400 32 Live Sound Console - Answered Questions & Fixed issues
I Have a GL2400 Allen
I will ask a question: Did you remember to power ALL inteconnected equipment from the SAME and I do meanALL and SAME receptacle or power conditioner module? If you powered your stuff from several receptacles in a large venue, likely ground system bounce has caused damage. I don't know what you mean by "dont get any signal in."... explain that... There are tests to run to isolate the problem but if you got hit with ground bounce transients you could have major damage. That is a big board for an outside venue so you might describe what you had configured from mics, etc. to speakers. ALL professionals know to run power back from where their amps are to the mixer alongside the snake. I will give you points for carrying a spare... ALWAYS a good plan as electronics DO fail and of course at the worst time.
Hello,

Above is your user manual below is a service and repair manual.

Indeed i would suspect something around your Final Output semiconductors, and any associated resistors?
You really must obtain a service manual, here there are the troubleshooting steps required to isolate and hopefully allow repair of your unit.
Look for any discolored components etc, check if any are overly hot... use a temperature probe on suspected components. Freeze spray may also be useful in diagnosis.
Use your eyes & nose to isolate the bad burnt overheated components, I sometimes use a straw up a nostril and selectively go over suspect parts, and "Sniff" to try and detect the overheated smell... it works.

No or very little sound from Fender passport
Depending on the model, there are four around that date, it could be the insert jacks are tarnished reducing the signal flow between the pre amp stage and digital power amplifier. It could be the power amplifier has failed. It could even be customer error in wiring.
This assumes there is the correct level of signal entering the input sockets of course.

Breaking Roland RD 600 hammers
The Roland RD-600 is a digital piano, and its hammer action mechanism is designed to simulate the feel of an acoustic piano. The hammers in digital pianos like the RD-600 are typically made of materials like plastic or a combination of materials to replicate the weighted feel of acoustic piano keys.
The breaking of hammers in a digital piano is not a common issue, and it's not typically related to the age of the instrument alone. Several factors could contribute to the breakage of hammers, and it's essential to consider the following possibilities:
- Excessive Force: If the keys are played with excessive force or if there's any physical damage to the instrument, it could lead to the breakage of hammers.
- Material Quality: The quality of materials used in the construction of the hammers can impact their durability. If the hammers are made from subpar materials, they may be more prone to breaking.
- Manufacturing Defects: In some cases, there could be manufacturing defects that make the hammers more susceptible to breakage.
- Maintenance: Lack of proper maintenance, such as cleaning and regular inspection, may contribute to the wear and tear of components, including hammers.
If you've observed a pattern of hammers breaking with regularity, it might be worth investigating the specific cause. If it's due to excessive force or physical damage, adjusting playing habits and taking care during transport can help mitigate the issue.
As for whether it's worth purchasing new hammers from Roland, it depends on the extent of the damage and the overall condition of the instrument. If the RD-600 is in good condition otherwise and you enjoy playing it, replacing the hammers could be a reasonable option. However, you may want to assess the cost of replacement hammers compared to the overall value of the instrument, factoring in the cost of a used RD-600 and any potential future maintenance needs.

Squeaky bass pedal board Roland PK5
I know this post is super old, but it was one of the first hits I had when searching this problem, so I'll post it here in the hopes that it will help someone. I found that I had to get under the cover, and clean/lube the plastic post on the assembly that pushes the button on the circuit board. It's a plastic post that slides in a plastic slot. I think it just gets contaminated with dust and that is the main cause. Philips screwdriver gets you under the cover and removes the two screws that hold that assembly together. Obviously be really careful to not break the plastic post. Looks like the wrong kind of force would snap it very easily. I used Deoxit Fader Lube, sprayed on a rag, and wiped the surfaces where the plastic parts touch. Put it back together and worked the pedal a few times, no squeak.
