The foot pedal pneumatic valve leaked at the higher end of the operating pressure range at which we needed to operate which was noisy and wasted energy.
A small module from a large reflow oven for cooling fans control was sent in for repair. The output was not operating. No datasheet or schematic was available.
A customer reported problems with the LCD on an automated stencil printer, which would take around 30 minutes to start displaying correct information.
Data recovery made possible by swapping flash memory IC from a damaged controller PCB onto an identical working PCB from a donor drive.
The chain drive had a snapped chain sprocket on the drive gearbox. The sprocket was split along the keyway and bent open.
The value of some 100 Ohms steps was actually 200 Ohms. Replacement resistance wire was hard to obtain and normal magnet wire would be awkward to work with.
An old portable ultrasound scanner was acquired semi-working. The first time it was operated it began to smoke within a few minutes.
The Rifa safety capacitors were all showing signs of cracking. Some of the electrolytic capacitors had leaked.
The BNC connector tip pulled out of the connector when unplugging. The solder joint had snapped where the conductor joined the contact.
Broken LEDs and ICs in Gloshine outdoor display modules created blank pixels and missing areas of the display.
The Rifa safety capacitors were all showing signs of cracking. Some of the electrolytic capacitors had leaked.
A Marconi Instruments 2019A RF signal generator needed repair. It displayed an error code “—24—” instead of the frequency setting on the first LCD.
Microwave frequency counter would not power up correctly. The high range was not working correctly.
The Rifa safety capacitors were all showing signs of cracking. Some of the electrolytic capacitors had leaked.
Mazda Bose car audio amplifier was making a loud “machine gun sound” from the speakers.
Programmable PSU would not start up reliably and would not operate under full load.
Marconi 2955A Radio Communications Test Set fails self tests and would not receive FM or PM signals.
This spectrum analyser was not working at all on the 100 kHz to 2 GHz range. The input attenuator was also not operating correctly.
This microwave amplifier would not come out of the standby state and needed several problems correcting before it would function correctly. This device uses an interesting mixture of vacuum tubes, semiconductors and a travelling wave tube.
This TTI TCB-1100 CB radio wouldn’t power off when the volume/power control was in the off position.
Radio communications analyser shows incorrect frequency on spectrum analyser, changing span setting made display shift in frequency.
