Welcome to Apug!

Have you tried "001 Start" ?
 
Pulling the mains connector, waiting and plugging in again?
 
This piece of equipment relies on fairly complex (mostly) discrete electronics with especially the capacitors being a source of trouble. It's fairly likely that some have degraded, making the control electronics unstable/inoperable. Which, evidently, is very bad news. Some knowledge of electronics and a donor machine would come in handy at this point...
 
Yeah, someone with experience with this device can certainly be helpful.
The problem is mainly that this piece of equipment is based on 1980s era electronics design and components from that same era, which makes for the nasty combination of relatively complex electronics (often using hybrid analog-digital solutions for things such as pwm control, using analog oscillator circuitry which is sensitive to component degradation) and capacitors that just have a finite lifespan. Getting this to work may require a schematic, soldering iron and a healthy dose of patience & perseverance.
 
Hi, sorry my question is not entirely in line but I have the option to buy exactly the same model as yours (Durst HL 2501 AF). What will the fair price be? I am asking because I want to prepare for this purchase. Thanks in advance for your reply. Regards. Marcin
