Beomaster 8000, testing before buying

[Antoni Beksiak]

Hello everybody, new user here,

I have an opportunity to buy a Beomaster 8000 at reasonable price. Seller reports that there’s no radio reception (at all, but the display shows tuning frequency), some buttons don’t work, bass and treble adjustment doesn’t work, while the amp works as expected. Also I see some display segments are dead, but I understand it’s common and manageable.

I need to travel to see the device, I’d be happy to learn specific tests I can do to minimize risk. I’m not afraid of DIY repair.

Thanks in advance.

Welcome! If the amp works, that’s a good start. Before buying, test all inputs and outputs with speakers or headphones, check which buttons and controls fail, inspect the display, and note that dead segments are common but manageable. The lack of radio reception likely points to tuner or capacitor issues, which are often DIY-fixable. Overall, if you’re comfortable with minor repairs, it could be a worthwhile purchase.

@Geometry Dash Test every control and function carefully, especially the touch buttons, tuner with an antenna, and display, to see if the faults are isolated or part of a larger control board issue. If multiple functions like buttons, tone controls, and tuner are not working, assume a deeper electronic problem and only buy if you are prepared for complex repair or can negotiate a much lower price.

Could be as simple as a pulled cables inside.
Some cables are easily pulled inadvertently.

Some Beomasters have a too long bottom plate screw shorting a point under the tuner modules to chassis.
