When I turn it on it goes black and nothing - Eagle Cuda 300 Compact Fishfinder

Probably defective, you need to replace the screen or a cable inside of it https://www.sosav.co.uk/store/200-samsung

Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

you should re-install your RAM's. it'll be fixed.

thanks

press power screen reads digital television then the power light and stand by light turn on then screen goes black

The firmware to your TV might have corrupted. It should be upgraded.

I have the same radio and the same issue has any one figured it out ........

you may have a bad backlight have a qualified technician quote a repair and weigh price vs new technology replacement.

Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!
