|
my barco c8 PWC has failed,I checked it and found that a power amplifier tube was broken, a fuse was broken, I replaced them,I reinstalled this PWC on the machine, The c8 was normal,You can see the image, but ,two minutes later, the machine automatically shut down again, I checked the PWC again and found that another power amplifier tube was burned,The reason is that there was no silica gel between the power amplification tube and the heat dissipation plate, which makes the tube burn. I replaced the power amplifier tube again,When I installed the PwC into the machine again , I pressed the power button on the rear of the machine,the power indicator light is on, and a row of detection lights are also on, but ,the machine cannot run with the remote control。 Why is that?
Thanks!
