hello!
I have an old Philips PM3232 oscilloscope with the following display trouble: very weak luminosity at the centre area of the crt, no possible setup of focus and intensity. the situation remain unchanged if the blanking signal (crt pin 4 through R831) is deconnected and or if the transistor TS801 removed!
any idea?
thanks
