Re: VX 724 black screen green light flashing
Not sure about the substitute transistors, but one reason the transistor is blown can be due to the bad tuning cap (brown cap next to the inverter transformer), one per transformer. You should take them out and measure the value and the resistance (it should show open with the meter set to highest Ohm range), if the cap is bad, you will damage your new transistors. The not working lamp transistor reading is bad, you should replace them in pair anyway.
