    Yes Philips TV Chassis G110 BL.
    By now i think that the problem is in the +148 V circuit.
    There is no Voltage measured at pins 15 16 16 output of SOPS tranformer
    In the diagram 7802 is an smd transistor BC848 not for Chassis G110.
    7906 , 0902 are not referred.

CHECK ALSO IF YOUR TV's flyback or LOPT is damaged. check also its video output IC. ad other fusible resistors. carefully check for the capacitance of every capacitor connected specially at the High voltage section. don't forget also to check for cold solders

Is this model the GR9D Large signal board in Philips Projection TV? If so there are capacitors that need changing. Did you change 7906? 7802? 0902?

    you may have a short in the tv somewhere. I would take it in to a repair shop and let them give you a price to fix it. they charge around $50 to look it over. a new tv may be cheeper in the long run.

My xerox 7545 workcentre comes on, but it does not show the menu screen. it goes to fully on, but could not able to pick up menu screen.


Hello, The first thing you need to do it power down,unplug the workcentre and let sit for 2 mins. Plug back in and observe. If this doesn't work it will result in a call to your service provider and a field tech will have to trouble shoot the problem.
