hello i have a sony t303, my problem is that when i switch on the phone the lcd is working for a blink of a second and then all returns to black.Seems like the backlight of the lcd is not working.I ve tryed everything i bought 2 new lcds and they do the same thing,i changed the ribbon cable that connects the open part of the phone with the pcb mainboard and still the same?Any ideas whats wrong??
Seems like when it switching on something short circuits and then all fails.
