Hello all, I have here a real Toshiba no vestel junk ! The issue today is that the backlight fires on but then shuts down. Normally I would suspect that there is a failing Ccfl lamp however upon hocking up two sets of know good lamps the fault is still the same the known good lamps all start fine then go off.
Upon checking the "lamp error pin" its 3.3v at all times should it be ? The "blon" and "dim" voltages are all fine. This tv has the inverter built onto the Psu I have checked the Mosfets that drive the inverter and they are good so what could cause this any help is much appreciated thank you.
