Question about Toshiba 50H72 50" Rear Projection Television
We were watching the tv during a period of irregular power supply (during a storm). Seemed ok then suddenly went off. Now when we turn it on as normal, we hear the usual 'click', but have no picture, no sound, nothing. The front red light comes on as normal, but strangley it then altrernates between red and green every few minutes.
Manual says green light is something to do with the timer.
The convergence amps in those units consist of two Sanyo STK392-110 Ic's that get hot enough to fry eggs.. If your storm flexed voltages enough it could have easily shorted the amps and/or take either of two pico fuses in the 24v supply line to the amps... If you're not too tech savy this is one for a reliable shop and not and expensive fix. Two Sanyo Ics and a couple pico fuses should be more than $50.00 dollars and a couple hours of labor to put them in... While they're at it have them check the caps in the hyper module and for any ring cracks in the deflection circuit...
