morning all, have got a sanyo 26ld81. when switched on picture raster is completly red for 2 seconds then goes blue for 2 seconds then green for 2 seconds then back to red and the same thing repeats itself . the chassis has a 17pw22-4 power supply and a 17mb12-3 main board . it is the same chassis that is in a jvc lt-26dy8zj. any ideas , thanks
