KP53S25 sony projection tv has no sound/no picture
My sony KP53s25 projection tv suddenly went out. There is no sound and no picture. The stand-by light just keeps blinking. Can someone assist me with determining a solution?
Larry, Thanks for responding. My kp53s25 stand-by indicator light is blinking continously once a second, no pausing. The possible problem indicated by this type of blinking could be no reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective. How would I go about determining which one of these problems I have if any and then fixing it. Is it at all possible that the convergence panel would need to be replaced?
That would all depend on how much electronic circuit training you have and if you can use a schematic and know how these TV circuits work. You will need a mutimeter and a scope to trace the video. The problem you have is on the M board or the U board, but a good going over, checking voltage will determi this .

I located 2 blown fuses (black) on my KP53S25 that are positioned right next to each other on one of the boards. maybe from the M or U board, not sure. Does this info help you pinpoint my no sound or picture with continous (no pause) blinking led indicator light?

How many times does this light blink, as there is a built in diagnostics for these Sony TV set.
