Problem for Sharp 55R-WP4H 55 in. Rear Projection Television

Sharp 55R-WP4H view timer blinking




By rlawrence947 on Jan 16, 2009

" "
I was reading on this sight about this problem one expert said something about you could unplug a b+ connector in the tv and it should power up if the stk392-040 convergency part was bad the only problem is I can't find (inside the tv) a b+ connector maybe I don't know what it looks like.What if I tried to power it without the stk392-040 board plugged in at all.

IF THE B+ SUPPLY IS BEING PULLED DOWN DUE TO A SHORTED IC. UNPLUGGING THE CONVERGENCE BOARD MAY ALLOW THE SET TO COME ON. COMFIRMING YOU HAVE A PROBLEM WITH THE CONVERGENCE IC AND POSSIBLE IC'S.
