My tv will work fine for say 1 minute then keeps flashing green and shuts off i have looked up the code it says its the D borad thats gone bad is there a wasy i can self fix it.
The "D board" is the flyback transformer, but if it was bad, you would have no picture at all. Here is a proven method to get it to work (for a while....)
The adjustment method is to put the set on a video input with nothing conected
to that input. Turn the screen control up slowly until those fine lines appear
and then down until they just disappear. Do this with all three colors. You
might need to turn one of them down a little initially if the set won't stay on
long enough to get to adjustments. You cannot do the adjustment on a TV station
or on live video input. If the adjustments are too high, the set will turn
bright and shutdown. If they are too low you will never get a picture at
You would want to touchup the adjustments after a warmup of a few
hours, then recheck the next day when cold.
If the adjustments are
successfull and the set stays on but the color reproduction is very poor then
one of the tubes is probably bad.
If you are lucky and everything turns
out OK, you will probably need to do it every year or so.
