Hi: My acer56c is eight years old and humms while turned on as well as getting the horizontally linear blue occasional flash across screen.The colors when turned on are not 'initially' accurate(Orange vista logo may be light blue). Is it wise connecting this to a brand new DELL ? BMW

The vertical output section circuit has the fault. Contact any experienced service technician. This is not a user repairable fault.

I have seen this problem before. It is usually caused by a malfunctioning color wheel. Replacing it should resolve the problem. Let me know if you wish to fix it yourself so that I can find you a replacement.

Hi,
According to the symptom the FBT Which is called "Fly Back" is popped, and it needs replacement. Details like Part No. and Description is given below:

145334611 FBT ASSY (NX-6000//J1J4)

Replace the FBT and your tv work fine again.

the problem there is a loose connection on the board,you said that you smacked the right side of the tv and it goes normal.there are parts that should be resolder on the board in order to back into normal operation.

is it vertical problem or retrace lines can you tell

change the ram and viedo card agian

sounds like bad capacitors on the FMT board need replacing that is a common fault with the first generation DLPs There are 3 bad capacitors.

Yes, Convergence settings should be tried first before any color adjustment or any fluid changes are done. Remember that there are 3 colors to notice. Red, Green, Blue. The Green is the only one that you can not move with an adjustment The Red and Blue is ligned up on green. Some cases it does matter how linear the Green color is across the board, just how close you get the blue and red on top of green is what matters.

How old is this TV?

Sounds like the flyback transformer is bad. couple of 100 dollars if it is that
