It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hello,

This is most probably a faulty DMD chip, because of the snowy effect, if it only happens for some seconds then it might need replacing. Normally this does not go away, have you had any repairs done to this TV recently?

No picture on a DLP when you can see the lamp is working is ALWAYS the DLP chip. BECAUSE you recently replaced the color wheel, i suspect that the LVDS/data cable to the light engine was not plugged in well and has come loose. I suggest checking and rechecking every cable and plug you can find.

The noise could be one of the cooling fans has some debris in it or the most likely cause is the color wheel is starting to fail and will have to be replaced. If the picture starts to have color or picture problems then it is the color wheel.

We have the same DLP set and had the same problem. The Color Wheel, P/N BP96-00250A, a $200 part needs replacement to eliminate your problem.
