|03-06-2008||I'm really not happy with the way the blue is showing on the screen at the moment.
I have a couple more STK392-040's here. Could it improve it if I change the blue one over perhaps?|
|03-06-2008||In both cases, the fault is most likely a short somewhere on the secondary side of the power supply.
Check all output voltages for shorts. In the tv, a common cause for this kind of problem is a shorted line output transistor, possible as a consequence o|

Also, check the drive to the CRT cathodes by a scope. If the drive signals are normal (both p-p value and dc level, no black clipping etc), then the CRT is probably faulty. Of course, you could try t|

|03-06-2008||Answer to that is Nope.
Changed the IC over and is still the same. Blue is blurry and doesnt seemed to be repairable with the Focus/Saturation/Lens dials. :(
It probably is, but it eliminates the Perfect focus, and is still very slightly off (notic|
|03-06-2008||Re:problem with Sanyo DP32746||I checked out the set again today. If I shine a bright flashlight into the screen at an angle, I can see pixels and movement, so I think the panel is ok, however, I suspect there may be a problem in the inverter board as I checked F100 on the inverter boa|

I have a Phillips 50in Projection TV:
The picture is very blurry and you can't make anything out.
If I adjust the color for the green and red tubes the image clears up ,but the blue tube stays blurry.
|03-06-2008||Swap focus/screen leads on the block to see if it's the block. Swap green and blue. Who changed the fluid? When I do these I do both the green and blue. Red doesn't grow the algee. It looks like contaminated fluid to me. It's not convergence.|
I bought the TV from someone and they said the fluid was changed.
I took out some fluid out of the blue tube and it's crystal clear.
How exactly does contaminated fluid look like?
I will try swapping the screen/focus leads on the block.
