Hello,

since you had been observed the green in the bottom, it means that voltage drops in its components is not correct. please check the Vertical and Horizontal regulator and then the capacitor that digest right voltages to project in the projection screen.

I suggest you make sure the bulb/lamp is properly installed and working correctly. It may need replacing.

it seems like the plasma display driver circuits are going bad.

Did you replace the entire convergence board?
With the information you are giving us, we can suggest to check the voltages from the power supply going to the convergence board. Double check the connectors that connect to the convergence board as well.

I have a panasonic PT-47wxc43 projection tv. I have green and purple halos coming up from the bottom. The screen has purple and green double images which are worse from the bottom up.


Hi,
This problem is due to convergence output ICs failure and both chips will be replaced to fix the issue.
There are two big black ICs installed with aluminum heat sink on deflection board, these are convergence output ICs and will be replaced to correct the problem, it is common problem of rear projection tv.
Below image of deflection shows ICs (marked in red) that are need to be replaced.
IC number is STK392-110 and available with Part Store for $32 each.
Click above link to see an image of IC.
If you are handy with electronics stuff repair and can replace parts in tv circuit board then can replace these parts yourself or ask local tech to help you.
Hope these info will help you.
Let me know if you have additional question.
Thanks.
