This might be something really simple... In a large number of DPTV310 chassis, of which this TV is, the yoke connections where put in place with black electrical tape just below the retaining rings. Job is to loosen the rings, remove the tape and push the yoke back in place and tighten down retainer.. Be careful not to throw off the tilt of the yoke. The adhesive on the tape, over time, gets hot so many time it becomes slippery and allows the yoke to fall away from it's position dulling the look of the image (or focal length) causing the problem you're describing here... It also throws off the convergence - so in attempting to converge it just looks worse. Good Luck Bill

The light engine may be dirty with dust, the polarizer filter burned, or the LCD elements burned.
As a last-ditch effort, the light engine can be taken apart and carefully cleaned using compressed air.

This can be repaired by a Degaussing coil from most TV repair places. If you haven't already you should shut down the TV and wait till it cools maybe 1 hour or so and then when you turn it on there should be a degaussing circut that might clear this up for you build into the set. Its not that strong a signal and usually takes care of minor discolorations. If it doesn't have that then a shop can come and take care of it pretty fast usually.

yes you can get the PT47WX49 convergence repair kit at the following link listed under their Panasonic kits category. The kits contain the two Convergence ICs and the feed resistors plus a CD which has the installation instructions. www.tvrepairkits.net
