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

I had the same problem where all of a sudden it started bowing on top and bottom and the colors were bad. I read on here and other sites about the 2 convergance chips so I figured why not try as the tv was going to get thrown away because I could not find anyone that would touch it. Well I ordered 2 stk392-120's (I know others are saying use the 150's or 180's but I just wanted to put the same ones that were in there) I ordered them from electronix.com for 9.99 each plus 6.60 for shipping they took 3 days to get here and I installed them tonight and it worked great. The whole thing took only about 2 hours from start to finish. Here's a couple of tips....the chips are on the far left when looking at the tv from the back, make sure you mark with a marker where the wires go that you have to unplug as there are about 10 of them, each chip has 19 pins that you will have to soder make sure you have a soder ****** to get all the old soder up as you are heating them up, after you are done puting it back together leave the back cover off and turn it on, then go into your menu and go to pictureand go to manual converge and go to undo multpoint and restore factory as this will reset it all. Then if your color is still a little off as mine was there are 6 knobs in the back of the tv by the chips you were working on, find a channel with a lot of colors and try adjusting the top 3 a little at a time till you get the right color that you like. This should do it. It took 26 bucks and 2 hours for me to fix a tv I was ready to replace, thank god for the internet to be able to look stuff like this up. Good luck!

YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.
