PANASONIC PT-51HX41E I HAVE A BIG BLUE SHADOW,I TRIED TO FIX IT WITH THE CONVERGENCE,BUT IT DID'T WORK.CAN I FIX THIS PROBLEM MYSELF OR I HAVE TO SEND IT TO GET REPAIR? THANKS FOR YOUR TIME. PANASONIC 51HX41E

have you tried to run auto convergence

Repairman needed. If it was like this when he "fixed" the convergence issue, the job was obviously not completed.

My first guess would be a bad convergence amplifier - this is common, although usually all three of the amplifiers in the integrated circuit die at the same time, which throws off at least two colors and creates a "bow-tie" effect. I surmise you have half of a bow-tie in blue only.

If you could look at the blue output waveforms with an oscilloscope, you would see right away if this is the problem (flat-line instead of sawtooth wave). It is possible that both of the blue convergence amplifiers are working, but one output is not getting to the blue deflection yoke.

Don't mess with the convergence anymore until you get this taken care of. Changing the convergence now will only make it harder to get it back to where it should be once the circuit is fixed.

This is a convergence problem that can be as simple as poor solder connections at the convergence ICs to dfective ICs. Expect a parts cost in the $25-$50 range for this repair. If you feel confortable working inside the set and can solder, update this and I'll supply additional details and instructions.

This is a convergence output IC problem. convergence board (main Board) would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

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

trust ME when i say setting convergence after doing repair takes alot of time to do /you can damage set if you do not have service codes and values/ you also must have the hand unit that comes with set in order to even get into convergence circuit, call your repair shops ask if they have a good blue tube for set and how much would it cost to repair?ARE you sure blue tube has been removed from set.?
