I recently got a hitachi 43uwx10b that was was out of convergence. i tried adjusting it and all adjusted well until i tried to adjust the blue. it will not adjust, vertically nor horizontally, i pulled it apart and can see that some resistors looked are discolored and one of the chips had cracked solder joints. i am going to order the repair kit and repair it myself, yet before i do i want to make sure that this could be the problem since the blue wont adjust either way. also their is now a line in the middle of the screen coming from the green lamp. if all other lamps are adjusted down to no output the line can be seen. if the red and blue are on and the green is off the line disappears, turn the green on and it comes back, its just a dark line. this just occured since ive had the tv on for a short time, i blew the inside of the tv out with a can of air, it was very dirty, im wondering did i just blow something ontop of the lamp and that is waht im seeing, does it just need to be cleaned or is the lamp damaged somehow? your input and response is greatly appreciated. Thank you very much.
