Your problem is the convergence IC;s should be replaced. If you never repaired a tv before how are you going to know what the schematic symbols are?? Do you know the HI voltage saftey issues involved when servicing a TV set. Do you know how to unsolder and solder?. Do you know the resistor color codes? Do you know how to use a multimeter and an osilliscope and do you have one. A TV set or a projection set is no where for a handiperson to experiment with!!! It has very high voltage inside them even when they are unplugged. You can also cause more damage to the circuit board if you dont know much about solid state electronics. Please if you insist on this yourself make sure your familey is available to call a doctor for you as this is no joke. I have seen grown men get tossed againstthe wall when working on a TV set. Please get a pro to assist you with this repair as its should run you in the area of 250 to 350 bucks. Good Luck

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

Mitsubishi TV Model #WS65903 - Green Shadow Lines on Screen


Something is not right here--The green is adjustable in the TECH menu--did this person adjust or try to adjust in the customer or the TECH menu?

If you confirm actual model number I can tell you how to get into the TECH menu--yes--green will not adjust in customer menu--it determines geometry and is only adjusted in the TECH menu.

Also, this set requires any convergence adjustments to be done in 480 and then in 1080--if only adjusted in one mode the other will still be bad.

Let me know if you know how to adjust in TECH menu or not--with exact model number I can tell you how to get there.

If this helps you rate this solution as I do this here for free.

Blue and Green line thru center red shadow on both sides


most likely if the line is top to bottom you have no horizontal deflection
this could be caused by a number of things
but if you continue to turn it on it will score a burn mark on the face of the three crts
id call a service ctr in your area or you might try replaceing the deflection bd and see if this will resolve the problem

the problem could be a open yoke return cap but if you dont have the tools or knowledge this woulld be one better left to sme one more experianced with this



please let me know il be happy to try and assist you further

Red & green lines


Sounds like you have hardware failure in the convergence circuit. Some combination of the IC's, fuses, and/or resistors has failed. Repair cost is $250-$400 parts & labor
