Question about Mitsubishi WT-46809 46" Rear Projection Television
If it is a WT-46809 it uses two of the STK-392-570 CONVERGENCE CHIPS.
I have repaired a lot of these sets and they often develop internal bad connections---most of the time resoldering them will not help--both chips have about 18 pins and what I have seen (dozens of times) the pins break loose inside the chips.
Considering the time and trouble just to get at them and the fact you can buy a pair of the chips on Ebay for about 14 dollars plus shipping I just replace them and problem is gone.
I have start to finish, step by step instructions for this repair in this set--tell you everything you will need and how to do the repair.. I am going to post a photo so you can see what the chips look like.
If you want the instructions let me know and I will post them here for you for free.
If this has helped you rate this solution as I do this here for free.
