Question about Mitsubishi WT-46807 46" Rear Projection Television
I've heard several ideas on what to fix when one of the colors separates from the other two on a rear-projection television:
(a) the convergence ICs are bad (STK392-570), or (b) the caps are bad, or (c) some of the soldering around these previous two categories of items needs re-working.
What ever became of the other folks suffering from this problem with their WT-46807 televisions?
Where can I get a manual to help me remove the circuit tray? I took the back off, but I can't even find the convergence chips.
1)The correct solution is (a)....
2)Concerning pulling the chassis on a 46" Mits...
due to compact size,your set has a higher degree of difficulty.
The 73", 65" and 55" are easier to do the same repair.
3)Begin by removing lower front cabinet,then remove front access
panel.Next provide yourself with plenty of light to see inside....
Remove chassis bolts (3) in rear',unplug as needed,noting location
and routing.Next,locate snap clips on front of circuit tray-Release.
Gently pull back on chassis until clear to remove center board.
Almost must pull all the way.Remove & rebuild center PCB.
