Question about Mitsubishi WT-46809 46" Rear Projection Television

1 Answer

Installing STK392-570 IC's on a Mitsubishi WT-46809

I have a convergence problem on my WT-46809. A previous post informed me that the stk392-570 IC's should be installed on the center circuit board on large heat sinks to remedy this problem. I have inspected the tv to find none of the IC's are labeled STK392-570. How do I figure out which IC's to replace? How many should i order? Your help is greatly appreciated.

    I have the same problem on my tv. The convergence problem is awful. I'm able to adjust the lines right and left but I can't adjust the lines up and down. Anybody have step by step instructions on replacing the ICs. I'd love to salvage this great tv.

    I had the same problem with my MITS 46809 TV but all that was necessary was to resolder these ICs. I suppose the heat sink is inadequate and over time the heat degrades the solder. I ordered a service manual, took the circuit board out and resoldered these ICs. I made sure the heat sink had enough thermal compound between it and the ICs. It has been working well now for a couple of years.

Tburg05,
Whoever told you that the WT46809 took two STK392-570 Ic for convergence amps were absolutely - 100% correct... The amps are located at position number Ic8c01 & Ic8c02 on the board. Very difficult to miss too they are about half the size of a pack of cigarettes and 1/4 as thick. They are Mitsubishi part number 267p150010 and after replacing them you want to also check all the low ohm resistors in that circuit for the yoke return.
If you order them don't get them from ebay or some other less than ignorant place, our industry is loaded with chineese knock-offs that would last tem minutes in your set before failing again... Personally I'd order them from Acme Enterprises out of Florida, 800-575-9833 and know that they were Sanyo originals that way.
BTW: If you replace these yourself make sure to use a generous portion of heat sink compound on the new installs for heat dissipation.

The 2 fuses you mentioned are associated with the convergence IC. If they are open then the convergence IC is either bad or you have a "cold" solder joint on the IC.

I have the MITSUBISHI WT-46809 46" HDTV CONVERGENCE IC PROBLEM as well. I just ordered the STK392-570 IC for 7 bucks and I am going to attempt to switch them both out (two of them). I am getting the overstated "bow tie", "RBG separation" issue that you are talking about. I am going to attempt to de-solder the intergrated chips and put new ones in. I figure it is worth the shot, insted of paying 350-650 bucks to have some **** with average skills do the same I figure it is better to have this **** with average skills do it and keep the cash. I will let you know how it goes.... DJ
