SOURCE: MITSUBISHI WT-46809 46" HDTV CONVERGENCE IC PROBLEM

On this set if it still turns on and you see a picture then the only thing you will need to replace are the ICs. Use heat sink compound on the new ICs before replacing the old ones. If you have a parts supplier in your town, then, use them. If not, Radio Shack will do in a pinch. The old ones may be stuck to the heat sink, so, a flat blade screwdriver may help with that. Use a clean soldering iron and good solder wick. Good Luck

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

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.
Bill

U check all the resistors with the Ohm Meter?All the resistors u check it in tolerance?Resolders all the resistors,so it make good resistance for the ICS?U do all these steps,u still have problems,Ur ICS some how it shorted it dead,again.

SOURCE: I have a Mitsubishi wt 46809 with a error code of

That is error code 22 which means the unit had a momentary recovery from a reset. You should unplug it for 30 minutes, then plug in and try it again. This will reset the fault and if there are no other problems the unit will work ok. Let me know if you need more help. Thanks for using FixYa and for the generous rating.

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.

Mitsubishi wt-46809


the vertical deflection IC if defective will cause the protection circut not to let the tv power up ,it has a thermal protection circut as well
here is the vertical deflection IC # la78045
and here is a link for the NTE equivalent part and specifications and pin layout
http://www.nteinc.com/specs/7200to7299/pdf/nte7209.pdf WARNING if you heat up any component to long or with to hot of an iron you can dammage the component and or the thermal protection circut
but I believe you will also have to replace the flyback (high voltage transformer ) with wire giving to much voltage

The board for this 2001 Model is no longer available. Now, if you can solder, you can repair yourself. The parts you will need are two STK 392-570 (HIC), convergence IC's, part number 270P150010.

If you can't replace yourself, please call an authorized service center to give an estimate....

Good Luck, big IRISH.

Mitsubishi WT-46809 Intermittent color problem


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
