Question about Mitsubishi WS-65809 65" Rear Projection Television

1 Answer

I have a mitsubishi ws-65809. I relpaced the STK392-570 ICs and turned on the tv and it powered on for 2 secs and went off. I ran the test and got a 2 and 2 blink. Then ran test and got a 1 and 2 blin

I also chipped some of the covering off of circuit c8c04 that is right behind the right IC. Will this cause a problem for it powering on?

If you unplugged the set you will get the 1,2 no error found, the 2,2 is short protection, I hope you had that before the chips were replaced, it is one or both of the pico fuses bad that protect those chips.

see photo of board, locations are 9FAo4 and o5 on the middle board where the chips are but further back.

The most common failure are the two convergence integrated circuits part # 267P173010. The two pico fuses may be open as well, which come from the power supply and provide +24 volts and -24 volts.

SOURCE: My Mitsubishi ws-65809 will not power on and gives error code 22

Your symptom sounds like at least one damaged convergence IC.

On Mitsubishi's you can sometimes rework the solder connections on each of these IC’s, although, if the convergence does not fix itself from time to time, you most likely do not have a bad solder connection. You will have a faulty IC. Since you now have an error code of 22 (which indicates a short on one of the power supply lines) I recommend replacing them both at the same time because the chips legs can fall off due to the heat of the IC. If you have a good low wattage soldering iron ~ 45W (available at radio shack) you can perform the repair yourself, and this will most likely take care of the entire issue.


I like to remove the board that the IC’s are on so that I can unsolder the connections and clean then up using solder wick (this is also available from radio shack). Removing the board is not a real issue as the connectors are all labeled with an alpha number, so that you can connect them back real easy. There are three in the middle towards the front that I like to mark with a sharpie as they are the red green and blue convergence coil connections (they are all the same size in a row). Just mark them with slashes, like I, II, III, or something like that. If you mix them up it is not a big issue, you can test swapping them around until the picture lines up.

Please be sure to remove the entire white heat sink compound on the heat sink and apply an even coating over the back of the new IC’s. You should also bolt them down before you solder them in so that you have them at the correct height.

There are two very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. I think that the IC numbers will be IC8001, 80002.


The IC’s are large and black, you cannot miss them. They will usually have an STKXXX-XXX number on them.

This repair from a good technician will normally run from $250.00 - $300.00, and sometimes more depending on your area.

There are several schools of thought on the replacement of parts and I firmly believe that you get what you pay for, so don’t buy the cheapest IC’s that you can find. One company I worked for tried this and it only caused more work for the technicians, as we had to replace them with the more expensive ones in the end. I would think that you should be able to find these for around $60.00 each. If you can find the exact Hitachi part, or Sanyo, even though the numbers on the front are the same, and they look exactly like the $10.00 ones, they are better and more reliable.

I usually order my parts from Andrews Electronics in
California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

2-2 is a error code that means short protection.

Usually in this set it means one of the fuses that protects the convergence circuit is shorted because of a bad convergence Ic.

I HAVE PHOTOS OF THE FUSES-- and THE PROTECTION RESISTORS- and I also have step by step from start to finish instructions for this repair in this set.


If you want the instructions and photos give me a vote here and I will be happy to email them to you and answer any questions you have. I have done hundreds of Mitsubishi sets with this problem---I just got home from doing one a few miles away from where I live.

REGARDS, SD TECH

It needs to be repaired by having the convergence ICs replaced or resoldered (if intermittent).

Parts are STK 392-570. Be sure to use thermal paste on the ICs.

Ws65909 powers off about 3 sec after power on


a code will always read 12-normal if you just plugged the tv in. it has to try to turn on then shut itself down to log a code. Or shutdown is caused by something the tv cannot detect . Or a front panel button has failed- does the green light turn on for a second when you hit the power button on the remote? if not try unplugging the front keypad behind the speaker cover.

If your TV is not powering on you probably blew the power supply. These TV are sensitive to power surges. Be sure to use a power strip with power filtering technology (different from a surge protector) costing around $80.00

Convergence ics


www.matelectronics.com Check resisters (low ohmage) in front of IC's, usually discolor or change value.
