How do I replace the stk 393 110 chip

If the model here is correct it is either on one side of chassis or on middle board---I can tell you what is involved but need to know if on left as seen from rear or in the middle board the set has.

You might also tell me what is wrong--just blue skewed?

In either case chip has to be got at--side mounted and not in middle is harder.

let me know where its at (this is a old set and only a few of the chips in those ever fail.

Picture is no longer working properly. Picture is blurry and colors are all wrong. Ghost image. Happened all at once not gradually. What needs fixed mitsubishi 65" medallion series. appox 7 yrs old

Your Convergence ICs have failed. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.

Note if one STK chip fails, you replace both regardless.

Medallion VS-60719 with convergence problems, blue shadows, unable to correct by adjustment.Very handy and will to attempt repair. Could someone direct me in the right direction

If you mean smearing when you say shadow then your problem may not be the convergence. The blue tube may be faulty(weak), try to play with the contrast and brightness levels and if that smear varies with the adjustment then your problem is most likely the tube, in some case there might be a problem with the screen supply(voltage) or the drive circuit. good luck

Mitsubishi medallion VS-60719 with convergence problems, blue shadows, unable to correct by adjustment.Very handy and will to attempt repair. Could someone direct me in the right direction?

Yes, this model uses a single STK-393-110---IT IS A 2001 MODEL.

If I remember it correctly the IC will be on a huge metal heat sink on the far left side of the set (as you look from the back) there is also a small IC on the same heat sink.

Not the most easy set to do this repair on and if you have a problem with the blue--it may not be the chip.

I have seen 3 or 4 of these where the problem was broken connections on a 10 or 12 pin plug at the left front of the board----

The way someone would pursue this is get the entire chassis up so the bottom of all the boards faces the back of the set--The plug goes to the convergence yokes this set uses---I have seen several where several of the pins had broken loose from the circuit board--normal with expansion etc.

If I was repairing it I would look at the plugs in that front left area FIRST! The last one I fixed had bad connections on TWO plugs---with the board up they will be clearly cracked or ringed--broken loose--if the set for some time would be good and then go bad it is most likely a solder problem.

Resoldering is much easier than replacing that chip!
if it is not resoldering the Chip can be purchased on Ebay for about 14 dollars plus shipping.

If you have someone come out tell them what you know---The plugs (as you look from the back) are up front and towards the left side

If this information has helped you rate this solution as I do this here for FREE.
