    He did not say what part it was, just that it would have to be taken in to be worked on. The pattern is there all the time on all channels and he hooked the tv up to different inputs and it was always there. He said he was hoping it was the tuner, but it wasn't.

    I have the same problem, except mine clearsup after it is on for a few minutes.

    Did he say what the fault/part was that he needed to replace?



    Is the pattern there all the time, regardless of input selected eg: TV, DVD etc? Does it appear on all TV channels?

Herringbone (and other patterns) can be caused my many faults, the obvious one the tech was looking for was a tuner/interference fault.

Another common cause is a faulty power supply.

Difficult to say without having the TV on the bench.

I'm a bit suspect about the $400 - $500 repair cost though.

Perhaps try another tech?

I doubt it's a DIY repair though.

Let's know how you get on.

Herringbone pattern at turn on clears as it warms up.


Does your TV show red, green and blue colors separated?

If the answer is yes, the problem is in the convergence circuit.

There are 2 integrated circuits (STK392-XXX) that need to be replaced by a qualified TV technician. The repair will cost around $150 or more.

How to change the brightes


A fairly old model is listed here(KP-61v85) this answer is based on that model number:

If the set has not been serviced for a long time with set unplugged remove rear cover and locate (hard to miss) the three large black lens at top of chassis--clean the lens with a lens cloth or a paper towel with glass cleaner sprayed on the towel.

If the lens are dusty/dirty they will diminish the brightness and clarity of the the picture---they are the light source for the picture in this set.

Do you have another electrical device too close to your tv?
those patterns are caused by AC power leakage. You can move other devices i.e.sat box etc. further away from your tv to fix this.

What causes a herringbone pattern on L172Wt television and composite input, but not PC input?


Your PC input is a secondary interfase, it does not go thru the IF and tuning sections.
It is possiable the if section has taken a surge and will need to be serviced.

Bad picture quality


You do not need to change the CRT's or lenses. The failure on this TV is the convergence ICs that became defective.
If you know how to solder, this should be an easy fix for you.
The IC markings are STK392-150 with locations IC1502, IC1506, mounted on a big heatsink(s).
If you want to change the complete assembly, you can check this link and ask them if they have the assembly where the STK392-150 ICs are mounted.
Good Luck.
