Re: Herringbone pattern

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.

Picture is very red and slightly distorted

A very red picture is usually related to the Red CRT or red CRT drive board being defective. The convergence will only mess the alignment up and cause the picture to appear 3D it wont make the Picture take on alot of red tint.

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.
