Hello again


This 90% of the time for 6 and 7 blink error codes on this model is usually failure on the D board of IC6501 and IC8002 both are MCZ3001D available here


An ability to solder and de-solder is required as is to own a quality soldering iron as the print is double sided the chips are difficult to get out, however use of good desolder braid will make it a lot easier, all available from Radio Shack or equivalent


The D board makes up part of the powersupply and deflection and is mounted just to the left with the bulky horizontal output transformer on


Alternatively you could take the board out and despatch to a company called ringing them first for advice on charges


A technician would charge $200-$300 for this repair depending on where you are


If you have questions or need more advice please let me know
