    Where my I purchase another D board?

  • WSLuck Mar 17, 2008

    I have already downloaded a service manual off the internet. In the troubleshooting section it recommends things to try or look at for all other codes except the code I have. It just doesn't point me in any direction.

    Ok guys, I found on another forum for Sony TV problems a service bulletin pertaining to kv 3xxbr4xx series "D" boards. Although not the same models the same components. Service Bulletin: E28041743 D board failures, recommends changing 2 ICs: IC6501 and IC8002. Both ICs are Sony part no. 8-759-701-01 and printed on their top MCZ3001D. Iam going to install IC sockets for these ICs so I can replace them easier in case of another failure. This has been a very difficult problem to troubleshoot because with the back cover removed the set works fine, and installed the problem is intermittent. I thought this would be the best place to start, I will let you know the outcome.

I have the KV-34-34HS420 with seven blinking led no power problem so I replaced both IC's and I used sockets because of the probable failure rate. I turned it on and it's been working perfect.We bought a new samsung because we thought we needed a new set.Oh well I guess the den will get a nice Sony TV now.I also think the big tube sony has a better picture.

Well..the 'D' Board would show up on a parts list, authorized by the maker. You are encouraged to procure a proper service manual, which will go a long way to clear up any mysteries on this issue.

My washer keeps shutting off and f1 shows up on the panel. i dont have a manual. If this is a filter how do i clean it.


The F1 error code on this washer indicates a Primary Control Board failure.



It is likely that the machine control board will need to be replaced to correct this problem.



The part number for the machine control board is undetermineable because you have not provided me with the exact model # of your washer.



The procedure for replacing the machine control board is provided HERE

LINK: http://media.fotki.com/1_p,wfgstgtftbtkrrdxgtqsskgwtqkq,vi/gfsfgfsgqxgfqtqtgwf/1/1303472/5961857/image55806img-or.gif



NOTE: Be sure to unplug the washer to disconnect electrical power before accessing internal components.



There is a slight possibility that a problem with the pressure switch hose could be causing this problem.

A pinched or twisted air hose can cause this fault code.

When you open the console, check the air hose connected to the pressure switch on the machine control board.

If it is pinched or crimped, I recommend rerouting the hose to resolve this problem.

This may fix your problem without replacing the control board.



NOTE: You may want to check for this condition before ordering the control board. Most electronic control boards cannot be returned for a refund or credit.



If you find no apparent problems with the air hose on the pressure switch, then replacing the machine control board on this washer should correct your problem. There is a risk involved in replacing this part yourself.

As noted above, you could have a problem with the air pressure hose that is not apparent upon your initial inspection. A service technician would normally need to properly and thoroughly diagnose this problem before replacing the control board.
