20 Most Recent KEF Audio KHT 2005.2 System Questions & Answers

My Dad had the same problem. KEF admitted it was a paint problem and replaced the speakers.

Unscrew the front of the speaker, hold the casing over a baking tray, repeatedly wash and work the thinners into the casing with a clean paint brush.This will gradually remove the sticky coating leaving the surface smooth and clean. Don't forget to wear rubber gloves.

The KEF-Subwoofer range (from the PSW1000 up to PSW 3000?) have some built-in flaws in the electronic design.

I just fixed my PSW2000 working along the repairing instructions from:

Works! Costs have been about 35,- Euro for spare parts and some (too many) hours of work. If you are used to electronics and soldering you may make it in 2 hours.

You have a bad set of Audio output IC's for the sub. There is two of them. TDA7293 REPLACE BOTH!!!
There is 4 on one side of board,and 2 on other "also 1 small one" The the two are for the sub,the other 4 are for the main speakers/surround. They sell on Ebay for $6-10 each or a kit of all 6 for $25.

chik power sours first
thaen chik transformer inside
u will see it burned if so chang it

check for the connection og the main wire is cut.. or check the supply..

if u are a technician then its easy to check, problems are, blown fuse, power amp IC output transistor may be blown, check for burnt componenets. changing and blowing a fuse means ur output IC or transistors are shorted.

Either you need new high quality cables,or your amp has output filter capacitor problems.
