Title: Huston, my TV has a problem!
Post by: Dusty on June 20, 2007,06:54:19
Morning chaps and lasses...

I need some advise please. I have a 28" WS JMB 66W and to be honest it has served me very well, coming up-to the 5th year of trouble free viewing (who said JMB were crap) however an audio fault has started to creep in. Long story short, audio appears to fade in and out one minute its fine the next minute is faded out? 8 times out of 10 a simple switch off and on will restore the audio, this will last for anything up to an hour OR a few minutes OR if I'm unlucky a few seconds... Its driving me potty!!!!!!!!

NOW the funny bit, my local TV repair shop will fix the problem BUT I got the usual spill goes something like this "OH its a JMB, well sir the parts for these TV's are hard to obtain and rather expensive and its a pig of a job to repair any audio related problems with this brand... he goes on to say its gonna cost me £60 OR I could buy a refurb Sharp which looks identical to my JMB for £75??!!??

So my question if anyone knows, what is the base cost for the component needed and maybe a difficulty rating between 1-10, 10 being bloody difficult. I have basic electronics knowledge and know what NOT to touch in a tv..... I value my life :-)

Can anyone help?

Thanks Dusty

Hello Dusty this model is if I'm correct a vestel 11ak19pro chassis which is pretty common to your average repair tech so parts should be freely available and pretty cheap too.As for your problem well it could be down to a number of things which without proper testing with scope etc is pretty difficult to determine,however I would say that I have encountered various audio faults with these models that are very often attributed to the audio output ic.Can you determine whether it is affecting both speakers?

Hey kgreeny, thanks for the reply. The audio dropout affects both speakers all that remains is a low volume hiss if that makes any sense?
