Ultrasonic cleaner is not working. - GSM-Forum

Hello guys.I have the ultrasonic cleaner "DAYU" - one mode with one button.When I switch on the cleaner,the red led is shining,but piezoelement is not vibrating - but it is operable - i'm checked the piezoelement to connecting by another Ultrasonic cleaner(Baku 9050)
There attaches of destroyed cleaner,anybody help me to find the scheme for...?

Why need schema? Dezassambly and check components..sure diods or/and tranzitors brocken! But if you don`t have skils for this job..

I'have a skills.I know this is their often reason - I marked it on the attach by red arrows.(look at tha attach,please)...There are?

But why these transistors have often damaging in a lot of ultrasonic cleaners?
So must to be install more powerful denomination transistors?Are transistors universal in a lot of cleaners?I want that ultrasonic cleaner are working more longer.

When cleaner was working - the transistors were very hot!
Please give your advices,guys!

Bcz is a cheap ultrasonic cleaner,bcz is chinese job..bcz a lot of reason! Find datasheet of that transitors and find other more powerfull! I know is verry hot..maybe change aluminium radiators..put other more big!

Djdansmart thanks,the problem is resolved.I'm changed 3 resistors and these(as shown on the picture) 2 transistors.And cleaner be operable.

What is number of these transistors ? my transistor replased by wrong value.

please tell me current number of transistors.

Maybe one is for you:

protons · 11-05-2010, 07:10

Transistors is ST13005

djdansmart · 11-05-2010, 08:20

Or BUT11..metalic case!
