TS 223 Never used..and already dead!

[Goahead]

Hi Keldo

Thank you for ideas and lots of info.

A started with the dimmer module jung 3602 instead of the shorted
module TS223, cause it seemed more chalenging and at present time,and
i cant remove the TS223 from board yet.

Dimmer module is not short circuited but does nothing when program
button clicked..

Inside The Jung 3602 i have 2 PCBs:

- Bus control + Dimmer controler
- Power zone for dimmer (mosfet or triacs!!)

Its a Insta 299 016 07 Module from Insta Company (didnt know that jung
really doesnt do anything!!)

Bus control is made with transformer + FZE1065EG (Infineon) +
68HC705B16N (Motorola)
I found out that one diode was dead...so maybe someone connected the
bus wrong way and kill the chip.

So after removing some components i concluded that i have 7,2Ohms
(like a short) bettwen pins 4 and ground of the FZE....
Theres no voltage output in pins 1,4,8 and 9.. so thats why the rest
of the circuit is dead.

I have tested the microprocessor with 5V in VDD and enabled the reset
and Save pins, and it seems to be ok, since i press the reset button
and the led goes ON.

In conclusion...FZE1065EG and one diode are dead...everything else OK.

Now...opternus sells the chip (if its not obsulete) but it also comes
with transformer...7,5Euros + shipping.
I have some spare modules (other brands) but i dont want to remove the
FZE from them, cause they work ok.
Any other locations for buying in europe would be greatfull.

Thank you all for all the help
Ill keep you all informed when i fix at put the module together (get
the FZE and solder it), and ill keep people informed with progress
with the shorted one TS223.

If you have any dead module that you want to fix..i will be glad to
help.
