Iiyama 2607WS suddenly dead

Re: Iiyama 2607WS suddenly dead

The infinite reading for the MBR10150CT seems a little odd. Sounds like the middle pin is connected to nothing. Check it again. If you get the same result, remove it and check it out of circuit.

Re: Iiyama 2607WS suddenly dead

I just ordered two 20100 and two 2045.
Will solder out 2045 today and check it.
The Caps are Taicon 25V 470uF. Seem to be ok.

On center pin of 10150 I read +12V. Pin is connected to ZD770/1.

Re: Iiyama 2607WS suddenly dead

After another resistance measurement of 2045, I think it is intact.
I will solder the new 20100 in and check again.

Re: Iiyama 2607WS suddenly dead

Ok guys, I soldered the caps back in, put silver grease on the new MBR20100CT, soldered it in, plugged the PS into the wall and measured perfect ~5V and ~12V on the connector to the controller board.
The screen is working like a charm for hours now. I am so happy. Thank you very very much for your help and patience budm and jetadm123. Cost me a buck.

Merry christmas to you and the Badcaps Forums!!!

Thank you for posting the repair feedback.

Re: Iiyama 2607WS suddenly dead

Excellent work! Since you were able to get the replacement part so quickly, can you share your source, since so many people in europe seem to have trouble locating parts.

Re: Iiyama 2607WS suddenly dead

The parts are from ju-tec.de. A few kilometres away from me.

Thanks to this thread i fixed my Iiyama Prolite E2607WS.
Exactly the same part was broken.
Thanks to all

Thanks a million to jetadm123, budm and others who helped solve formatthias problem. I had a 2607WS with exactly the same problem. I was on the verge of trashing it. I replaced the MBR20100CT and it is now WORKING!!!!!
Brilliant!!!

Re: Iiyama 2607WS suddenly dead

I think I have the same problem. I have removed the MBR20100CT from the board. On a digital multi meter I test 0.245 volts on each terminal and nothing when reversed. This sounds like it is ok to me but the only experience I have is this thread and some youtube videos about diodes? Could someone please advise if this is ok or not thanks.

What is the exact problem do you have, blowing fuse?
How about some good clear pictures of YOUR boards?

Problem is the same as the op plus the guy above. Just stopped working completely, no power light nothing. I have two of these monitors so have tried different lease etc. As in both cases above it was fixed by swapping out the MBR20100CT but since I removed it I get the same readings between pins 1 and 2 and 2 and 3 so I guess in my case this is not the problem.

Re: Iiyama 2607WS suddenly dead

What DCV do you have between the two legs of the main filter cap (if you read the thread, there are step that we went through to find out what is going on).
All the fuses tested good with <1 Ohm?

On the main cap I got 315 volts. The 2 fuses show continuity and no resistance.
