Hi CasparV,

I'm glad to hear the instructions helped you also to fix your screen. I have fixed mine some time ago and it is still working fine. The capacitor-problem seems to be a very common problem with those type of screens.

Anyway, good luck with your repaired screen.

Best regards,

Volegna

I have successfully fixed my monitor exactly as described above - many thanks for some very good advice.

I replaced the 2 capacitors which were Hermei 1000uF, 16V, 105 degrees. I only had 1200uF, 16V, but they have worked just fine.

Thanks again.

Hi viole Falushe,

I have added a picture that shows the 2 capacitors that were bad from the powersupply. These 2 caps are really C914 and C915 from my powersupply. If you have the exactly same power supply like I have, then you should find them on your board. If it is another powersupplyboard you have, then post us a picture

Anyway here is the picture that shows the 2 capacitors that needs to be replaced :

Be aware : respect the polarity (+ & -) of the caps

Good luck

Please let us know if you have fixed it or not.

Best regards,

Look to the right of the larger part you circled - jump over two aluminum heat sinks - two blue caps.

Hi all, to be short : The screen is already fixed

I couldn't resist to do some solderworks, so i already fixed the 1st of september instead of the 5th .
PatBoots was exactly right , elco's C914 and C915 were lightly bulged. They were 2 elco's from brand "Hermei" of 1000µF/16V/105°C. I replaced them with the same model but from another brand. Now the screen works like a charm . I can turn power on and off with the button and i don't hear anymore 'plops' in my speakers. So problem is solved .

I will test it alot now to be 100% sure but all seems ok. For me this thread may be closed.
Big thanks to PatBoots and jts1957 . I fixed a screen of 325 euros (i'm from Belgium, so here it is in euro's ) that i bought more than 3 years ago with replacement of 2 elco's that costed me only 0,66 euros.

Hope this response helps other people too

Thanks all and best regards,

Hi all,

Helpmeout again
I registered as "volegna" now because then I can add 4 links to pictures I have made from my bad screen. (I accidentally got blacklisted as unregistered user 'Helpmeout' because I wanted to post 6 links to the pictures I have made of my bad screen, sorry for that, didn't know i could only post 1 link as an unregistered user ).

Below, i uploaded some pictures of the boards for your interest. Please be patient because some pictures are large in size.

Here are the links for the pictures:

If you have comments or other helpful info, let me know .

Best greetings to you all.

Hi folks,

I looked at my power supply board to the elco's, none of them are open, but I do indeed see 2 elco's (of 470µF) are lightly bulged. So i will start to replace these 2.

I will let you know what my results are on the 5th of september, if these replacements helped or not. Currently I'm busy with other things now, but on the 5th, I have time to do the soldering of this board.

Already thanks for your answers, keep them coming

Thanks & greetings
