please help me for identy caps ps4 pro firmware 8.03
Good morning,
Could you if you know them give me the values if you know them of the capacitors that I surrounded it is to save a ps4 pro in firmware 8.03.
They are right next to the 12v and 5v connectors
Thank you and I hope you will be of great help to me.... -

Good evening
The problem came from the YSUS card.
everything is back to normal.Leave a comment:

Re: artefacts Lg60PZ550
I found on ebay a YDRVBT card, at startup the lowest to burned buffer.
So for me Ysus HS card, I still have to find one.Leave a comment:

Re: artefacts Lg60PZ550
Can I safely change the buffer cards?
Knowing that I do not know the voltages delivered by the Ysus card to connectors P201 toP205.
Thank youLeave a comment:

Re: artefacts Lg60PZ550
I dismantled the upper Buffer card and then started the Tv.
Apart from the truncated image I have much less defect of pink dots on the USB source see almost absent.
ref EBR718449201
If I remove the lower buffer I only have lines with a pink dominant on the upper part.
How can I test the buffer?
thank youLast edited by pasdebip; 06-27-2018, 02:31 AM.Leave a comment:

Hello
Already done, more reflow of welds .
No effect...Leave a comment:

Re: SAMSUNG UE55D6507 - vertical bars / lines
Hello
I had the same problem on a samsung UE48C6700.
I solved it by pressing one of the motherboard chipset with an inner tube wedged between the chipset and the TV cover.
Try on all the bga on the motherboard, mine works very well for 2 years now .
In my house it worked.Leave a comment:

Re: artefacts Lg60PZ550
Unfortunately the welds of the coils are good but I all redone.
Without improvements
Can you tell me where the buffer is on the Ysus map?
Thank you...Leave a comment:

Re: artefacts Lg60PZ550
Hello
Here's the latest news,
I checked the voltages at startup except VZB which rises to peak at 127v and then goes down to 107v I found nothing abnormal.
Friday I had a tech from lg who was thinking about an old tile or a filtering problem on the ysus card.
Here is a copy of his email
"Hello,
Top and Bot are the cards to the left of the Ysus.
With use, if poor filtering is performed, the Ysus may be "tired".
It may be another card, but it's no longer available."...Leave a comment:

Re: artefacts Lg60PZ550
Good evening
I just dismantled the six cards, I didn't find a bad solder.
Then TV on the USB source to see if my actions changed anything I tapped all the connections as well as the components .
Nothing change...
I still have to control the starting voltages.
Is it worth checking all capacitors by removing them (voltages ok)?
Can the motherboard be the cause?
Thank youLeave a comment:

Re: artefacts Lg60PZ550
Hello Thierry,
Thank you for your help
I used a camera already controlled the hot spots without finding anything abnormal but I will start again (it is long....)
Between now and Friday because I am at work I will also look in more detail at the connections and layers of the six maps.
I'll try to control the voltages Vx at startup.
What I can already say is that on the Zsus card a runway is taken off at the foot of a capacitor, without breaking the continuity in the air to be good( ohmeter).
I glued...Last edited by pasdebip; 06-18-2018, 11:46 PM.Leave a comment:

Re: artefacts Lg60PZ550
Tonight I'll take a video of the start of the TV, this one looks a lot for a split second like what you showed on your video.
I ran the Y and Zsus cards through the camera without finding anything obvious.
I didn't specify it but if I don't use the APS image mode on the tuner the pink dots reappear but much less than on the other sources.
Thanks ThierryLeave a comment:

Re: artefacts Lg60PZ550
the defect of pink points is increased on all the sources except the tunerLeave a comment:

Normally this picture is better.

Va and Vs voltages were taken from this connector.
The defect on the video indeed resembles what I had initially before modifying Vy
Here's what I have now:
almost only with usb port

Re: artefacts Lg60PZ550
Hello
The fuse on the Zsus card is ok.
The card reference is EAX62076601
Cordially
