Re: samsung ht z310 - FAN_CHK error
I think this fan circuit has to be one of the most complicated I have seen, a temperature sensor control circuit would have been so much easier but instead it is based off volume level. As a result...

Re: Sony OLED TV 4 red blinking lights
I suspect you will find that the thin lines are causing something to overheat which means the T-con will shut down.
I guess you could see what is overheating (a thermal camera helps, but if not,...

Re: Service manuals - going down
Bump so more can see this.
I think Topcat offered a while ago but I'm not sure on what the status of that is. I'll have to ask again.

Hi all
As you all know I am not as active on Badcaps.net forum as I would otherwise like to be, for a variety of reasons, but mostly related to workload.

Re: PN43D490A1DXZA power supply broke?
Unlikely to be power board if Vs is present, even if dropping. Control board will shut down power board if there is a fault.
To test properly you would need to disconnect control board and main...

Re: "Solid State" media failures
Yes, that would be how it works.
You having 100 TB would certainly make that harder! I have at most 8 TB of data, about 2 TB of which is backed up (the rest is easily recoverable stuff, or junk...

Re: "Solid State" media failures
Well, I have 80Mbit downstream, but I don't even have to use that.
The company will send you a 4TB HDD for ~$200 but if you send that back to them, the service is free of charge - you effectively...

Re: "Solid State" media failures
So my solution was to back it all up using my 20Mbit (upstream) connection which took a while! About two months all in with it running in the background. But it did work.

Re: "Solid State" media failures
No... some areas will wear out sooner, but the failures will be random in nature. So it is reasonably likely that several sectors will fail in a small span of time if the drive is used in a typical...

Re: "Solid State" media failures
In my experience, it's typically catastrophic because the failures begin at similar times across the drive.
Once a sector fails on an SSD, the drive will spend a long time attempting to recover...
