Re: Philips 60PFL8708S/12 - QFU1.2E LA - Error code 53

Today i've downloaded RT809H & F new software, there's a specific procedure to program those NANDs, i followed a YT video but it's in Spanish, maybe have to press first "Verify bad block", then "Settings", then "Skip BB and realign data" or "Skip BB and rebulit BBT", then write the NAND, right?

This was explained to me by an ebay chip seller..

I'm speaking from first hand experience. Perhaps they were trying to justify their price or put you off from buying your own programmer.

Copying nand chips it's a complicate job since every chip borns with various bad blocks, different from each other, so before writing a dump maybe it's mandatory to update the bad block table inside the dump..

The RT809H and GQ-5X both map bad blocks and program around them automatically. Not complicated at all.

The 9v-12v DC socket isn't used Maalobs

I finally got the "new" chips in my hand today.

They are obviously used and have been desoldered from some other device:


On the first chip:
I dumped the existing contents and verified the dump against the memory contents, they were identical.
I erased the memory and wrote in my "read 3" dump from earlier and verified the dump against the new memory, and they were once again identical.
Looks good.

On the second chip:
I dumped the existing contents and verified the dump against the memory contents, they were identical.
I erased the memory and wrote in my "read 3" dump from earlier and verified the dump against the new memory, and there was 1 bit error.
I read that memory back into a new dump, now it had 2 bit errors compared against the original "read 3" dump!
I wrote in the "read 3" dump into the memory again, read it out to yet another dump, now that dump was identical against the original "read 3" dump.

So the second chip seems to be glitchy already.

At least these are in a far better shape than the original chip.

Next up, dumping both the SPI Flash and the I2C EEPROM as well.
Would be interesting to try that with ICSP actually, since they both have connectors or at least pads for connectors.
I have been studying the instruction videos from iFix while I waited for the chips to arrive.

XGecu released a new version of the software today, and it turns out that they did not add support for the 8 Gbit Micron NANDs as they had suggested that they would, when I emailed them back in April.
I was expecting this outcome so last week I ordered an Ifix RT809H which arrived yesterday, so now I can in fact read the MT29F8G08ABABA chip.

The RT809H is a very different beast in comparison to the simpler TL866II.
A very advanced tool indeed, but sadly the level of Chinglish in the GUI, the documentation, and the manufacturer's forum, is on a higher plane of existence.
Luckily there seems to be a series of instructional Youtube videos from the manufacturer, so maybe the correct usage workflow for complex scenarios can be attained that way.

I guess there are some RT809H owners here already, can anyone please tell me:
1. When do I need to use the 9-12VDC DC-plug to power the device?
2. When used, how many Amperes does the DC power-adapter need to provide?
This basic information is not explained in the "English" version of the instruction, it only states the accepted voltage range and that the plug is center-positive.

Anyway, I noticed that to read the NAND-chip it was sufficient to power the device from the USB-connection to the computer.

I did a series of reads of the chip to different dump-files, with the auto-verification enabled in the software (on by default) and by using the official Ifix TSOP48-adapter.
I noticed that I got a different number of verification errors in each of the reads:
Read 1: 64 errors
Read 2: 53 errors
Read 3: 45 errors
Read 4: 58 errors
Read 5: 51 errors
Read 6: 49 errors

I did a series of comparisons of the reads like this:

cmp -l read1.bin read2.bin > 1_2.txt
cmp -l read1.bin read3.bin > 1_3.txt
cmp -l read1.bin read4.bin > 1_4.txt
cmp -l read1.bin read5.bin > 1_5.txt
cmp -l read1.bin read6.bin > 1_6.txt

The errors are random bytes that from the value difference seem to have a single bit error in each.

I collected all the outputs together and sorted them:

cat 1_2.txt 1_3.txt 1_4.txt 1_5.txt 1_6.txt | sort > total.txt

When I inspected the total.txt file, I realised that there were two different errors happening.
First, there were several errors that were unique, where the byte offset only appeared once in one of the read-files.
Second, the same byte offsets would appear in more than one of the read-files (but not always in all of the read-files), and whenever they did, the value difference against the first read-file was always identical.

The number of errors at unique offsets were:

uniq total.txt | wc -l
129

The number of errors at duplicate offsets were:

uniq -d total.txt | wc -l
81

The basic operation of loading a chip type and reading the content to a file was documented in the instruction manual so assuming that I am not causing problems by user error, I wondered how I would possibly write something correct to a new NAND-chip out of these dump-files.
But then I realized that the data content of the NAND memory is in fact the filesystems of the Linux partitions, so the filesystems have probably marked some bad blocks on the disk already where there is a permanent error, and the random errors are apparently handled as well since the TV booted successfully after I had the BGA reflow done.

It looks like this chip is on the last leg though, and I already ordered a couple of MT29F8G08ABABA chips from Aliexpress a couple of weeks ago just in case, so right now I'm still waiting for them to be delivered so that I can get years more of reliable use out of this TV.

why not.. for more easy way if you place all balls first under loop on the PCB

my English is bad, but i feel that i have a good company..

Re: Philips 60PFL8708S/12 - QFU1.2E LA - Error code 53

Call me crazy but i think my next step could be a home made reballing, the first difficult part is to measure the original balls, i guess a caliper can't do it right but i'm not sure, then i can not use any stancil and place all balls by my hands..

Why don't you contact him and attach a photo of your specific processor?

I have already told why.. For the Console shop i say that i repair for money and resell the TVs, i cant demand big works to others...

I remembered that I had a dusty old firewall device from a dozen years ago stowed away on a shelf, and this particular firewall always ran pretty hot.
I opened it up to see what's in it, and it turns out it had a couple of 54.6mm passive heatsinks with a pretty high profile, complete with the PCB mountings:

That's great, now I have the cooling issue sorted.

As I wrote in an earlier post; this Chinese seller on Ebay replied to me in a direct message that he also sells the Fusion P120 processors:
https://www.ebay.com/itm/Direct-heat...e/273459017141
Why don't you contact him and attach a photo of your specific processor?
He was very helpful in my contacts with him.
My reflow guy suggested to ask the seller if he can ship the processor "pre-balled", he assumed it would be because that's how he always receives BGA-chips himself from Chinese vendors.

Here's a seller in Poland, but it looks like you need a stencil to apply the solder paste yourself:
https://www.ebay.com/itm/FNP102C31-C...1/292955881093

Also, look for PlayStation/XBox repair shops near you, they might have bigger hot air stations and be more experienced in hand-reflowing BGAs because of the heat problems and big chips in the consoles.
That's how I got mine to work on the first try, by not using my own dinky 858D and also letting a professional do the work.

Re: Philips 60PFL8708S/12 - QFU1.2E LA - Error code 53

I have tried twice the reflow but cpu sounds dead, i dont know if i can go further since the art of reflowing is not clear to me, not many experiments done, i have another tv of the qfu1.2ela to resurrect, i can try reflowing on it, after that i can evaluate the purchase of a new cpu, when i was searching for it months ago it was unavailable, asking it to Sigma factory resulted in no answer.. as usual. With a poor 12 euro hot air gun one can't think to solve so many issues..

Re: Philips 60PFL8708S/12 - QFU1.2E LA - Error code 53

Sounds like a bad reflow in your case, or maybe the processor died?

[Davi.p]

Re: Philips 60PFL8708S/12 - QFU1.2E LA - Error code 53

No, it was better a memory problem because the reflowing was the first attempt made 2 years ago, the tv that was 95% time working stopped working at all after it.

Re: Philips 60PFL8708S/12 - QFU1.2E LA - Error code 53

The reflow guy didn't have any programmer at all, he only works in hardware.
I guess I have to wait for XGecu to release the upgrade then, because I haven't found anyone around here who has a matching programmer.

Davi.p what do you need?

Re: Philips 60PFL8708S/12 - QFU1.2E LA - Error code 53

XGecu has already replied to my question about adding support for this 8 Gbit NAND-chip:

will upgrade in next month

Re: Philips 60PFL8708S/12 - QFU1.2E LA - Error code 53

you have allot of free time to learn LOL.. but you can spare it too... NAND-chip will never missed up on any EU / western brand name TV.. Chinese brand name.. yes.. i know you will say fillips all made in china.. but components before selected especially NAND, DDR. fillips should agree first ..
reflow issue accused by:
1- bad PCB material & robot use.. infrared or laser. or hot air
2-use stock soldering material and this almost 70% issue over all PCB not only TV but all audio video PCB platform
