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

But, what caused the first improvement in Maalobs TV? CPU reflow or NAND replacement? Since he did both things at the same time, it wasn’t clear to me which one was the root cause. I admit that I’ve chosen the NAND part first because CPU reflow is out of my reach.

Chungalin you are wasting time/money,the problem is the same always, cpu soldering.

Error 2 / 53.

Thanks Maalobs. I have an XGecu TL866II Plus that can read/write these NANDs, but I don’t have a TSOP-48 adapter, so I’ve prefered to order an already programmed NAND for this chassis.

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

Which is your symptom?

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

I still have the dumps of all the flashroms from the TV, even the NAND which is too big to post in the dump-thread on this forum.
Let me know if you need it, I can arrange an sftp link for you.

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

Well, I just wanted to check that I get exactly the same log outputs in both ports than Maalobs. Also, I wanted to make sure that my mods on the standard serial USB adapter were working fine.

I have ordered a programmed NAND and I’ll report results after replacement.

Why you're trying to access standby ser.port? I think it has no useful info in it, i have tryed with a Chinese board theese days, st.by serial only prints few characters at boot and 2 char. at shut down. It is a the port of the st.by processor that has a simple software, not much to communicate..

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

I discovered that the standby processor was set to 57600 8N1.

Thanks. I tried other lower speeds without luck, but not this one!

I use a USB serial adapter with FTDI FT232BM IC and a Sipex SP213ECA IC for standard serial voltages. I disabled the second IC (Enable to GND), and changed FT232BM signaling voltage from 5V to 3.3V connecting VCCIO (p13) to its own 3V3OUT (p6).

The problem is that I tried TXD-STANDBY first, and as it wasn't good looking (due to the speed difference you point out), I blamed my modifications of serial adapted, but after giving up with that port I tried the SERVICE port and it worked fine!

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

Is there any difference between those two serial ports? While I can get clear communication from TXD-SERVICE (with expected parameters of 115200-8bit-1stop-no parity-no flow control), I just get garbage from TXD-STANDBY. I assume that signal level is 3.3V in both cases.

Yes, the levels are 0-3.3V TTL on both ports.
It said in the service manual that the main processor was set to 115200 8N1, and by simply testing other speeds I discovered that the standby processor was set to 57600 8N1.

I used a USB-to-TTL serial-adapter:
https://www.adafruit.com/product/954
This one with the blue casing from Adafruit uses an original chip, so the device works with the official Windows-driver.

If you find one that's half the price or cheaper, then it's most likely using a pirated chip, which the signed drivers in Windows will detect and refuse to work with.
The pirated ones still work in Linux, though.
I learned this the hard way.

I also got a 5-pack of small test hook clips with a male Dupont connector on them:
https://www.electrokit.com/produkt/t...klamma-5-pack/
I soldered a short piece of bodge-wire onto the relevant pads on the PCB and then hooked the test clips to the wires I wanted to listen on.

I left the bodge-wires on the PCB with the ends tucked between a couple of layers of kapton-tape, ready for use the next time.

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

check if there is a level translator like MAX3232 or others..

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

The debug-port 1CV5 is unpopulated but I soldered in wires on TXD-SERVICE and TXD-STANDBY so I could monitor them with serial adapters.

Is there any difference between those two serial ports? While I can get clear communication from TXD-SERVICE (with expected parameters of 115200-8bit-1stop-no parity-no flow control), I just get garbage from TXD-STANDBY. I assume that signal level is 3.3V in both cases.

hulko don't hijack other one's thread with different issues.. open your own discussion

sorry, i see R J's post now..

maki and hulko, start your own threads that way you are more likely to get answers.

Hello, sorry i'm new
somebody can explein how i can activate the service modo on 60PFL8708S
because i'd like to try to re-install the original software before the boot of TV

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

Hello
I was wondering if someone encountered a blank SPI ?
I have a 46pfl8008, it has 2 blinks on level1 and 53 on level 2.
Recovery isn’t working.
I’ve suspected the SPI (25p10) and because it’s the easiest chip to check.
I’ve used this programmer
https://www.ebay.com/itm/CH341A-Seri...53.m1438.l2649

with a clip
https://www.ebay.com/itm/Soic8-Sop8-...53.m2749.l2649

To my surprise, the chip was totally blank – all FFs.
Any ideas?

Hi, I have the same problem with error code 53 with Philips 55PFL8007K12
Chassis / Version: QFU1.1E LA
Power supply: FSP197-4FS01 2722 171 90676 REV: 01
Panel: LTA550HQ19 Card
mother: 3104 308 98314
The TV is completely turned off.
The voltages I read are 3v3s = 3v3 and STB = 3v1
I reprogrammed the spiflash 7CT3 (M25P10),
on pin 2 of connector 1M95 the power supply
it has gone to a low logic level, from 3v1 to 0 volts.
The 12 volt, now, is present,
like the other feeds on the mainboard.
But I get error code 53.
I tried connecting to Hyperterminal at the service jack,
I get this information (see attachment)
I also enclose the Spi 7CT3 reading before programming.
The trash, which I reprogrammed for SPI is for a processor,
is a Fusion P240 FNP202-B1E32.
Can this be the problem?
Another question, why do I get this log with Hyperterminal?

Amennone di plcforum giusto? Qui devi scrivere in inglese! Controlla su plc una disc. recente di Ottaviucci, il problema e' il processore..

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

Salve , ho lo stesso problema codice errore 53 con Philips 55PFL8007K12
Telaio / Versione : QFU1.1E LA
Power Supply : FSP197-4FS01 2722 171 90676 REV : 01
Pannello : LTA550HQ19
Main board : 3104 308 98314
Il televisore si presenta completamente spento .
Le tensioni che leggo sono la 3v3s = 3v3 e la STB= 3v1
Ho riprogrammato la spiflash 7CT3 (M25P10) ,
sul pin 2 del connettore 1M95 la alimentazione
è passata a livello logico basso , da 3v1 a 0 volts .
La 12 volts , ora , è presente ,
come le altre alimentazioni sulla main -board .
Ma ottengo codice errore 53 .
Ho provato a collegarmi con Hyperterminal al jack di servizio ,
ottengo queste informazioni (vedi allegato )
Allego anche lettura della Spi 7CT3 prima della programmazione .
Il bin, che ho riprogrammato per la SPI è per un processore Fusion 77
Mentre il processore sulla main è un Fusion P240 FNP202-B1E32 .
Può essere questo il problema ?
Una altra domanda , perche con Hyperterminal ottengo questo log ?
