That's without anything hooked up except the power cable. Even with either HDMI hooked up, the image is still messed up. I can still play a game, but it is nowhere near completely functional.

Ok, maybe it related to an error writing the eeprom or a totally different problem. Try verifying if the eeprom read match against the binary file.

replaced the motherboard...and this is what comes up. I can navigate fine on my ps4, but the whole image is distorted. Is this another eeprom problem, or did I not hook up the mobo correctly?

Hi lionitusofsparta, it looks like a HDMI problem, because the menu is showed ok, that mains that part of the image processor is working fine. Try the other HDMI, try using the composite input, and also try with other cables.

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash

yo lo solucione con dos ventiladores en la parte trasera. a los pocos dias de solucionado el tv me dio pantalla negra en algunas ocasiones, luego de los ventiladores jamas, puse uno que saca en la parte de la fuente de alimentacion y el otro que entra aire en la parte de la grafica.

Hola warmachine, sabes que con el estabilizador después de un tiempo me empezó a pasar de nuevo la pantalla negra y a hacer un tembleque vertical. El problema fue que estaba usando un cable HDMI barato, volví a poner el HDMI original que viene con el monitor y por ahora no me volvió a aparecer. Leí un articulo que dice que el efecto pantalla negra podría suceder por desincronización del protocolo HDCP.

Hi All, after several days of happiness with my resurrected 3d display, it started to flash a 1 second black screen, I decide to connect the 3d display to an electric stabilizer that the black screen does not happens any more.

Hola a todos, después de unos días de felicidad con el display 3d funcionando, comenzo a mostrar la pantalla negra de 1 segundo, le puse un estabilizador de tención y listo, nunca mas pantalla negra.

Saludos

Hi Lionitusofsparta, I did the second approach the R_J mentioned, I cut the old eeprom with a pliers, and after a remove the eeprom body, I used the solder to clean the contacts in the mainboard. Regards

I was helping someone get his programer to work, If you are having problems replacing the little 8 pin chip, there's not much I can do to help. If you are having that much trouble I suggest taking it to someone that can do the job for you. I just unsolder the 4 legs on one side with a soldering station iron, while lifting the ic slightly with a dental pick or something simular, then heat the other 4 pins and the ic is out.
Or you could cut the pins off the ic using a knife (don't cut the pc board traces) then using a solder iron heat and remove each pin, clean up the solder pads, place the new chip and solder it in place.

Hello all. I have just finished burning up my second motherboard trying to repair my PlayStation 3D Display. I have continued to burn off the small connectors on the mobo trying to desolder the bad chip. I'm at my wits end! R_J can you help me out, you seem to be the SME on this topic?! Thanks in advance!

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash

Hi R_J

Haven't touched it yet, tied up with family and job, I'll let you know soon on what's the outcome.

So from what I understand,

My board is 08E1-0DM7200 and my old and new chip is 25L6406E
My firmware is this U4 25L6406E_08e1-0dm7200.zip

Just replace swap/replace the chip and its all good?
No power reset/discharge or what so ever?

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash

Did that get you fixed up?

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash

Thats because your chip is mounted wrong on the adaptor (I used a zif socket) The adaptor is in correct, but the chip needs to mounted the other way. If you check the adaptor board without the chip on it you will see what I mean, or look at the picture I uploaded
I hope you did'nt damage all the ic's.

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash

Hi,

@R_J

I'm getting "Write operations timeout failed!" I am using, ch341a v1.17, provided by you, and I attached a picture of how I set the programmer and the chip.

Driver is USB(used your package) OS is Win XP.

Seems that the chips isn't being detected. I tried all 5 chips I bought.

Hey, look this video about repairing Samsung TV replaceing/reseting the eeproms and also see the comment

"@skovdenmark Thank you! Yes, That's correct. Sometimes Eeproms corrupt or fail and require reset/replacing. It's worth trying to reset the eeprom more than once, if you are still having problems. I had to do it twice for it to take effect, however first time I made the mistake of trying to power on the TV, the second time, only gave power to the TV and left it in standby - this worked."

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash

Yo la saque perfecto, pero no me la lee el programador. No se si estara mala o no la soporta. Sabes si la mayoria usa la misma o pone una nueva? Es comun que se corrompan, pero que no sirvan mas es raro.

Gracias

Federico.
