Re: RCA L37WD12YX1 Takes several attempts to turn no.
You have a small seperate 5v stand by board in the set. Could be either of these listed here.

RCA LA60691121 SMPS P-SMPS Board
RCA 274595 SMPS P-SMPS Board for L32WD12YX9
The last one I fixed not only had bad caps in the main SMPS but also on this board. The cap I found was not buldged but read bad with my blue esr meter. It was the medium sized cap next to the transformer if memory serves correctly but check...

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash
I too, tried to see the reaction of the set without the eeprom and it does the exact same symptoms so there is no doubt really, that we are looking at replacing eeproms on these. Just need someone to take the initiative to burn and sell em. If someone decides to do so, please pm me with information to purchase. Thank You!

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash
The monitor I have belongs to a very long time friend. I will likely (not charge) him for diagnosing it because he does a lot of things to help me out as well. My goal is to determine why it does what it does, pay attention to what goes on in other sets and connect the dots. So far, I see a correlation between this device and what is transpiring in the Vizio sets. The only way I was able to determine what happened in the Vizio sets is to swap eeproms with known working ones off similar models. The result was a tv that came...

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash
Mine also only has a red dot for pin one so it's fairly obvious that the Ebay poster doesn't want to give a clue to his fix.
As a repair guy, I half understand that but, it's also another issue when this stuff ends up in landfills because folks have jobs in engineering that truly don't deserve them either.

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash
Either way, if you don't possess a programmer, got to get it from somewhere so no matter how you say potatoe, we still need a replacement lol.
Also; why is this particular eeprom so easily corruptable?
I'm on the phone with Sony now. They refuse to provide a bin file for reload and claim they don't have one but will gladly fix the product for a nominal fee of couse. No wonder they get sued so often.Last edited by richpart; 06-07-2013, 05:55 PM.

Attaching eeprom datasheet.
I knew something was similar to the Vizio problem. Reference [url]https://www.badcaps.net/forum/showthread.php?t=19666&page=4[/url]

Re: Mitsubishi WS-65807 projection TV
No Power On
Cause 1
1. CHECK IC7A00 PIN 53 FOR LOW LOGIC (0 VOLTS), IF HIGH (3.3 VDC) CHECK FOR SHORTED D9A31 PART # 264P045050 AND OPEN R9A33 220 OHM 1/4 WATT ON THE POWER PCB.
Shutdown at Power
Cause 1
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front...

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash
Those of you who have working monitors that haven't failed should check your eeprom numbers for comparison purposes. There may have been parts supply issues that forced Sony to change eeproms during production runs. Just a thought.

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash
My IC has the same exact number match. Just got a full time job so I can buy more toys soon lol.
Thus far, I've reflowed the balled ICs and , replaced regulators with no change.Last edited by richpart; 06-06-2013, 10:47 PM.

Re: Vizio M420NV problems
Verify both old and new eeprom numbers are exact match. I used an eeprom for testing once that was close but not exact and it produced a reversed picture.

Re: Sony CECH-ZED1U Playstation 3D LED TV - Two Red Flash
Based on all I've read from the group and what I'm seeing with the one I have in my possession , a good start would be to clone the eeprom chip and re-program to another manufacturer's ic. I could be wrong but, my instinct tells me there is a problem with the eeprom ic itself. Unfortuanately, I can't get my hands on a schematic to prove it. Been going over the board when I have time but so far, no cigar. I also do not yet own a programmer to conduct the tests. These boards are made in China so it's not out of the realm to...Last edited by richpart; 06-06-2013, 09:34 PM.

Re: Be careful out there folks (ebay scam)
I stopped using Ebay for parts entirely, too many scammers. Ebay doesn't offer adequate protections for lost time and profits. The run around is not worth it for me personally.

Most will doubt the advice I offer but my advice is proven before I offer it. Einstein was probably viewed as crazy by onlookers but that doesn't mean he was crazy. An dog with an open mind can solve his problems, a dog with a closed mind chases his own tail.

Re: LCD TV turns off randomly
Sorry about the confusion, I have alot of sets to catch up on myself. Keeping up with them is a headache in of itself.

Re: Philips 47PFL5603D/27 lcd panel replacement
Do the panel stickers match? If not, it's risky. The variance lies in the small control boards mounted in the top of the panel. These can be changed during production runs. The circuitry for the main board and T-con have to be compatable or more damage will result.

Re: vizio amber light E321VL
These eeproms are not corrupting themselves. It's happening due to data stream loss.
Believe what you want to believe but my boards, repaired as described are holding up perfectly and it's not by chance.
