Re: Apple Cinema display 23" ... detection problem
maybe it's related to pins not used in that monitor.

Re: Apple Cinema display 23" ... detection problem
ah, ok, that can be the case.
I've ordered some of those IC's so I'm going to replace it anyway... maybe it has a function so the chip has to be present.
I know of a few other identical display's which has problems with the Tcon board... I wonder if this short to ground is a regular fault with these screens.Comment

Re: Apple Cinema display 23" ... detection problem
Yes, I believe it's an LG.Philips LM230W02 IPS panel.
It sure has a very nice and bright picture with very natural colors.Comment

Re: Apple Cinema display 23" ... detection problem
Hey Porto, we're probably not talking Schmitt trigger but EEPROM here. I wonder if it's U8 you've removed. I believe U8 is an EEPROM responsible for communicating EDID info to your computer with the monitor still switched off, and PSU checked out as functional.
Once the monitor is properly switched on, I think U1 will take over EDID info over 2 wire serial com (SDA +SCL)

Re: Apple Cinema display 23" ... detection problem
Nej snakke Norsk, Svenska, Dansk, but I've got the drift... Sorry. English my pleasure.
Although "Nederlands" is not to be counted amongst the "Northern Germanic" aka "Viking" (no offence intended) languages Philips I2C is included in the DVI protocol as a "2 Wire Protocol", carrying SDA (DDC Data) and SCL (DDC Clock).
Best read my post #27 here on the subject.Comment

Re: Apple Cinema display 23" ... detection problem
Hoi!
Nope, I removed UD1 on the Tcon board, it was shorted to ground.
I don't think it's an EEPROM, but why it's there, beats me!
Helaas mogen we hier geen Nederlands praten, vindt Budm niet leuk!
(Unfortunately we are not allow to speak Dutch in here, Budm won't be happy about it! )

Hello to all,
I have a problem with monitor that is delivered together with CCTV system.
The monitor appears to be completely dead, there is no LED power diode and it doesn't react to pressed power button.
I have disconnect display and check many components on the power supply part of the board. There is no anything obvious and monitor is about 3 years old. There are no bulged caps. When measuring voltages on the output connector to VGA board I can measure stable 14.5 V on 12V pins and stable 5.07V on 5V pins. So I assumed that this part of the board is OK.... -
Hi there,
I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.
You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.
This daughterboard uses an interesting...04-21-2025, 11:41 PM -
I have an intermittent display problem with my monitor, when I plug in the HDMI cable to my (or any) laptop, you see the connection screen shrink on the laptop as it usually would before displaying on the monitor but 95% of the time the monitor display stays black.
Before it cut out all together, tapping the monitor control button a fair few times would make the screen display, and everything work fine.
But now it never does it. Not sure what's going on, hoping someone can help. I'm capable of stripping the thing down and soldering in new parts if needed, or programming...04-24-2023, 04:33 PM -
Hello
I have since a long time a Philips HTS8010S/01 which has been old but was doing the job.
Since a few days, it starts by making a weird "static" nois when switches on for a few seconds to a minute and then works like a charm.
Noise loudly outputs from the 3 channels, even if no signal is sent by the controler.DVD to the subwoofer/amp unit.
I was thinking of a soldering that was starting to be damaged and that was only doing the job after a few seconds of heating, most probbaly on the power board

I have a few successful experience in fixing tv backlight problem. But for monitor, I have no experience. However, I think they are more or less the same. Am I correct?
Recently, I got the captioned monitor and the owner said it could not be turned on. I open it up and found that one of the SMT capacitors seemed to be bad. I replaced it as well as the other one. The monitor still could not be turned on.
I found the power indicator is on. When I shine a flashlight on the screen, I can see the image. Therefore, I think it is with backlight problem. I took out the led strip....10-13-2021, 01:52 PM
