A Complete Guide to Fix the Flickering or Dimming Backlight of logitech Z 5500 D Control POD - Page 3

Question is: If it doesnt light up and shows a value on the multimeter is a good thing ?
If u r checking the LED naked.. No, its a bad thing that the LED is dead.

Quote:
Anyways. What happens when the LED lights up when I check it with the multi meter and its soldered to the board? Bad thing or good thing ?
yes, its a good thing that the LED is still alive and it wont light up with multimeter once soldered to the board. but lights up when the POD is powered only if all the 6 are soldered perfect.

Hope that helps,

After 14 hours and 31 minutes of rebuilding the integrated circuit board (fixed the 3 LED's - 3 LED's problem) and soldering 1 billion times some cables that kept disconnecting from the board cuz of the age , here are the results:

1. Powered manually the LED's at around 2V ( They stay ON even on standby but I'm working on finding a switch and place it behind the console)



2. Added a 0.10 A cooler behind the console , connected it to a 3.5 V output,gonna add a switch behind the console to this one too.



3. Placed thermal paste on the 2 transistors and a thin sheet of copper
and ofc duck tape.



4. My dirty desk lol



5. The results:



Conclusion: I'm not so proud of what I done , but I really felt like posting this crap after I was done , just so I can express my pain.
Overall it's a good job considering that I had no light for some weeks.
However , I am not satisfied with the cooler as it is noisy but it does struggle to keep the head dissipated, keeping the wring up, but these blue LED's as they are 2 dark , making my already poor writing nearly invisible, that's why I'm thinking of going back at the shop and buy 6 white LED s lol like the old ones I replaced.

Thank you for your time JMD.

It seems u hav worked hard ateleast to shed some lights in ur POD. GooD work.!!!
Yes you r right. Your LCD writings are just barely visible. As u said 6 white LED's or pale blue LED's would do the JOB..
Anyways GooD Luck Buddy !!!!
And let us know how it goe's...!!

Hi J.M.D.
I read your entire message, I'm very happy you found a way to solve this common problem for many of us.
I comment to you briefly my situation. I do not have my pod now because I am out of my house, my pod have the same problem like yours. Are you sure that with this I fix my POD?, i tell you this because I previously send an email to Logitech and they tell me that this is a problem caused by the led source or circuit driver not by a led. I not distrusted you but I only want to be sure because i can lost my warranty too.
Do you have a good picture from LCD backward?, I think is possible to replace the LCD module if i can see the part number, the pictured showed in your guide is blur and I can’t read the small numbers. I worked before with characters lcds and for this I can know how the data is send it if i can read the datasheet, then I can replace with new one but with another lcd color or led color. Like this





Thanks and sorry for my poor English.

Regards

folksoter,

I would like to know what exactly your problem is. Is it the writings on the LCD or just the LED ??. However in my case it was just the LED as the writings were clean and clear. And if your problem is just the LED, then iam really hoping that the mod would fix it, even though nothing is guaranteed.

AFAIK, the LED's on the POD are in series. So if one fails , then evrything fails. And if its your LCD then some user's have also reported that the LCD writing fails due to the high heat generated inside the POD. So its up to you determine what is causing your problem..

And about the backview of the LCD, no iam sorry to tell you that i currently dont have one taken. Perhaps i can get it done for you soon, when i open the POD once again to install the heatsniks on some red hot IC's.

hope that helps a bit

Hi JMD
The problem on my POD is the same like yours. My display leds some times is blinking some times is dimming and some times is complete off. The text on my lcd is clear and with good contrast, the write text never fail.

What you mention about the led in series make me sense because all the light is uniform.

Please, I would to know two question:
When you fix it, are you found a resistor in series with the leds or they are connect directly to the source?.
Have you measured the voltage Vd of the original leds?

I'll open on arrival at home to fix it and possibly in the future to completely change the LCD. I expect no problems because I think the most hard to do is remove the volume knob and seperate the POD's casin, I would mention my progress and take some pictures.

Thank you for your interest, for your fast response and for your good thread.

Ok folksoter, its exactly the same problem. That means you can also try the same mod without any hesitation..


Quote:

No. There were not any resisitor's around but iam not sure. And i would recommend you to use good quality LED's if you are planning to replace those..

Quote:

IIRC , its 1.4~1.8

Thanks J.M.D.! I followed your instructions and it worked flawlessly. I was a little concerned initially because I used SMD's that are somewhat bigger than the original and I could only orient them facing up, not to the sides.

Sorry to bring up an old thread but the back light for my control pod has gone out. Does anyone know where I can buy replacement LEDs? I don't have any old electronics laying around that I can salvage LEDs from. Thanks.
