Re: Considering purchasing a Logic Analyzer
Thanks Stj. What are the disadvantages, if any, to using a USB one vs a benchtop model with a built-in screen? I'd like something that I could continue to use for other tasks when I learn more about electronics. You know, something I'm not going to have to replace within a year or so because I've outgrown it's capabilities. I've looked into the USB ones before, mainly because of the price. I've seen with some models, people had trouble with the probes or whatever you want to call them. For example, the one you showed me only has 8 channels. That's probably fine for now, but in a year, I might need 32 or 64. With USB, what would be the maximum speed I could capture at? Would I be able to sample more data with one channel vs all 8? If the chips running at something like 20MHz, would I successfully be able to capture from all 8 channels our would USB be too slow?
On another forum, someone suggested a Tektronix TLA715. I guess right now, I should probably be trying to decide on whether I want one of the less expensive USB ones or one of the mainframe benchtop units or what.

Re: Considering purchasing a Logic Analyzer
Sorry, I should have said more stuff. I wanted to sniff i2C and SPI buses. I want to be able to hook a logic analyzer up to something like my DP832 and see what happens when I power on the unit. I want to see how the different chips talk to each other, stuff like that.Leave a comment:

What sort of bus or digital signals do you want to analyse? This can be helpful in choosing a logic analyser.Leave a comment:

Considering purchasing a Logic Analyzer
Hello,
I was thinking of purchasing a logic analyzer and wanted to know what you guys thought of the Agilent 1673G 34 CH Port Logic Analyzer? What would be a good price to pay for one? I've seen these portable USB ones as well but I'm not quite sure I want to go that route. Does anyone have any experience with the USB ones and are there any general drawbacks to using the USB logic analyzers vs a benchtop model? Thanks!

Hi there, apologies I'm a real noob with this sort of stuff so please bear with me:
A week or two ago my laptop randomly started having the Blue Screen of Death and bootloop every time it booted up. So I tried the recovery options while trying to retain the data: the laptop then said you need a Bitlocker Recovery Key. I never selected for the drive to be bitlocker encrypted so this was really weird to me- I have looked through every Microsoft account I own and none of them have the bitlocker recovery key.
After researching I came across this article: https://dolo... -
I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.
I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.
The models launched in 2018 and 2019 respectively.... -
Hi everyone! I'm trying to fix my black screen / failed U8900 GPU v-core on my Mid-2012 Macbook Pro 15" Retinaby doing a rework/reflow of the chip (once I determine that's the real issue; but it likely is).
I've been disabling the GPU in NVRAM for a few years... but it's just time for a better solution.
I'm new to soldering but the only feasible way to fix this issue is to do something myself.
MY QUESTION:
I've been seeing some people (on this forum mostly) run into issues with the logic board needing a serial number or it being deactivated (?)... -
Hi all, I just want to share the repair of my 60PK550-UA TV set.
The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.
But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.
All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:

Hi dear friends., I am working on a Apple MacBook Pro A1708 , Logic Board 820-00840-A that has no backlight. The logic board powers on fine, but no display. After Checking on the backlight driver chip, I found that the EDP_BKL_EN is missing. And this Power Enable comes from the PCH. So does this means this Logic board cannot be repaired & brought back to life again? The resistance from GRD to the test point of EDP_BKL_EN is around is 0.66M ohms. R8442 (0ohms) is ok. Any suggestion/Tip if any would really appreciate.
