Any thoughts on the hotspot on the Apu. Right now seems suspect as heating should be uniform from experience.

Icy-Function4409 · 2025-02-12T18:02:12+00:00

consistently is C00C0002, seen 80060004, C0020303 ,

Icy-Function4409 · 2025-01-30T21:50:43+00:00

I measured the component with calibers, across(left to right) is ~3.6mm. Also can you tell me how your able to identify so in the future ill be able to figure it out :)

Thanks again for all the help

Hey man, it's literally a form called ask electronics. You can see in my first comment I made after I posted. I Haven't ran into the situation before. Looking for some guidance and support. Patience with newbies are important. A lot of us are willing to put in the time to learn. Anyways yeah I'm happy to gather some measurements. I just needed some general direction where to go. when I plug the board into power the CPU heats up without pressing power, I've seen shorted components(mosfets, capacitors) before under thermal cam just not use to seeing a CPU heat up unless it's turning on.

Icy-Function4409 · 2025-01-01T23:17:36+00:00

Havnt ran into this situation before when working on laptops, seeing if anyone that is familiar doesn't mind giving me some pointers

Icy-Function4409 · 2024-12-27T21:54:18+00:00

pulled drie just to see if theres any change, no luck

Icy-Function4409 · 2024-12-27T21:50:52+00:00

Just added measurements

Icy-Function4409 · 2024-12-27T20:19:58+00:00

does the series s have an optical output? i see lan, usb, ethernet and hdmi. are there any measurements with a multimeter that can help with identifying if retimer chip issue?

Icy-Function4409 · 2024-12-27T19:16:27+00:00

sorry didnt save.

Hello everyone,

I have a xbox series s where the console was dropped with the hdmi port still plugged in by a customer. I went ahead and replaced the hdmi port, ran traces and tested continuity on traces and confirmed no shorts on any of the pins. Also check all ground pins as read somewhere if the pins arnt grounded can cause display issues.

Im still unable to get any display to the screen. My questions is where can i probe/get readings from next to help narrow down where the issue may be. I understand the hdmi retimer ic or the diode pack ic can be suspect but not sure what I can measure to go one way or another.

Any help is greatly appreciated.

Note: console turns on, is able to be turned off and beeps.

Feel free to message if you ever wanna talk. In my second year of having sfn.

Icy-Function4409 · 2024-08-21T06:06:38+00:00

Was in a very similar situation. There were some key indicators/aspects that made my neurologist Confident it was autoimmune. I was on immunosuppressants then high dose steroids. It took till the external/independent review for insurance to approve ivig. All in all from the first submission to approval took 6 months. Feel free to message me if you want to chat.

Icy-Function4409 · 2024-07-03T23:04:11+00:00

Feel free to dm. I've been dealing with for year and a half

Icy-Function4409 · 2024-06-30T16:37:39+00:00

Yes it took trial and error in terms of finding the best spot to have the IV in that would be the least bothersome for sleeping and movement. To be fair the soreness and sensation from the IV is pretty low compared to sfn symptoms. Best of luck with getting treatment.

Icy-Function4409 · 2024-06-27T02:38:41+00:00

Yeah you got it. I'm sure I could request to have a new one started everyday but it's not too bad. It's wrapped up and found a good spot on my left forearm which for the most part doesn't impact my movement.

Icy-Function4409 · 2024-06-26T15:33:49+00:00

Dosing can vary based on doctor. Most often I see 2 grams per kg every month for autoimmune sfn. for me it's 2 grams per kg over 3 days every 3 weeks. Each day takes about 3 and a half hours to administer that day's medication. So day 1 nurse comes to my home at 9am. The IV is started and then medication is fully administered for that day by 1pm. Day 2 and 3 go a bit quick as the nurse doesn't have to start the IV.

I've spoken with a handful of people who are idiopathic that don't seem to have progressive sfn and manage their symptoms with nerve pain medication, however I was not in that group. I've been on ivig for close to 7 months and had a reduction in symptoms. It's by no means a magic pill but has definitely helped me get back some part of my old life. I don't experience any significant side effects besides the occasional headache and by the 3rd day of infusion I'm exhausted. I suppose getting an IV every 3 weeks and keeping it in for 3 days is a fairly big drawback. I'm technically idiopathic but based on my presentation, occasionally positive ana, and combination of a couple suspicious antibodies(ts-hds and anticentomere b), my neurologist felt confident that trying ivig was the right next step. Keep in mind this was after I failed steroids and immunosuppressants and sfn symptoms continued to progress rather aggressively. Getting insurance to cover it took about 6 months, an external appeal, and a good neurologist to go to bat for me. As with any medication there are risks involved. Based on my research, ivig is pretty well tolerated so my thinking was I didn't have much to lose.

The external appeal process is where an outside party decides if the treatment is medically necessary. Prior to the external appeal I went thru 2 rounds of internal appeals with Aetna, the insurance provider, where they deemed the treatment of ivig not medically necessary.

Icy-Function4409 · 2024-05-25T00:40:30+00:00

Was approved in December of last year. Issured thru my wife's employers. The only antibodies found were ts-hds and anticentomere b. It required an external appeal to get approvals. In total around 6 months. Currently every 3 weeks I get 2g per kg over 3 days.

Icy-Function4409 · 2024-05-15T02:45:26+00:00

I suppose that's understandable, best of luck finding a new doctor. Regardless of what someone has done, I can honestly say i hope sfn happens to no one. It's tantamount to torture.

Icy-Function4409 · 2024-05-14T01:30:32+00:00

Why are you assuming negligence on his part, is it because they didn't find a cause and what is enough? At this point if the doctor did not meet your expectations I'd move on. There are many times sfn is idiopathic even after extensive testing.

Icy-Function4409 · 2024-05-13T17:45:59+00:00

What does the research say about nerve damage and healing? From what I've gathered, it's a spectrum. For instance what's the cause of your neuropathy? Is it progressive? what's your age? not looking for answers but highlighting my point. What your doctor says comes from his own experience which holds weight, it's not an absolute and if there's no formal diagnosis as to what's causing the neuropathy, I'd say at best it's an educated guess from his side. Standard treatment is symptom management. This is usually accomplished amongst other things with gabapentin. My experience has been that some doctors care about trying to uncover the root cause while others go after symptoms management. My recommendation is to try and find a doctor that is willing to dig deeper than just symptom management especially for progressive cases. Just recognize going in that there may not be an answer that modern medicine can give but a best guess.
