Re: Possible purchase but more for my knowledge
I would say LVDS cable or main board issue (possibly unstable LDO or CPU supply), or a bad HDMI cable.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search.

Problem: I need to purchase a mosfet chip from board 820-02100 M1 Pro, that is supposed to be Q5820 but according to Digikey, the schematic diagram I sent them, neither are relevant to the actual mosfet specification I sent them. I just basically need to find this mosfet to purchase, I cannot find it anywhere and am hoping someone could point me in the right direction without have to purchase this entire allusive board. Already checked with Digikey, Mouser, Aliexpress, eBay. Any suggestions?
Mosfet specs are as follows:

I want to fix Video door phone which works its doorbell but it is not able to display any screen.
So I disassembled its plastic case and I detached FPC film cable from LCD display in order to inspect LCD display's PCB
I measured ESR resistance of all smd capacitor on this PCB and I noticed that there is some SMD capacitor which has high ESR value(48ohm 50V 0.47uf,15 and 28 ohm 50v 3.3uf,10 and 8 ohm 35v 10uf)
I desoldered this 5 suspicious SMD capacitor like below screenshot.

hello.
I have Sega Saturn and 5 years ago, I recapped all of capacitor in the Power supply, Because At that time, It frequently freezed black screen after SEGA logo displayed.
It hardly ever freezed after I finished to recap all of caps in the power supply.
But Yesterday, It did not show any screen at all and its green power LED constantly blinked.
To my surprise I found that all of two NXH 10v 2200uf capacitors in the secondary area of Power supply have been bulged and It measured 57 mF and 75 mF capacitance.
It seems that quality... -
Anyone have the esoteric knowledge to know if I can use an older 3580 LCD on a 5410? I do not care about touch capability.
Hoping I can use the FAR cheaper 3580 ( ebay.com/itm/285615245334 ). -
Hey all,
I've got a few XBOX power problems but don't know much about anything concerning electronics troubleshooting outside of replacing caps. Instead of coming on here and wasting people's time being confused when they say check rectifier, transistor, resistor, etc or whatever it may be and then having to ask "what is that?", I wanted to learn and build up a knowledge base first so I'm not completely clueless and can apply the good advice people give without confusing the situation more by not knowing what i am doing.
Is there a good thread or source, either on this...
