Hi goodday to all.
I really ask for help.
There are two motherboards (absolutely identical) Acer Aspire 5 a515-52g, EH5AW LA-G521P.
Both boards have exactly the same fault symptoms. It turns on, the power indicator lights up for 5 seconds, turns off (the fan does not spin).
Both boards are flashed with Bios Main and Bios EC from the “Bios Acer A515 LA-G521P FULL TEST” topic. XM25QH128AHIG replaced by W25Q128JVSIQ (also NOR-FLASH, XM was not detected by the programmer). On one of the boards, KB9022 was changed, followed by firmware. The fault persists on both boards....Today, 02:41 PM -
by rtstormHello, I have this 55" Philips TV that suddenly has these vertical lines on the LCD panel. I have checked the T-con board and I noticed some caps have 40Ohm I don't know if this is normal. These caps have 1.2V on them. I mark them on the photo with a silver pen. The T-con board has 1.2V, 12V, 25V, etc. Does anyone have any idea what could it be?
i try to disconect one ribon cable and the problem is the same, one side is white other side have the lines (the same is in other way)

by tec3000Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!
I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...03-20-2024, 07:29 AM -
by CanukTukHello,
Kinda new to this, so hoping you will all give me a bit of a pass.
I came to this forum because need to remove the BIOS password on an HP EliteBook 850 G1.
I understand that I need to dumpt the BIOS to a dump file, process the dump file with RCUnlocker, then write the modified BIN file back to tthe BIOS chip.
Is there a beginner guide anywhere that describes the entire process for doing this?
I am reallly in the dark regarding which tool or tools are required to extract the BIOS dump file, then write the modified BIN back to the BIOS chip. The guides I have...-

by EazyBoneSo the one guy said the panel short potentially could be fixed so, here's a TV. TV reboots continuously. Backlights work fine. I put some tape on the top ribbon and the TV was able to turn on and get picture. I attached a pic of which lines I taped as well as some other pics of the buffer boards. Appears the "short" is on the right side buffer board. There are no esd diodes that I see.
Anything can be done?8 PhotosToday, 12:04 PM

by reassorThere is 2 sia ics and in 1 section where u see dots on the coils i have 2.2ohm there and there is no voltage on them at all.
Also i read in other topić how psu works on these tvs and when u pług it in there is constant 40w draw from wall. When I unplug display from tcon it drops 10w when I unplug tcon it drops another 10w (unplug done w/o power ).
I'm mostly sure its main board cpu cause no sygnał to turn on 24 volt for panel and its constant draw.
For now I'm just curios about these w coils . Could not find any datasheet for ic thats the lines go...1 PhotoYesterday, 11:06 PM -

by FronczekHello people,
I've got this laptop not working for repairs, and as you can see something was done to it as you can see in the coils PL58XX (which I for some reason cannot find in the schematics...) The first FET (PQ201) was not an original part and a questionable one at that and the second one (PQ202) was shorted. Both are N-channel. Ordered replacements for them and replaced them after arrival. Now I have encountered another problem: there is no power at the second FET. By following the thread linked I got to the injection part. Applied 0.8V at 1.5A, but couldn't feel anything getting hot,...Technical discussions covering any type of laptop, notebook, netbook, tablet, or smartphone. Any and all brands and models welcome.
