Re: gateway le 1936 vga symbol shows and then turns off
oooooh kayyy...
Sounds like "2 seconds to black", causes include bad CCFLs, bad transistors, bad transformers, bad wiring and bad caps... among others.
Retiredcaps knows far more about this than I do. A good start would be to remove the cover of the monitor and post pictures of the inside. Don't attach them inline, use "Manage Attachments". Retiredcaps isn't the only one annoyed by this. The wifi in my room is poor, so pages load slowly. Adding images inline makes them slower.Please do not PM me with questions!

Hello everyone,
as stated in the title, my surface 7 pro wont boot anymore.
When i press the power button it shows the square windows logo for a second and immediately turtns off again.
I dont even have a chance to get into bios or boot from usb.
While trying to find help online it was suggested to look for help/repair here on badcaps and it might be a ME Region corruption in bios.
I dont know what that is exactly, but i never tinkered with the bios or windows in terms of hacking/patching etc.
Bought it directly from microsoft and used it now and then and only... -
Hello everybody,
I had this Hisense TV since November 2019 (Bestbuy Blackfriday special). Couple of nights ago my dad turned it off normally. In the morning it does turn on, shows the Hisense logo, then the LED light flashes and it turns off. It remains in the same state.
Things I have done:
A. Plug it off and on.
B. Plug it off, pushing the power button for up to 2 minutes, plug it in.
C. Contacted the customer service, They sent me a firmware update, with the file name:
upgrade_loader_no_tvcertificate.pkg
The zip file has this... -
MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...

I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.
I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue.... -
I am trying to fix my Dynex tv. The PSB is new and so is the Control Board, but when I turn it on, I get "please wait..." on screen, then it quickly goes black. I have the back of it off and checking voltages shows 5v standby and 2.5v supply comes on going away/into PSB/Control Board, 24v is present on PSB (getting .4v on most, if not all, backlight lines, 5v to backlight is there also), the control board's heatsink staying hot to the touch, plus the 2.5v going away/into the PSB/Control Board, gives me the impression it is on. What else should I check for?
