When I select low ESR on mouser, I can't get 200V for anything, let alone 47uF. Tried Farnell and Digikey, and not having much luck with low ESR for 47uF/200V. Can probably get from China !Comment

Thanks for that. Got the identical EE series one on mouser. It has a high ripple current, which is all I could find on the Sam Young datasheet. Still categorised as general purpose on mouser.
Any ideas about the HXB marked caps ? They are small 6 x 7mm, so may be able to replace with good quality panasonic and ignore the HXB.

I can't tell what they are from the pictures but you should be ok as long as the uf is the same you can go up a little in voltage if you like just never under, like if it's a 35 volt you can go to 50 but never under 35 volts or whatever the original was.Comment

Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I... -
Samsung QLED QN50Q — purchased 2022 started experiencing a delay in the picture coming on in the morning less than 2 years later. Did not know the term boot loop at that time. As the loop delay ran into a few minutes did all the recommended troubleshooting, soft and hard reset, changing cables and outlet locations, no help. As the delay increased contacted Samsung tech group and allow them remote access the tv. Tech was moving too fast to see exactly what he was doing but this ultimately it was also no help. Lived with the delay until it stretched out over 6 hours. Pulled of off the back cover... -
Hi Team - just joined to see if anyone can offer some expertise in diagnosing an issue with a TV.
I've done a few hours googling and youtubing but just seeing if anyone has any insight here. I got a 55" Samsung UE55MU6470U which seems to boot loop and then after 10 mins will boot, work for a few minutes, then turn off and repeat.
Whilst it's on into the normal Samsung menu/boot screen it looks perfect - so I can't see there being any screen issues. I've seen lots of videos with taping across clock lines to diagnose which particular one may be an issue but i don't... -
Hey everyone,
Usually, I'm not the type to ask for help, but this time, I'm calling on your wisdom and expertise
I've seen what this community can do, so I'm pretty sure you guys can help me out.
Here's the deal: I noticed my MacBook got stuck in a boot loop. After opening it up and doing some initial troubleshooting, I found that the boot loop stops only when the trackpad is unplugged.
Now, just so you know, the trackpad actually works — I tested it with another motherboard and it's all good. Same for the cable, no issues there. The problem is only... -
Hi, I wonder if anyone can help me fix my Lenovo Legion 5 (15ITH6H) laptop. Basically, after a windows update the computer would not boot anymore. When powering on the laptop the screen has no backlight and nothing would show up, using an external monitor did not help. However, the laptop would still spin up the fans and turn on the keyboard backlight. The keyboard backlight intensity function key would work and the power button led and the charging led are also working. I've tried every possible combination of key press and power button hold down time but did not change anything. At this point...
