I would like to know why this faulty R4118 in a RCA TV CTC146 caused the set to be going on/off at startup, it would not stay on?
Thank You

Hello esteemed gentlemen. I have owned this LCD TV since 2012. The only repair was the replacement of the PSU a few years ago. Apart from that, no issues. Recently, all was working fine until I switched on to see it appear as so. The day before it was working fine. There is sound. Could this be a T-Con board issue? If not, what could it be? Thank you.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi, I've just repaired acer nitro an515-55 with specs:

After night or 2-3hours on first startup laptop shows acer logo, windows circle for second and then screen goes blank - machin stays on but i need to turn it off by holding power, on next startup laptop working just fine.
i've tried different bios, different vbios and same behaviour - clean windows install too.

I have a Huawei Matebook D15, MB DAH98PMBAB0 REV. B with faulty onboard RAM. Laptop starts but when loading Windows instantly gets BSOD's. Passmark Memtest shows multpile faults on test 11. Memory is itentified as 2 modules Samsung M471A5244CB0-CWE, which are available as standard so-dimm. Is it possible to desolder memory from such module and solder it on the MB? How to identyfiy which one on the MB is faulty? -
Hello esteemed members. I appreciate that my question will strike some as being somewhat childishly simple, but it genuine perplexes me! I have repaired several laptops before by removing a faulty capacitor that was short-circuiting the motherboard, whereupon the laptop would then work. For me, it begs the question that, if the current can bypass where the capcitor was when it has been removed, why didn't it just bypass it when it was present and faulty,? I can't get my head round the premise that if the other side of the capacitor is connected to ground, then why doesn't the current simply bypass...
