by r2digitalI have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...2 Photos04-18-2024, 03:50 PM

by trepachkaHello, I have the following laptop:
HP Pavilion Aero 13-be0003ca
ProdID: 2L7M8UA#ABL
S/N: 8CG150GPV6
Motherboard information is below:
HP Part# M52826-601

It needs BIOS repaired.
I created a flash drive using HP firmware utility and then had it plugged into the computer. I did the standard WinLogo->B key->Power button press. A window appeared and immediately began flashing the bios using the flash drive.
But I don't think it finished all the way. So, now when I attempt...-

by fedeRaiderHello everyone
My TV no longer shows signs of life, but if I unplug the motherboard, the backlight works.
I bought a CH341A USB Programmer, and this is my dump (BN41-02568B):
Could someone help me fix it?...Today, 06:05 AM -
by mitchwLooking for a BIOS for HP 255 G8 (HPL51 LA-L021P).
The main problem is that the laptop will crash while booting to OS. Will crash even on booting from USB, like a Ubuntu or to a Windows 11 installer.
Before junking the board I would try the new BIOS if it does anything.
Thank you!...-

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 MDSIHello.
I have an Asus X705UV which no longer starts since the last Windows update. I suspect Windows Update of having tried to update the bios and having corrupted it, because currently, I have the charging indicator when I plug in the charger and I have the power indicator when I press the on/off button but nothing more, not even a fan running.
Could someone check this bios and if it is broken, repair it?
Sorry in advance, google translate is useful but not perfect. 😂
Thank you in advance ! 🙏...-
