I have a Sanyo FW55D25F with a power light when plugged but no picture or sound. The screen flashes on when I plugged the tv in but immediately goes right back off. I'm thinking there may be something going on with the main board. Any other ideas?

I replaced the mainboard f that fixed the issue. -
Re: Sanyo FW55D25F
Well, I thought replacing the mainboard had fixed the issue. The tv worked for today’s with no problem. I returned it to my friend & it hasn’t worked for a few days now. It was struck by lightning when I first received it. Now it’s back doing the same thing. I have to figure out what is causing the mainboard or the EEPROM to fail.Comment

Hey All!
Long time forum member here with a problematic laptop issue!
I got a RZ09-0196 with a bloated battery (still worked and charged fine) I pulled the old cell pack out and installed a new cell pack in its place.
The laptop would not power on with the new battery installed without the power supply being plugged in.
When booting into Win10 (all up to date BTW) I saw the battery icon with 49% plugged in not charging.
TL;Dr version, old battery worked, charged but was bloated, installed a new non OEM replacement, laptop/windows... -
Hi everyone,
I've got a little "problem child": my Dell Latitude 7420 2-in-1, which had a faulty mainboard.
I replaced it, but ever since, the touchscreen no longer works — and honestly, I’m running out of ideas…
In Windows Device Manager, I just see an I2C HID Device with error code 10. Sporadically, the touchscreen is recognized correctly for just a few seconds, but I haven’t been able to determine under which circumstances this happens.
The touchscreen also doesn’t work in UEFI/BIOS, although it’s enabled... -
Hello,
I have an old MASTER TL-240 LED TV. Since it stopped working and it had a DVB-T receiver that is being dismissed in Italy, I've decided to replace the mainboard with a DVB-T2 one.
The original problem was that when switching on the TV, the power LED was transitioning from red to steady blue, without showing video or audio.
After checking some voltages on the power supply board (HKL-240101-B Rev. 1.4, HKL from now on) someone suggested me to replace the mainboard.
Now I have some doubts about how to connect the new mainboard to the old power supply.

I have Sanyo 55" TV that randomly shuts off..
Sometimes it will stay on for 5mins or so, sometimes it shuts off after a min or two...
When it DOES stay on, it works fine...
All things being equal, would it be more likely a POWER Board issue or a MAIN Board issue???
Thanx in advance...... -
Hi everyone,
I'm trying to repair my LG 49UB850V TV (WebOS 1.0, UHD model from 2014).
Mainboard model: EAX65684604
PCB marking: EBT62954607
SPI chip: Winbond W25X20CLNIG Problem description:
Originally, the TV would turn on (backlight and LED OK if I force them on), but it shut down as soon as any input was received from the IR sensor or remote. The backlight and power board were working fine.
After testing and verifying the voltages (DRY ON, PWR ON, 12V/24V rails), I suspected a corrupted SPI firmware. What I tried so far:- I bought another
