These Hisense H8G series (or Q8G if you are in Canada) tv appears to have a common failure of the main board. Many posts on Reddit without a solution. Mine is a 55" tv hence the 55H8G model (TV comes in 50, 55, 65 and 75". Corresponding models are 50H8G, 55H8G, 65H8G and 75H8G). Symptom is that the tv will not turn on, only a slow blinking white LED near the on button on the tv. Has anyone found a repair for the main board? I can buy a replacement main board, but would prefer to repair my main board. Thanks.

i have DELL INSIPRON 14 5410 2-IN-1 blinking orange and white when charger connected, i tried to find Boardview or schematics but cannot find. i opened the unit and the motherboard model number is 203071-1 Watchmen that i found written on motherboard. Where should i start because when i press power on, nothing happens. but i checked the main power rails voltages are enabled and the charging for battery LDO is 3.3 volts.

Hello everyone
I have this Elitebook that wont turn on, only the battery led is white and blinking orange, does this even without battery.
If this is a error code i couldn't find any info about it.
Already tested with a another charger, measure the presence on 19v on the 19v rail, checked if there was capacitors in short-circuit
Thanks... -
Hello, I have this laptop with a bad motherboard. The LED in the socket is blinking white, endless loop. According to the information I found on the internet, this can be caused by several reasons that I am currently investigating.- Damaged BIOS chip - it seems to be fine, CH341a programmer can read it
- BIOS RTC voltage shorted to ground - it seems to be fine, around 3V
- Damaged adapter identification circuit - I think there is a problem here, but please help explain the function
