Got a brand spankin' new TCL 65S450F here. Plugged the TV in and it booted up and wanted a firmware update right away. O.k. I guess it did that or not... I got no forking clue. Came back in 10 mins later and the screen is black, backlights on. The Standby light is blinking and every 10 to 15 seconds makes bleeping noises. That's all she does. Tried a factory reset and that must work as I can adjust the volume of the bleeping and it returns to factory volume afterwards. Also tried big black button with the circle right button on the remote and no go.
EDIT: No bootloop the bleeping... -
Hi folks,
I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown... -
Does anyone have high frequency sensitivity hearing and a motherboards have tons of sounds coming from it? Is this just coil whine en masse? When data to the SSD has high I/O I can hear the clicks and chirps. Same with when the graphics drive inits. Network adapters, chirping after I connect the cable
I can hear everything. Every time I put my ear to let's say an open Shuttle XH series pc (currently working on) in the next room it sounds like I'm in the middle of a the fucking public bird aviary
Of course this isn't just the shuttle, though I think the small case... -
I just saved this magnificent RGB input Eizo Flexscan TX-C7 MA-791 from the local e-waste...good news, the tube works and the board looks great...the bad news, it sounds like the flyback is shorted. (Turns on...perfect picture...systemic high voltage crackling heard while the picture flickers...then it blows the 5A fuse in my isolated A/C power supply.)
Anyone have any leads on possibly finding a replacement? (photo shows the flyback model numbers)... -
hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon
not heard of these brands are they any good?
iv attached photos of the charger and the board inside for an idea on the type of...
