Re: can you help me identify this component?
Its a diode.Take a look at the white silkscreen below it. D4 is the diode ,the others begin with C and R ,Capacitor , Resistor. -

Re: can you help me identify this component?
The diode is a MiniMELF case, it could be a LL4148. it will check as a regular diode. Best to post some pictures of the boards and one of the complete back of the tv showing how the boards are connected. If looks like the tv has a t-con board, check if it has voltage on both sides of the fuse. the fuse is near the lvds cable and is a white smd usually with a letter on it marking the value.Last edited by R_J; 04-08-2020, 09:34 AM.Comment

Re: can you help me identify this component?
You should create a post in the TV section, put down the make and model of the TV in the header, put down what the TV is not doing, attach good clear pictures of the whole backside of the TV showing all the boards; that will be a good starting point.Never stop learning

Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .

Hi gang, its a long shot, but working on Lenovo Legion Pro 7 motherboard NM-F091, and trying to identify this component near GPU with marking "eHFQH" that is burned and shorting the board. Looks like power management IC
I couldnt find any schematic or boardview. The CPU side also has same chip. Any way to identify this chip? or take measurements from the good chip to determine what it is?
Any help would be appreciated... -
I mistakely pluged 100v japanese retro game console to 220v outlet.
So It seems that glass fuse and varistor have been blew up.
I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
Is there any way to identify varistor type in my sega saturn PSU?
Any reply would be appreciated.
EDIT:
It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage... -
Hello everyone, I'm in the process of repairing a tabletop air cleaner, but am having difficulty repairing a failing LCD display.
3 years ago I ran a soldering iron over the ribbon cable and got the entire display to come back to life. Unfortunately it gradually failed again but this time I wasn't so lucky at getting it to revive with heat.
I believe that I may have gotten the ribbon too hot this time, so I'm looking for an alternative to an LMB202E. Unfortunately I am not having much luck. I did find an LMB202A, LMB202C, and LMB202D but I'm afraid the pin outs are... -
Hi guys , i hope this is the right place , i got Plasma Samsung PS-50Q91H and i need to repair Ymain LJ41-05120A , but those component are burn and i can not identify to replace those part , and the part are blue capacitor and the location are C5105 and C5106 and here i attach the part that need to identify , and one more thing , i also need to replace Zener Diode on location ZD5502 and the part are BZV55C because mine is short but i don't know the voltage because those parts are release with many type of voltage.
