Re: aliexpress backlights?
I have bought 3528 3V LG compatible LEDs from Aliexpress seller Songxin Light Store. Pay the extra for Aliexpress Standard Shipping. For led strips, I've purchased a few times from ebay seller meihua361000.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
'Morning,
I get sound and picture when powering on the TV and its stays that EXCEPT that the left half of the screen will dim every few seconds then return to normal while the right side of the screen performs as designed.
Did the soft and hard reset options pulling the plug, using the reet option in the vizio menu to no avail.
I checked the mainboard - found some popped capacitors so replaced it - but that did not change the situation.
I checked the t-con board. It is getting good power. Then I removed one ribbon cable to see if I could isolate... -
Got given this breaker to fix, armature had failed so replaced and the same thing happened.
Its a 240v heavy duty breaker as opposed to site 110v.
The 1st armature was bought from aliexpress and advertised as 240v but burnt out within 2 minutes light use taking the 13amp fuse with it and the 2nd bought from ebay (german seller) started to get very hot and begin to smoke so hopefully saved it by shutting it off quick at the first sign of smoke but have now tested the x2 safety cap and its not reading 0.22uf, much lower.
Theres very little to it really on the...08-16-2024, 04:46 AM -
Hi everyone I have this TV which was dead one day when I tried to turn it on. I've had the cover off and there was just a pulsating/electrical clicking/ticking noise from the PSU. I disconnected the mainboard as sometimes this works to just fire it up with backlights on? That didn't help. Same noise. Then I disconnected the backlight cable from the PSU and the TV came alive. It appeared to respond to the remote and i'm pretty sure it's fully operational when there is no backlight connected.
However, I am in a dilemma.
I tested the backlight outputs with the lights disconnected...
