Re: Westinghouse EW50T5KW - Backlight but no image
Fair enough, how can I test them though to see if that's my problem? Driver board is the same model number as the TCON T500HVN01.0Comment

Re: Westinghouse EW50T5KW - Backlight but no image
Bump. I ordered another TCON board like a dummy and it fried again. I thought there was a slim chance I was accidentally shorting the TCON out on the metal casing but that was just wishful thinking. I really want to get this TV working as it is my personal TV that I bought less than 2 years ago.
How can I figure out what keeps blowing my tcon board?Comment

Re: Westinghouse EW50T5KW - Backlight but no image
I'd hate to junk this TV so I'm just gonna put it on the back burner for now. Maybe I can fix it once I have more experience under my belt.Comment

Hello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged... -
Dears, this is my first post here and first try to fix my own laptop Apple MacBook Pro Retina 15-inch Mid 2015.
I have some general electronics troubleshooting experience and still as my hoppy but this is my first laptop trying to fix.
History: my laptop backlight stopped working without any reason.
Symptoms:
I have image on screen using my flashlight.
I have fully working laptop with the help of my external SAMSUNG LED tv via HDMI cable.
Keyboard backlight still working and can be adjusted normally.
Since two days I tried to follow all similar... -
This chinese all in one computer gives an image when connected to an external vga monitor but only the backlight with integrated monitor (no image). Initially I thought it was an edid problem on the eeprom of the screen but then I saw that the monitor works correctly with another identical motherboard (model th410-d4, read by bios). Unfortunately the motherboard is chinese and has no brand or codes on the pcb. The format seems ITX. Nothing can be found online. The official yashi site provides drivers but not the bios. The electrical diagram is obviously unobtainable
The board is equipped...01-16-2025, 03:54 AM -
Hi all
I have a Macbook Pro A2442 with the 820-02098 from a friend which has no picture on the display, however, the backlight works.
He was streaming a football match on a questionable site, then the site crashed, and the problem emerged.
Initially, he sent it to apple, who quoted him £1323.95 to replace the display, lid angle sensor and top case.
Obviously, he decided against this and gave it to me so that I could have a crack at it.
From initial diagnostics, I connected to an external monitor, I first tried with a HP 22W monitor, and I booted into the boot menu... -
Hi everyone!
First post on here so do tell me if i'm doing anything wrong. I have a laptop that came in with a broken hinge, but a healthy LCD. We replaced the LCD rear cover and now we do not get an image on the LCD anymore, though we get one via HDMI. There is sadly no schematic or boardview available for this motherboard (Bucks U42 DIS 17817-1) as far as i can tell, but I was able to identify which of the important pins on the LCD eDP connector (30 pin 2 lane) correspond to which pins on the motherboard display connector (which is 40pin, 30 for LCD and 10 for camera/face rec etc)...
