Good clear pictures of what we are dealing with? We need to see how all the boards are connected together.Never stop learning

Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
The TV shows a black screen with no image.
TCON ribbon connectors were disconnected individually for image and there was no half image even.
Later both ribbons were disconnected and TCON voltages were tested.
12V, 3.3V, 1.8V were seen present but VONE signal reads 0V.
There is also a short to ground in this circled inductor.
Is this a TCON issue or something else ?... -
Hi,
I have this problem with my Sony 55' AG9.
It flashes 4x.
I have found the service manual, and seems it is the TCON.
Before I buy a TCON can someone check the vid?
Thanks in advance!... -
Hi.
I'm working on a Sony KDL-49WE663 and when I first turned it on it was blinking red 6 times.
I opened the TV and saw an inductor was fallen off the power/LED driver board so I soldered it back on and tested again, TV turns on and seems fine but the inductor heats up really fast and fell off again.
Then tested the backlight LEDs they all seem fine with LED backlight tester, every LED lights up. I even measured current draw to all individual LED which was around 27 mA.
Haven't found any shorts after hours of testing.
Inductor is about 4.5 Ohms.... -
It's been a while since I've checked in here or needed input on narrowing down what to replace on a TV repair, but I've got one on my bench now that has me wondering. The lack of part (board) availability means I may need to do some component-level diagnostics, and a second opinion is always good when it comes to that.
The issue - Sharp LC-80LE844U does not display. Power light comes on for a while, then you can hear a relay click off and the light blinks twice slow, then five times fast. Service manual points to 'Panel Power Supply Error' with this code, but isn't much more help...
