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... -
Hi guys
I just started fixing 4k TV few months ago. so I am still learning a lot
I got this tv from friend complaint is ghosting or horizontal lines on image.
never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
then it started to show the ghosting white image.
I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
it has 3 thin small boards at the bottom of the... -
Hi,
i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
Backlight seems to work, Sound (Setup menu after reset) works.
If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
With my small knowledge i would think at least the cables are good.
Can this happen because of a bad tcon board?
Or is it always a bad/shorted... -
Hi to all,
I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.
I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.
Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...01-10-2024, 01:26 AM -
This TV was showing a fine image and pulsing with a partial double image (offset vertically) every few seconds. I taped 8 clock pins on one ribbon cable from the Tcon to the panel. It stopped the double image, but some pulsing in intensity was still visible. I then taped another 8 clock pins on the same ribbon cable and the image is now ‘fixed’. Although I understand this results in some loss of resolution, presumably because the clock signal degrades as it passes horizontally across the screen.
I am wondering - do these symptoms and ‘fix’ mean that it’s a Tcon fault or...
