So you get the exact same picture with both replacement boards?

Re: Sony KDL-40hx723 5 blinking lights.
You probably shorted something out on the driver board between the tcon and panel, strip it down a little to get to the board for testing, youtube may have some good videos.Comment

Re: Sony KDL-40hx723 5 blinking lights.
If 5 blinks is Tcon error, check for 12V on both sides of tcon fuse. If not present, check the SMD fuses on the main board since the 12V is switched from there. Bands/stripes are panel damage and may be unrelated. Do they appear with your old tcon board? Sony service manuals can be found online with schematics so you can trace the 12V supply to the tcon on the main board.Comment

They appear on both the old and new t-con, they just change the location when I change the t-con. Is the 12v on the fuse suppose to be there even when the tv is not on?Comment

Re: Sony KDL-40hx723 5 blinking lights.
Yes it's the same part number. Surprisingly at one point the tv powered on upto the sony logo for about 3 seconds but the letters of the word "sony" were inverted ,more like they are being viewed in a mirrorComment

Did you go by the P/N as printed on the barcode sticker or by the number as printed on the board?

I have a 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

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,
I've got a Sony KD-49XE8396 TV that will switch on show the Sony logo then the Android logo and then switches off, and then blinks red 6 times.
I've read that this is the backlight, and during it showing the initial logos I can see that the left side is definitely darker.
I've also read that you can bypass the error to get it working but I'd prefer to fix it if at all possible. Any help would be appreciated.
Many Thanks in advance. -
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... -
