Hi guys, I recently picked up a free very old sony bravia that would power on to a black screen. I took it apart, cleaned the tons of dust that had filled it, resoldered a few sketchy looking joints on the PSU, cleaned and reseated most of the connectors, and it started working again! But upon testing, ive found that the HDMI is really picky. Only my sony laptop would work with the HDMI on this tv. Ps3= black screen, google tv= showed the splash screen, but after that had a solid grey screen, android stick= scrolling nonsense. What could cause this? The HDMI cable is good. Also the tv takes about 10seconds to turn on, but i would guess thats normal for an old model. Thanks!

Re: Sony Bravia Kdl-v40Xbr1 picky HDMI input
Have you checked the output resolution settings on the other devices? I know a lot of these old 720p sets will not accept a 1080p input at all.
Many new ones will and just scale it. That would be my first guess. -
Re: Sony Bravia Kdl-v40Xbr1 picky HDMI input
If you are treating hdmi as plug and play then I suggest you dont.
I would switch off the set and even unplug it, then plug in the hdmi and switch back on.Please upload pictures using attachment function when ask for help on the repair

Re: Sony Bravia Kdl-v40Xbr1 picky HDMI input
the tv takes 1080p and many other resolutions via the laptop so the resolution is not the problem. the first few times i tested it devices were connected with the tv unplugged. what could be different between the laptop and all the other devices ive tried? ill take it back apart again and reseat the connector and measure the voltages to the hdmi chip.
Edit: i havent taken apart the tv yet, but i tested two more laptops, another sony and a toshiba, and both worked immediately. whats the difference? maybe the laptops ground a certain pin or something?Last edited by ivoh; 06-16-2014, 02:42 PM.Comment

I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
I do not hear any sound and I cannot see any backlight.
I have tried disconnecting every cable on each board one at a time to see if anything changes.
The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
My friend ordered another used power supply board but it is also doing the red indicator flash 3 times... -
Hi guys!
I have this old but gold 40" Z4500 Sony Bravia LCD TV that had the first issue with HDMI1 port after a couple of years I bought it (in 2008): I connected a cable from an Xbox 360 to HDMI1 and something went wrong, because from that moment HDMI1 port stopped to work. No audio and black screen appeared.
A couple of weeks ago HDMI2 port also stopped working: I used it connected to my PC with a DVI to HDMI cable. Now, like for HDMI1 port, I have no audio and no video in it. And it's a shame because HDMI2 was the only port to support analog audio in.

Hello,
i have this sony bravia kdl-43w755c which boot loops. After sony logo, it shows the android animation loading then it restarts…
from what i read online it looks to be an emmc issue…
i’m not familiar with this kind of tv repairs… i’m repairing laptops and gpu’s…
i took out the board and say an samsung 16gb emmc
i don’t have an exact replacement, but i have a few 32 and 64gb emms’s from laptops…
i could try to put one instead of the 16gb one, but will it work?
where do i get the software from?
any help will be much appreciated!...03-06-2024, 12:26 PM -
