Macro-blocking from CAM module returned for XH90

aimesilenz1 — Fri, 22 Sep 2023 00:09:26 GMT

Hi,

My XH90 (KD-55XH9096) started to experience the macro-blocking and stuttering problem while CI+ card is inserted. The problem appeared with update v6.2126. The newest update v6.2146 did not resolve the issue. I know that the problem should have been resolved in a previous update, although I hadn't experienced it myself until now. Has anyone else encountered this after the recent updates? My local Sony support (Romania) wasn't very helpful and recommended me to contact a repair shop (even if it is a known issue with the CAM module) or wait for a new update which may or may not include a bug fix (asked them to forward it to a specialized department, but I don't think they will).

Hi,

Did you try to unplug your TV from the mains for 2 minutes and test the TV without any external device connected? You can also try to factory reset, it usually helps with issues related to a software update.

Hi,

Thanks for the suggestions. I've already tried unplugging it, but didn't have the time or patience to do a factory reset. I have toyed with all of the settings and there is no correlation whatsoever. Lately I've noticed an amelioration of the problem on some channels and an exacerbation for others. I'll wait and see if the next update solves the issue. If not, I'll try the factory reset.

Hi,

A factory reset can efficiently eliminate a possible glitch that might be causing this to your TV. I'd recommend that you try

UPDATE

All channels are unwatchable with CI+ card inserted.

I've tried the following:

- Updated to v6.2210;

- Factory reset;

- Changed CI+ card;

- Cable company technicians came and tested the signal. All was fine. Recommended using a newer version of CI+ card;

- Changed to newer version of CI+ card.

None of the above changed the behaviour in any way.

This is a disgrace from Sony, irrespective of whether it is a hardware or software related issue. This started not even 6 months after the 2 year warranty expired.

Hey aimesilenz1, it sounds like you already been in contact with Sony support? What did they tell you?

From where I see it, it sounds like a hardware issue that needs a repair.

I have the same problem. Also from Romania. Sony KD-43X81J. 3-4 weeks ago I noticed macroblocks on HD channels, encoded and not encoded (the ones that I am able to see even without the CI card). I changed the coaxial cable with a new one and replaced the connectors. The signal quality is 96% (I use one splitter) and I still have a lot of macroblocks. I plugged the tv directly in the fiber-to-coaxial converter, the signal is 100%, still macroblocks. Only when the CI card is in place. If I remove the card, the HD channels are fine. Tried rebooting (not resetting...) the tv, resetting the CI card from the provider's app (digi romania) , nothing changed. I have two CI cards, on 2 tv sets. I plugged the other one in the sony, still macroblocks. The other tv (an older fullhd Samsung) is fine, no problems with it. So the issue is with Sony and the hardware or software of the CI cards from my cable provider. I hope Sony can fix this quickly. I have the tv for two and a half years and I was perfectly happy with it, until now.

@ionut_d_m, did you try to unplug your TV from the mains and let rest for a while then reconnect it, also, check if the TV software is up-to-date v6.7546

Re: Macro-blocking from CAM module returned for XH90

ionut_d_m — Sat, 13 Jul 2024 19:12:11 GMT

Hello. The software is up-to-date, I have the version you specified.

I already tried unplugging the TV, but I will try again and come back with the result.

Thank you.

I tried unplugging, it didn't work. I guess I'll wait for a software update. Thanks.

I'd recommend that you go for the factory reset as well, if the update didn't solve the issue

I have the same problem, Sony under warranty suggested replacing the motherboard, obviously they know about this problem, the sad thing is that the second SONY TV already has the same problem!

Re: Macro-blocking from CAM module returned for XH90

ionut_d_m — Sun, 28 Jul 2024 15:42:41 GMT

thanks. I will try the factory reset. Of course, that means I'll have to reinstall everything...

@Petro_cz it doesn't bother me that much, for now. Replacing the motherboard doesn't look like a simple thing, the tv is less than two years old and I have no other complaints. The thing is, it seems more a software issue, not hardware. Now, without the Ci card, I can watch all the free HD stations. With the Ci card inserted, all the HD programs produce macroblocks, even the ones that worked perfectly before (without the card). The Ci card in my case is only for HBO and other encoded programs, but I have a lot of HD programs working perfectly without the card. And, what is more interesting, the TV and the Ci card worked perfectly together until two months ago.

I also strongly believe that it is a software issue, given that multiple models are affected in the same way. If it is hardware related, it means that Sony sells faulty devices from the start. Either way, this is how you lose faithful customers.

By the way, after a few more updates to the software, still no change in my case (KD-XH9096).

My TV is under warranty, so let sony take care of it!

Have the same problem on the uk with the KD65XH9296

Sony support is clueless and unfortunately mine is no longer in warranty. All channels including digital ones are badly pixelated when the CAM module is inserted. It’s clearly a software or motherboard problem, it’s like the communication with the CAM is taking up too many resources and slows down the decoding resulting in that problem.
the strange thing is that this appeared one month after I first installed the CAM. Not sure if there was an update for the tv or the CAM at some point that created this.

anyone experiencing the same?

Hi @maticardi, make sure your TV is updated to the latest version: https://www.sony.co.uk/electronics/support/lcd-tvs-android-xh90xx_x90xxh_x91xxh_xh92xx-series/kd-55xh9096/software/00349314 If the issue remains, use this link to locate the nearest authorised service centre to you and arrange a repair: https://locator.sony/en_GB/servicecenters/?zoom=15&latitude=53.3418405&longitude=-1.4778928

Hi @Gabrielgxa88, did you update your TV to the latest version? You can use this link: https://www.sony.co.uk/electronics/support/oled-tvs-android-a80j_a83j_a84j-series/xr-65a83j/software/00349372 Does the issue only happens when CAM is connected?

Try the steps below and test again:

Remove the CAM module of the TV.
Tune to an FTA (Free-To-Air) channel (so the TV picture appears).
