Sony 65X90J, 3 years 9 months ... (note: replace panel after close to 2 years, and replace power board ~6 months later)

In the middle of a watch, the screen is quickly fade to black only sound remaining. Power cycle it doesn't work. The TV can only produce sounds and respond to remove. I tried to see if I can see any image, but using the brightest light on my phone still does not show anything. I put a gentle knock on the screen and can see a burst of light.

My thought
* It's NOT main board: can power on and reach dashboard, response to remote when I change to TV
* It's NOT backlight: ??? since I can't see any display at all. How to confirm this? probably need to open it up, right?

Can it be t-con board only?

@limtk55 - do you provide service?
If not, anyone can recommend repair service?

Looks like no hope. TV panel is gone. Repair with Sony would be ~900 and with only 3 months warranty. Considering both panels failed in less than 2 years, 3 months warranty seems extremely risky.

any idea how much it will cost to repair sony tv? my model is 55X9500G from 2019. currently, there are sound coming from
the tv but no picture at all. called sony support and tried power reset and factory reset but to no avail. dun think is led backlight issue as can see a glow when go to home menu. sony also say the parts are no longer in production.

i am thinking whether to just get x90L during black friday instead of spending money to repair. just getting technician to come down will cost $224, excluding of any parts if required

have a repair guy came down and find out that the tcon board is not working. however, there seem to be a drop in image quality after replacing it. the left and right side are now slightly different. did not went for the replacement in the end. was wondering where to buy the tcon board and maybe i can diy and fix it myself.

I have a 55X9000F same issue as yours. When power on Greyish display panel, front white LED is still lit so there power to it.

I think should be T-CON board related failure, so not sure should I contact third-party for the on-site repair or just buy a new TV since is already a 7 yrs old Bravia.

X90J mainboard died last week.

Kudos to tvpartstoday.com for having replacement parts and highlighting the gotchas of sony hardware. Who would have thought the mainboard and tcon actually need to be paired by updating the firmware.

Shipping was S$70 fedex but all in I spent S$228 (mainboard, tcon, led driver, shipping might was well get everything). I only really needed the mainboard but might as well get the other parts as spares. Skipped power board since it was probably US voltage.

* big warning here: part numbers are not exactly the same. The x90j board they have has 2 extra audio jacks, not a big deal just drill some holes in the port cover.

The bigger problem was the tcon, luckily the old one is fine. Part number different and the power connector is very slightly different. TD001 on mine, the one from the shop is TD00Q. It looks like the pinout is the same so if really necessary can shave a bit of the plug to make it fit, or source another power cable.

If you're willing to try and muscle your tv onto a flat surface and do some surgery this might be the route for you. For $228 and some sweat I felt its worth doing.

Nice - you are very capable. When my X90J died, I got enough back from the warranty to replace it. Good job repairing your kit and extending it's life.

Any idea who can repair lg cx tv burn in

Any idea who can repair lg cx tv burn in

burn in cannot be repaired, short of replacing the panel. try running the pixel cleaning function a few times to see if it improves the situation.

Hey guys, anyone of you have ever requested for repair service from LG?

So i'm currently using a G2, and quite recently, the left side of the panel developed a uniform grey vertical bar on the left side of the panel, with whitepatches permanently etched in along certain parts of it. I think this are signs of OLED burn in on the panel.

Additionally, my TV has also been sporadically shutting off by itself in random timeframes....sometimes less than 10mins, and on a lucky run, it can last 1 hour before shutting down. I've tried all sorts of fixes i can find from online, but none seems to work (e.g. power discharge, disabling CEC, etc).

So apparently i realised that G series panels have a 5 year panel warranty, with free replacement if it's a burn in issue. But have to pay labour and transport costs. I also don't know if the panel issue is causing the sporadic shut down issue.

So now i'm in a dilemma - do i get LG to replace my panel and hope it solves all issues? I'm not sure how much is the labour/ transport going to cost...or how do they even "replace the panel". Alternatively, just write my G2 off and get a G6 (apparently price is quite attractive)...but honestly i'm trying to minimize damage to my wallet where possible.

Is Mr Lim the repair uncle still available?

Panel replacement is costly... if it's under warranty, go ahead, but for such an old panel, that's hard and not cheap..

Hur....G2 considered old panel ah? I thot it is just 4 years old, and very sayang to just get rid of it,,,

1st step should contact LG whether qualify under 5 year panel warranty with free replacement and estimated costs then decide from there

I did actually....was told i needed to pay $218 just for the technician to come down and diagnose the issue.

So if indeed its a panel issue, it will be covered under the panel warranty. BUT, i will have to pay for other spare parts needed to faciliate the repair, on top of any labour and transport charges. This i can only know after the diagnosis. And if the costs are too high and decide not to go ahead with it, i still need to pay the $218.

So it's pretty much a black hole here....the $218 could really be a sunk cost which is why i'm sitting on the fence on this....apparently a new G6 is going for like $3.2k now with $200 grocery voucher....so i'm very tempted to just change...but $3k is still quite some $$$ in days where everyone is tightening wallets (fyi i'm not rich....)

Samsung tv has intermittent sound with red light blinking and no image... It's about 7 years old, is it worth to repair?
