XR-65A75K Sony OLED TV 5 times red light blinking

just-ice — Sun, 29 Sep 2024 13:53:13 GMT

My Sony XR-65A75K OLED TV refuses to start when powered only red blink 5 times and repeats the blinking after a pause.

I have tried the unplugging and plugging the power plug while pressing the start button on the TV. This has worked twice with the TV working for a few days and relapsing to 5 blinking red lights with the whole TV not powering up.

Kindly help with some insights to this problem.

Thank you.

Red blinking LED is a sign something major is failing on your TV.

Is your TV still under warranty, if so contact whoever you bought it from and arrange

to have someone come out and check it over.

Have a read of this if,

If the TV is out of warranty then you may find a repair is too costly to justify and a new TV is the only option.

I have finally discovered the challenge with my TV it’s the T-con board but am unable to get the exact fit. The part number is: 6871L-6962B.

Please will appreciate any pointers on where to get one.

Thank you.

@just-ice

I pasted that board number into a Google search. All sorts of responses came up, some of which were relevant.

Thank you Royabrown2,

A bit apprehensive about getting it from eBay which is the major pointers one gets from google search.

Will also take a look at the product manual.

Thanks.

I finally resolved the issue with a replacement t-con board which I got from eBay. The issue was resolved immediately I replaced the t-con board only no other thing was touched.

Though the confusing part was that the part number of the replacement board is 6871L-6962A (6870C-0931A) while the one I replaced was 6871L-6962B (6870C-0931B). I was afraid that the last alphabet had to be the same, and only bought it because the seller confirmed it was for the same model of Tv.

Thank you all for your support. What a relief.

Hi, just an update on this issue, hope this might be useful. My TV also failed with the red led blinking 5 times. As I was going away I unplugged the TV from the mains socket. When I returned home after 3 days I thought I should give it another try before contacting a repair company. To my surprise the TV correctly initiated the restore process and it has been working fine since.

here is how Chat GPT explained the situation:

Here’s what likely happened with your Sony XR-48A90K and why leaving it unplugged for several days fixed the 5-flash red light issue:

⚡ The Technical Explanation

Residual Charge in Components

Even when unplugged briefly, capacitors and other electronic components inside the TV can retain a small electrical charge.
These residual charges can sometimes cause the TV to misdiagnose a fault and trigger the 5-flash red light code.

Firmware/Software Glitch

Sony TVs run complex software that controls everything, including power management.
Occasionally, the software can get “stuck” in an error state, falsely signaling a hardware failure

Extended Power Discharge

Leaving the TV unplugged for several days allowed all internal capacitors to fully discharge.
This effectively “reset” the internal electronics beyond what a normal power-off or short unplug can do

System Reset Completes the Recovery

When you later performed the system reset after unplugging, the TV reinitialized its firmware and hardware checks without any lingering errors.
This cleared the false fault, allowing the TV to power on normally.
