Make sure you tighten the 11 black screws that bolts the backlight plate down before you put the diffuser back as these screws come loose very common on these Sonys

Great video. I replaced the backlight led's but now getting sound but no video - any ideas ? Connectors are all good. Thank you!!

Many thanks for the video, is the white tape next to the LED strip needed for light reflection and is it a special type of tape?

very helpful vid, where did you get the led replacements?

This happened to my 55x8509c yesterday, I've had it since April 2016. I unplugged everything from it, plugged it elsewhere and it continued to flash 6 times after leaving it. It's now working (pretty slowly) this morning. I wonder if it's fixed itself or if it's done lol

I have the same tv with 8 red blinking lights. Is this the power supply. Any advice would be great.

Where can find you

I need KD-49x8500c edge led. Please help

Do A4 blinking light I have a Panasonic plasma. Thank you

Is there anyone in the UK you can recommend for this type of repair and what should I expect to pay? Or is it a job I can do myself with the right tools?

Before i take my tv apart, i need to ask; is there more than one set of led strips on this tv? Or is there only backlight leds on the top edge as shown in this video? Flickering on my tv backlight was only on the left hand side of the screen after about 4 hours of the tv being on, is there a way to test these LEDs?

I have replaced my but not more than 2month it happens again

Very helpful video, thanks a lot. I just did the repair but after that the upper part of the screen is much darker than the lower part. Maybe I did some mistakes with assembling one of the foils. Have you some advice? Thanks and best regards

Hi, do you know what the 8 blinking lights error means ? And what parts require? Great video 🤙

About how much to repair this set please.

I got a quote for a repair 350 plus because the t con board blew too. Absolutely gutted as my mam just came home from hospital and now I’ve no tv in the sitting room for her

Just ground BKL-ERR cable and done

My set is working fine for ~3 hours, then shuts off with 6 blinking lights. Works fine again after cooldown period.. Service menu says backlight issue it doesn't make sense.
