Nice work, buddy! What are you going to do with the extra power management board?

My 09 kdl 52z5100 240hz still looks great. Worth 2.4k bucks. I'm looking at the Bravia x750h. Only 60hz though

HI thanks for the great info . We have a Sony XBR 85X 850D which was working fine in the morning but when we came back from work was dead and no power or light will come on . We were able to take off the back cover . Noticed there are 4 boards in the back . Tested the 1st board using the multi meter and verified the 110 AC coming in and out . But the 2nd board which we think is the 2ndry power board had 110 Volt coming in but we couldnt verify voltage going out . Now we couldnt test the 3rd( some kind of green tuner board) and 4th board (main board ) . We are in the process of ordering the 2nd power supply board but would like to know how to test the 3rd and 4th board . Any insight in this will be helpful . Donot wanna junk the TV as its just 4 years old and was working fine before went to mars

Backlight problem, can be fix?

Hello, I have a same TV with the yellow and rede vertical lines on display. Please, you can help me? I replace the T-con board, but the vertical lines is same.

That cable is LVDS cable and is you want to release from motherboard so press that 2 small pieces on both corners of lvds port.

I also have a kdl 55w650a, similar to your TV, do you know how to remove the back cover?

hello, do you still have the firmware for 55w800b please? official web site already cannot find the firmware, thanks

Thanks for the vid! Did your tv ever show you blinking red lights? Right now mines doing that. I just replaced the timing control board and after that I powered up but it’s just blinking 5 times over and over again. Before I replaced it the tv would power on and I had sound but no picture. Any ideas what’s wrong?

Great work！

I have similar problem with my board . I have changed the board for new one but the pictures are not coming . What should I do ?

I got a Sony KDL-43W800C, and it's dead like a brick without any blinks. Just wondering did your TV blink at all before the fixing?

I cant find the firmware for my KDL-55W800B?

I have this exact TV, had vertical lines. Assuming it was the T-con board ordered one from Ebay now it wont stay on and flashes red light. Maybe I got duped with a faulty T-con? If I put the old T-con in it stays on but with brown vertical lines. Any suggestions before I go ahead and order another T-con?

Would you happen to have a firmware full stock firmware file it would be greatly appreciated! Sony has removed all firmware from the website in January.. :(

i had a problem with my kdl-60nx810 sony I couldnt determine weather the tcon or the mainboard is the problem. i tried removing the cable that goes to the mainboard and the tcon still has the supply then I turned it on, then the screen turns to like color mode testing which displays color such as red green blue and gray and some shadowing. now I'm confused which one to change the mainboard or the tcon.

I swapped the motherboard on the sony 55w800c. A protective screen that switches came out. It comes green,red and blue screen..then changes to chessboard. I have the update. I have no ideia how to fix it

Hi, I have KDL-55W805A, that works very well, but shots down after 30 sec to 1 minute. I restart it, but with the same result!

Awesome vid!! I have same model TV. A storm hit. 😢 Now I got 3 blinking red LED lights. Now it won't turn on. Just keeps blinking red. Factory restore didn't work. Any ideas? ...perhaps the power board inside the TV needs replacing?

HI do you have firmware link

Great stuff. Thank you for that. I hate the fact that these things break down but are usually reasonably easy to fix. I’ve got a similar tv to yours and I’ll give it a go now!

Hi sir i have sony bravia kdl-46inch with 3 time blinking error

What are the details about the USB firmware upgrade? I have a XBR-55x700D where I replaced the PS and then Main Board and now I am at the GREEN / AMBER blinking light and no sign of life on the screen - no image, no backlight, no text. I downloaded the current FW for my set from Sony. It is a ZIP file. I extracted the ZIP to an 8GB USB stick (the FW is 1.7GB). Only the *.PKG file was on the USB stick. I put it into the set and turned the set on and let it sit for more than 30 mins and when I came back the set had turned off. When I turned it back on, I had the same GREEN / AMBER blink. I am just wondering if I am missing an details.

Hi, my sony bravia DKL-55W800B was working one day and the next nothing. No light on the screen, no light on the bottom of the tv. I checked the transformer with a voltmeter and that is fine. Next i changed the LED driver and that wasn't the issue. So I changed the Main Board and nothing. What do you think is the problem. Thank you
