Re: Sony KDL70R550A TV problem

Hi Charlie your private message basically says im out of Luck?  I did contact a sony reapir tech and he said TV is not able to be fixed, said it is unfixable.  I was told people are able to buy replacemnt TVs at a dsicount when this happens?  am i able to do this or do I have to put my 2300-dollar SONY tv in the dumbster, and instead of getting another SONY buy a walmart VIZO for 1/3 the price...  Sony is supposed to me premium brand but i can not see myself buying one again if it only last 3 years.  I paid 750 dollars a year i guess to lease this tv

Adam, if you have been following this and other related threads you will see that Sony is treating EVERYONE with disrespect on this model of TV. Moderators jump in on every new poster and send a canned "Sony-speak" response. The very least Sony should do is provide a credit solution that covers a minimum of 80% of the original cost of TV, adjusted for inflation, of course. Given that prices are coming down all the time that would allow us to replace our sets with something comparable today. I might even cow-toe and buy another Sony... maybe... if they compensated me fairly.

Re: Sony KDL70R550A TV problem

They aren't doing anything, all the people on this thread aren't able to get a class action suit going, and everyone has lost their money. ****** it up and buy a 4k Samsung or something like I did. Looks better, it's bigger, thinner, native hdr, Sony makes garbage and hires garbage. The end. There is no luck when referring to customer service.

Re: Sony KDL70R550A TV problem

I just wanted to say that I also have a KDL-70R550A with the good old red led blinking 5 times.

 

BUT for now it is fixed and working again!

 

 

I tried the suggestion by @budwich on the badcaps.net site.
I don't think urls are allowed to be pasted here, so I suggest going to the badcaps site and doing a search for "LC-70LE550U".
In the search results click on the thread "SHARP LC-70LE550U - side driver issue?"

 

I read the thread and to be honest it sounded fake and like it would not work. However I was going to chuck out the TV anyway so what did I have to lose?

 

I did the following steps. Take caution when back is off tv and it is open and plugged in! Do not touch anything when it is plugged in! Do not remove any ribbon cables etc while it is plugged in, always turn it off first.

 

I removed the black plastic back of the tv, then the black plastic bezel around the front. I had to disconnect the speakers and little indicator panel from the bottom of the bezel before I could remove the bezel. Next I removed the metal covering from each side of the tv. Now I was able to easily access the ribbon cables that connect to the bottom of the screen on each side.

 

I disconnected just the right side ribbon cable then plugged the tv in, the led blinked red and I was not able to turn the tv on when I pressed the power button on the remote. So I reconnected the right side ribbon and disconnected the left side ribbon cable. I plugged in the tv and it still blinked red, but when I pressed power on the remote it turned on. The left side of the tv was not lit up correctly, it was like the backlight was no on for it. I turned off the tv with the remote and then it just showed a steady red led like normal when the tv is off. So at this point the failure status is no longer in effect. I unplugged the tv and reconnected the left ribbon cable and replugged the tv and I again got the blinking red led and tv would not turn on.

 

So now I knew that for me the left side was bad. I unplugged the tv again and removed all five "tabs" from the left side of my tv. They are like stickers. I first peeled each "sticker" off the lcd panel, then I peeled each sticker off the green circuit board. I gave the circuit board a clean with cleaning alcohol to remove any stickiness left behind. This may not be needed.

 

I then plugged the tv back in (with both bottom ribbon cables connected) and pressed power on the remote. It booted up fine with the screen looking normal and no backlight issues!!!


I have only just done this about 30 minutes ago, so I don't know how long this "fix" will last. But I have now gone from a useless brick I was about to throw out to something that appears to work fine. I don't know if it will work for you, but if you are about to throw it out anyway perhaps its' worth a try Smiley Very Happy

 

I will report back in the future if I notice any issues or if it stops working again.

 

Oh one thing to note, I removed the tiny indicator panel from the bottom of the plastic bezel and reattached it to the ribbon cable coming from the tv. This is required because this tiny panel has the status LED as well as the infrared receiver required to receive signals from the remote.

Re: Sony KDL70R550A TV problem

Oh and if u connect indicator panel and have it behind the tv like I did, you will need to point your remote behind the tv at it for the remote to work.
