Re: Sony TV (kdl50r550a) issue
Thanks
After some thought, I don't feel safe using the TV for extended periods of time, especially when I'm not home and the kids are watching, so Ill replace it soon.
I'm still perplexed how people like this youtube user, had the same problem that went away, when its obviously a panel issue.

Since Ill be throwing it out soon, is there any point opening the TV any further exposing where the ribbons attach to the panel to see if anythings...

Re: Sony TV (kdl50r550a) issue
UPDATE
When using the TV as a computer monitor I can see a loss of quality in the top right corner (scan lines and the led light for that area blinking on and off).
Hard to see when watching cable unless you focus on that spot....Leave a comment:

Re: Sony TV (kdl50r550a) issue
Holly crap its fixed!
Stupid me. I was scotch taping the pins on the ribbon that leaves the motherboard to the TCON instead of the ribbon (hidden underneath a metal plate) that leaves from the TCON to the panel.
As soon as I put a small bit of tape on that the jumping stopped!
I cant even see any loss if quality.
Thanks again for all your help.
Is it OK to give you guys the credit (use your usernames) as I feel like I should help others in different forums (SONY, youtube)...Leave a comment:

Re: Sony TV (kdl50r550a) issue
Thanks for helping J
Sorry if Im confusing you.
Im 100% confident I have isolated the pin causing this issue.
The problem is, using a tiny amount of scotch tape on the spot, covering the pin so that it is 'cut off', when I power the TV on, with all ribbons connected at each end, the back light comes on, but no image (Sony icon, menus,) etc.
It just stays black.
If I remove that tape an image will appear.
I just cant get any image on the screen with the...Leave a comment:

Re: Sony TV (kdl50r550a) issue
Hi Guys. No luck so far.
When I pulled the bottom ribbon out (largest one) the back light comes on but no image (no sony icon, menu etc). When I pulled the top one out and left the bottom ribbon in I can see an image with vertical lines and the jumping scenario (shorting) I am try to fix so I imagine it is this ribbon.
There are gold contacts only on one side of the ribbon. When I scotch tape these contacts I have to use a very small piece of tape as if I use larger piece, the screen is on but again no image to work with...Leave a comment:

Question about the Tconn board and ribbon
Hi Guys
Tomorrow I am going to attamept the "cut off" method by taping the section of ribbon connected to the Tconn board to cut the power/signal that's causing the panel to short out in that area.
Can I do this with the power turnd on? IS it safe to be plugging and unplugging and adjusting the scotch tape with the power on watching the screen or should I have the power completely off each time I unplug and plug the ribbon to the Tconn.
Thanks for any help I get

Re: Sony TV (kdl50r550a) issue
When I insert the ribbon and take out etc, can I leave the TV on with the picture showing, or should I turn off the power every time I plug in and unplug the ribbon.

Re: Sony TV (kdl50r550a) issue
Thanks for helping Andrew. I haven't tried it yet.
From my understanding, I'll determine which side of the ribbon eleiminates the error by taping the whole side (I will see quality loss at this point). THen I'll gradually make the tape as small as I can untill the error comes back, then retape that spot?...Leave a comment:

Re: Sony TV (kdl50r550a) issue
Thanks so much jjanseen
This is exactly the kind of help I was looking for.
I'm going to try it today and Ill report back how it went.
I have a feeling the permanent line will be right down the bottom as that's the one I'm always seeing....Leave a comment:

Re: Sony TV (kdl50r550a) issue
Thanks for your help.
OK I wont put any hope in this TV suddenly fixing like the youtube user claims his did.
As of now, I also hate Sony. When I spoke to Sony Customer Service they told me 3 years is the expected life of a TV these days. Forget that!
The Sony Forum is more like a support group for people like me with new TVs that don't work. Such a shame.Leave a comment:

Re: Sony TV (kdl50r550a) issue
Thanks for you help.
Did you click on the two YouTube links at the bottom of my post?
Both those users (I have been in contact with them) said the issue fixed itself after a few weeks. I agree it's a panel issue but it makes no sense that it corrects itself after time....Leave a comment:

Sony TV (kdl50r550a) issue
Hi Everyone.
Hoping to get some help with this issue on this great site.
My TV is a 3 yr old Sony (KDL 50R550A). When I turn it on the whole screen moves up and down about a quarter of an inch every 3 seconds. At the beginning (when it is cold) the screen shows scan lines when it moves. It also seems to go from brighter to darker. Here is a video showing this
