    Re: Sony KDL-46Z4100 distorted image with green vertical lines

    Hello folks...don't post here much, but have found some good tips over time so I reckon I'll contribute...I looked at the image from the Sony BT2 board, usually the regulators on the board short out, & no picture appears. If you have a voltmeter, check the voltages just to the left of the "BT2" stamped on the board...the top should be 3.3v & the bottom, (Cayenne-T) 1.0v. The other two about 1.9v I believe. Don't run the board long without heat shield in place or else....

        Conclusion (in case anyone is still following this thread):
        • I was not able to find any T-CON boards of this model for sale.
        • I was not able to find anyone online who was interested in repairing this model of board.
        • My soldering skills are not good enough to try it myself
        • I took it to a local shop and they offered to "rebuild" the T-CON for $195 and offered a 60 day warranty.


        Since I can get a new TV with equivalent specs for about $500 this will be the end of the line for this Sony. Now just to decide what to buy to replace it...

                Flyfish it don't seem the same issue as the O.P. so please open a new thread..
                cope360 have you trashed the tv? I don't think 195$ is so high price instead of 500$, i really don't understand your point of view... :-(
                i have repaired an expensive tcon on some Sharp panels, the faulty part was a mosfet, here there are 8 in a row, my first watch is to them..

                    Samsung LA46A950 aka. LN46A950 - intermittent vertical green lines / distortions
                    by 265chemic
                    Hi All,

                    I have a Samsung LA46A950 that intermittently was displaying issues with evenly spaced vertical green lines only on dark / black areas - this has progressed to more often and blue lines sometimes, as well as a little image distortion.

                    My initial suspicion was the T-CON board, which I took out and cleaned but the issue persists. A heat gun on all of the control boards makes no noticeable change. Ive also reseated the T-CON to panel ribbons (4 of them) and moving them while the panel is on doesn't seem to change the issue.

                    Below are some photos...

                    Sony KDL-40V3000 - Vertical lines
                    by gpo23
                    Hello,

                    i order a t-con because i had bad colors on my SONY KDL-40V3000 :




                    With the new t-con the color are good but there are vertical lines on all the screen :




                    I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)

                    Is there a way to fix the vertical lines on the new t-con ?

                    Thank you for your help

                    Samsung P2770H vertical green lines
                    by wkx
                    I have a Samsung P2770H monitor, on which I replaced the main board because it has an issue that it would restart itself every X minutes, that resolved that issue.

                    Now, a few months later I turn the pc on and find 3 1px vertical green lines on the monitor, the lines wont show up on a screenshot. Does the same with dvi or hdmi.

                    I opened it up and made sure the panel connection to the board wasn't loose and the flat cable looks ok. Pressing the connectors while the monitor is on sometimes changes the line colors from green to blue or yellow, but the lines are always...

                    1/3rd of screen black with occasional vertical lines - repair attempt for learning! - Kogan KALED58RT9220SVA
                    by Firentiosi
                    Thanks for offering your assistance with this. I'm an electronics enthusiast with moderate level of competence (have a decent lab with two power supplies, microscope, DSO, hot air, good iron, can competently work at a component level on SMDs, design and solder own PCBs etc). I really enjoying fixing things and learning new stuff so took up a free 58" LED TV and have been googling and watching Youtube videos to see if I can fix this! I am happy to go down to individual component replacement/strip replacement etc - it's all in the name of learning.

                    The issues are as follows: the...
