    Sony KDL-46Z4100 distorted image with green vertical lines

    Hi Folks -

    After 6 years this TV is giving me problems.

    Symptoms: after some period of use (could be minutes or hours) TV gets vertical lines, distortion, and a green cast. Power cycling it will fix the problem.

    Image and video below.

    I haven't cracked open the case yet. From reading other posts, it looks like the T-CON might be the problem. Any insight or suggestions?

    Thanks.

    try re-seating tcon connector and maybe the ribbons into the tcon, could be a bad tcon, check this video for how to. https://www.youtube.com/watch?v=rNNhghZ1pkA

      Thanks for the video link.

      TV is now totally dead. On power-up the standby light flashes 14 times.

      I tried reseating the connections to the t-con board. No luck.

      Based on another thread I read, I disconnected the t-con board and tried powering up. Back to green LED and backlight.

      Here are images of the labels and boards. I'm having a hard time finding a replacement board for sale.

      Can anyone tell me which number is the best part number and/or where I could buy one?

        Hello,

        There is a guy that has a repair service for these boards in eBay. Probably your best bet to get the tv back running.

          did you try a firmware update?, might not be the problem but you never know. http://esupport.sony.com/US/perl/swu...00&upd_id=5351

            look the tcon over real good, if you find anything labeled F, F=fuse, test it with multimeter.

              spotted a fuse here, F601, test it for expected 24v, http://assets.shopjimmy.com/media/ca...253-11-TOP.jpg

                those tcons seem pretty popular, so I wouldnt doubt thats your problem.

                  Actually I wouldn't be surprised is that was your problem. I've been spending a lot of time at this board now for various different failures from blown F 603 to slow refresh images to perfect working one minute to fading away locked up image that go us to vertical bars and noise on the screen. All tcon problems and not a panel issue. Still trying. Got 3 of these boards to repair to go into 3 good tvs. I can tell you if F 603 goes open you will get a blank picture upon startup and then 14 flashes. I've replaced all known component failures like the 4 diodes and ics that rrunt he voltage regulators and the voltage regulators themselves and doesn't solve any of the issues.
                  Did I leave the soldering iron on?

                    came across this repair kit, requires soldering, http://www.ebay.com/itm/SONY-T-con-R...-/141478161382 the little buggers don't show us the individual parts, just says 8 components.

                        these guys may have a repair kit or can put one together, I usually shoot the seller a question, like do you have a repair kit for whatever model. http://www.ebay.com/itm/SONY-SHARP-V...item1e95a7c20d

                          repair service for 45 plus 10 shipping, you have to send them your board, it says for a kdl-40z4100, you could ask them if they can do yours, they appear to be an electronics repair shop.

                              couldnt seem to copy paste the url, anyway the ebay seller is masessum, if you put that in ebay search, the store will come up.

                                ok, I havent tried them, maybe some of these so called kit sellers are less than honest.

                                  I'm thinking theres a definite problem with these particular tcons, very seldom do I see the tcons costing way more than the main and power boards, like these seem to.

                                    Thanks for all the help.

                                    The link to Tri State Module is the right part but if you click to actually try to buy it, then it says out of stock.

                                    I've got enquiries out to ebay seller masessum and to Coppell TV Repair to see if they can do it.

                                    The part number on my board is different than what all the repair places have listed -- 55.46T03.C03 vs 55.46T02.C02.

                                      Sony TCon on AUO panel?? Strange.. The symphtom seems very similar (solarization) to many AUO panels with AS15 faulty, here the gamma chip i don't know where is, maybe IC400 maybe IC901-IC902 but anyway the technique for soldering those become very inaccessible, i saw some video on youtube on how to do this but seems pretty near a sorcery.

                                          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...

                                          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

                                          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...

                                          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...
