    Technika LCD37-909

    Any advise. Got a Technika LCD37-909 which does not display a picture for about the first 5-10 minutes its switched on. After that it works great but occasionally 2/3rds of the picture goes then comes back.
    Looks like something needs time to heat up. Any ideas ?

              Hair dryer and a can of air upside down can be your friend here.
              From cold you can turn tv on and blast hot air on a board to see if you can speed up your warm up time.
              Once you found which board reacts to the heat you can then concentrate on that board.
              Take the can of air,hold it upside down and spray the freon on parts of that board to see if you get a reaction,great way to "zoom" in at the problem area.

                Hi tom
                Do you know please the service code for UHc tvs please ?
                It's a 19 inch LCD DVD combi badged technika model number m19n11n02g 801 or lcd19dvdid307 but I think it's got UHc boards and not vestel as none of their codes seem to work.however the umc code 9735 to hack the DVD works
                I want to start the first set up installation as there is no option in the normal menu to do this.Problem is it does not allow tuning in digital mode ( aerial symbol is greyed out ) ,analogue is ok
                Be really grateful if you know !
                Cheers Pete

                    Hi
                    Thanks for the link
                    I've tried those codes mentioned but none work!
                    I think because the code 9735 ( a unc code I think ) works as a hack to change regions for the DVD I gather it's a unc code I need rather than vestel
                    Anybody out there know what the unc service codes are please ?
                    Cheers Pete

                        Re: Technika LCD37-909

                        Sorted !
                        Thanks to everyone for there help
                        Cure is to use a one for all remote
                        I used the Urc 6440 which is a good one to have as it is upgrade able
                        Use one for all code 2426
                        On this particular remote the key marked text becomes the digital tv menu !
                        There you can do a first time install to find any new digital channels
                        Cheers Pete

                          cool glad you manged to sort it thanks for posting the fix but i guess if you have a original remote control which has the digital tv button you wouldnt have this issue?.

                              T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
                              by Tr0ll
                              Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                              The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                              Original T-con:
                              Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                              First replacement T-con:

                              I thought it might be t-con and ordered new t-con from china(supposedly tested)...

                              SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
                              by JJAAMM
                              This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                              Problem
                              TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                              Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
                              by TR103
                              Hi, I have a Samsung UE50TU with:
                              - sound and backlight, but no picture
                              - when it arrived, it had a picture for a few seconds
                              - it keeps rebooting
                              - without ribbon cable between the two panel boards, it does not reboot but I have no picture
                              - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
                              - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

                              - without cable between mainboard and lcd panel and with a jumpered...

                              Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                              by Mgiffune
                              I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                              I ordered a supposedly ‘new' Tcon board this time, and
                              ...

                              Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,...
