Hello, on my samsung tv I have 2 packs of ckv1, ckv2...ckv8 on the driver panel. On the left side I have about 1.7 mega ohms between ckvs but on the right side I have 1.7 mega ohms between ckv5, ckv6, ckv7, ckv8 but OL with ckv1, ckv2, ckv3 and ckv4. What can I do please ?
@@tevzTVTevatronics Samsung TV model is UE70TU7175U. Initially, the television rebooted and flashed red twice without the startup sound. I disconnected the cable between the mainboard and the power board, the backlight worked fine and the TV no longer rebooted. Then, I reconnected this cable and disconnected the ribbon (I only have one) between the mainboard and the panel. I still had the backlight and heard the startup sound so I thought it was a panel or panel driver problem. I have 2 ribbons on the panel driver so I unplugged one and the TV started up fine with sound and backlight. I tried unplugging the other one and the same thing I had sound and backlight. I reconnected the 2 ribbons and I now have sound and backlight even though this was not the case initially! Very strange. I don't measure any voltage on the panel driver and I measure voltages on the mainboard coils like 12.9v, 3.3v, 1.8v but 2 coils have no voltage. I didn't find a short circuit on capacitor and I don't see a fuse between the mainboard and the driver. I'm lost, I thought it was a panel problem but not sure at the end...thank you for any help
@@tevzTVTevatronics Samsung TV model is UE70TU7175U. To make a long story short, yesterday it rebooted and flashed red twice. I disconnected the cables and ribbons to isolate the problem. I thought it was coming from the panel but after reconnecting everything I no longer have the same symptoms, everything seems to work but I have no image and I does not measure any voltage on the panel driver. I also don't see a fuse between the mainboard and the driver. I find voltages on the mainboard coils 12.9v, 3.3v, 1.8v and 0.44v (strange). Maybe a dc to dc converter problem? Thank you for any help 👍
@@olivierj.2435 Some Samsung if you disconnect one of the cables dont actually work. it does not boot at normal, try isolating the cables with tape or paper between the contacts if you can identify the ckv lines.
@@tevzTVTevatronics Thank you but near the ribbon between mainboard and panel driver I have 4 coils and I measure 0.44v on it whatever ribbon is connected or not. Do you think it could be à DC to DC converter problem on main board ?
Hello Tevz thanks so much for your great work. We do really appreciate your relentless effort in teaching people like us . May GOD continue to inspire you with good visions .Please I need your help this scalar t-con PT320T02--1-XC-1 has a double image could you indicate the ckv1&2 and ckvb1&2 for me is this GIP or non GIP tnx GOD bless you
Hi dear Mr tevz. I have heard the word vone by you for the first time which seems is the same vgh at 30 volts. But I did not get that you mean we can disconnect all skv1 or just connect them all and to the gnd! Is that right or I am wrong?! Glad to have us Thanks o lot.
@@tevzTVTevatronics so one side open and not getting clk signals. The other side partial short and not getting clk signals. I think GOD is making this TV work .hehe
good morning sir , ask ko lng sir, ung monitor ko no input display or cable disconnect na labas sa screen , ano kaya problem , parang ganyan ang problem, tnx much

You must have spent many hours and tried many different methods for panel repair. Must have been by trial and error as no real clear info on the net for each of the many types of panels and circuitry. Would be good to do a video on the finer details.

OL doesn't matter. Seems you dont tell me what is the problem.

I think it's a GIP, try disconnecting the ckv.
Sir watching, from isabela.City.Basilan province. Would you mind what is the brand of your clamp tester and model? Thanks
I dont use a clamp meter on this video.

But I did not get that you mean we can disconnect all skv1 or just connect them all and to the gnd!
Is that right or I am wrong?!

Thanks o lot.
The ckv that been cut is solder all to the ground, but not all will work, live it hang instead.
Do you see a light difference between the two sides. Maybe 326 ohms one side and 324 ohms other side?
the other side is open
@@tevzTVTevatronics so one side open and not getting clk signals. The other side partial short and not getting clk signals. I think GOD is making this TV work .hehe
@@Swenser The open side is the one that is working, the 326 ohms is partially shorted which is faulty.
@@tevzTVTevatronics sorry I thought you meant burned completely open.
Thanks sir how do you know the pinout
indicated on the right area of the board.
Bro . Please start a Course Video series from basic
Hello, engineer, if your monitor turns off at a certain time, for example, 30 seconds, what is the problem
Try replacing all the electrolytic capacitors. Could also be heat related bad solder joint. So you can diagnose that with heat gun and freeze spray.
good morning sir , ask ko lng sir, ung monitor ko no input display or cable disconnect na labas sa screen , ano kaya problem , parang ganyan ang problem, tnx much
Baka ung CPU mo ang sira.

Why these cut not brake the image ?
These lines goes two side of panel
