Simple question, am I correct in assuming that a properly working TCON will show the 12V feed through the SMD fuse?
Thanks!
Thanks!

Re: Measuring TCON Voltage through fuse
Your looking for around 12 volts on each side of fuse black - probe on metal chassis back red probe on each side, that way you know that you have 12 going in and 12 going out and that your fuse is good. -
Re: Measuring TCON Voltage through fuse
So you have 12 volts on each side of fuse? It would be going into tcon from mainboard not power supply.Last edited by nomoresonys; 08-01-2020, 09:19 AM.Comment

Re: Measuring TCON Voltage through fuse
No, I have 4.8 mV on both sides of the fuse. The TCON_VCC12V line that runs from the PSU to the TCON has 12 V on all terminals. Those lines feed into the connector that is the right of the LVDS ribbons.

Re: Measuring TCON Voltage through fuse
Ok, was a guess, since there was no model and no pics. Do you have 12 v coming out of the connector? tcon fuse is good? has continuity?Last edited by nomoresonys; 08-01-2020, 10:32 AM.Comment

Re: Measuring TCON Voltage through fuse
Test CN6401, test number 3 below, there's a label there see it, list the pin number, name, and voltage both in standby/tv plugged in but off and when you hit the power on, video 2 is a demo of testing.Last edited by nomoresonys; 08-01-2020, 10:44 AM.Comment

Re: Measuring TCON Voltage through fuse
If you have 12 volts on pins 3,4,5 of the white connector, you should have it on that end of the fuse, If not, either the pins of the plug are not making contact with the trace or the trace between the pins and the fuse is open.Attached FilesComment

Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side... -
My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
Then I get an idea to take it apart and clean boards from dust.
In side of Tv was not so bad, I take compressed air in can, and gently blow up.
Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher... -
I could have sworn I posted about this before, but I can't seem to find the post..
To whit..
I have a 60LN5400 that came in.. Backlights work fine.. No display..
Traced the problem to the TCON board.. Blown fuse..
Replaced the fuse.. Blows again.. Replaced the fuse again... This time it fries the marked part on the Main Video board...
Got a new Main Video Board.. Replaced the fuse on the TCON..
The fuse is fine and the backlights come on fine if I don't have the cellophane connectors from the TCON to the... -
This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
Hi Everyone, I am new to this forum. I have a Panasonic LED TV which doesnt turn on and is blinking 4 times repeatedly when I turn on the switch. The TV does not respond to the remote control so I had to turn on using the physical switch on the side of the TV. When I turn on the switch the 4 x blinking starts and repeat itself until I turn off the TV. There is a black screen. I turned off the light in the room to check the panel and I think there is no backlight as far as I can tell.
I have been inspecting and testing the capacitors and diodes in the power supply board to try to...
