Re: sharp lc-70c6500u half picture
probably would have been wise to post BEFORE you removed the side tabs. :-( maybe check the components on the bottom edge board for the bad side for shorts or otherwise. Doesn't look good. Double check your cable seating at both ends. -
Re: sharp lc-70c6500u half picture
What was original symptoms, was the display picture the same as it is now before the tab removal?Comment

Like the title says , this is a very interesting problem , never experienced this before so i thought i'd share and maybe get some help on this. So the problem is as such: TV comes on , some gibberish flashes on screen and the screen remains black , the owner of tv said he heard sound. Now i checked some things cleaned all connections first of all so i dont run in a circle. Then i disconnected one of the cables for the panel , and viola, the left side of screen comes on, then i tried to switch it , with left side disconnected and right connected. Same problem persists. I checked some voltages... -
I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display... -
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)... -
TV was fixed just after removing Samsung's rear snap cover.
This curved TV's construction is rather interesting. When the snapped on back is removed, rest of the TV will relax the curvature. Top of LCD panel is loose as it wants to straighten out against the slightly curved bezel. Snapped back provide most of the curvature shape. So just simple disassembly of rear cover will allow the rest of the TV frame to relax its curvature. Thats probably what fixed it but no idea which connection. 4x LEDs are edge lit.
Maybe PSU->backlight connector didn't have a good contact?...07-23-2025, 12:34 AM -
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...
