Hello,i have Samsung LE46A756R1M lcd tv,which developed a tab bond issue,i stripped tv down and isolated offending tab top left,put a shim between frame and all was good for two weeks,but it went again i found a repair centre to fix tab bond permanently,to cut a long story short,when i was at the tab top left,i hit the little resistor types on the source drivers board attached to tab,with my ring,and picture faded away,still have sound,what im hoping someone with knowledge can tell me what the knock on effect of shorting the drivers,when i disconnect the side that i shorted i get half white screen,what i need to know have i destroyed the panel or would the knock on effect destroy hopefully the t-con,sorry if is hard to understand if any more info is required please don't hesitate to ask,thanks to anyone who replies.

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... -
The TV shows a black screen with no image.
TCON ribbon connectors were disconnected individually for image and there was no half image even.
Later both ribbons were disconnected and TCON voltages were tested.
12V, 3.3V, 1.8V were seen present but VONE signal reads 0V.
There is also a short to ground in this circled inductor.
Is this a TCON issue or something else ?... -
I have an Arcelik TV with BOE HV650QUB-F70 TCON board, but I think there's an issue with/around PMIC.
PMIC: iML8940
There is backlight and sound, but no picture. I watched a YouTube video and turned it off, half an hour later it was dead.
Input 12v, fuse ok
DVDD1V2 = 1.2v
DVDD1V8 = 1.8v
DVDD3V3 = 3.3v
VGL = -7v
**VGH = -0.3v
**VCOM0, AVDD, HAVDD = 0v
SWBK1 = 3.3v
SW1 = 12v
VGH to GND resistance is 500kohm as expected
Readings are same after I disconnected the two cables from TCON to panel... -
Got this TV free. Guy said it tries to turn on and doesn't. I haven't seen this specific issue before but shown in video. Any way to test the screen to rule it out on these Vizio? Or anyone seen this issue before?
Any help appreciated

Good day, I have a TCL TV: Model 43s423. After turning ON the TV, the ROKU TV logo appears with fine lines over the whole screen, then after a while there are vertical bands in the middle of the screen top to bottom and the TV tries to update its firmware but I do not have the remote to connect it to my new network connection. Also the Power ON light blinks 2 times in quick succession. When I remove the ribbon on the right of the tcon board the left side of the screen shows but with fine lines. If I remove the left side ribbon and connect the right side ribbon the whole screen is blank with...
