I have Samsung un60es6100, it would turn on had sound no picture just backlights on. I replaced tcon and all I get is vertical Bars shown in picture . Is the panel just gone bad?

Re: SAMSUNG un60es6100 bad panel?
There is a good chance it is. Try removing one ribbon at a time from the T-con and see if half of the picture returns.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: SAMSUNG un60es6100 bad panel?
I did try remove one side at a time . Just white on that side no visible picture on the other side the bars do change and no picturesComment

I would say about 90% chance it is a bad panel.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Do all the tabs fail at once or is it the boards that drive the tab Bond that fail.Comment

Re: SAMSUNG un60es6100 bad panel?
hard to tell by your picture, but are the "vertical linings" happening on both "halves" of the screen? If not, then something isn't right that you have no picture when the bad half is disconnected. Otherwise, if on both sides, likely its a panel BUT it could be a "washing event"... :-) check the bottom edge boards for "water damage".Comment

Re: SAMSUNG un60es6100 bad panel?
Basically an LCD panel is driven from the top, array of source drivers, which send each line of video to the screen. You probably do not know how an LCD pixel works but it is a lot like a transistor which has a drain, source and gate. The drain is one end of the actual liquid crystal cell. (The other end connects to a common voltage, something called VCOM.)
The gate drivers which run along the left and/or right of the screen select the appropriate line to "write" data to.
So you can think that for each line of video data on the screen, if the gate driver signals are incorrect, then the same data will be written to each line. This is what you are seeing, essentially all pixels are getting all data written to them, the line select is not working.
To get the signals to the line select driver ICs (gate ICs), the signals are often, though not always, passed through the source driver ICs which run along the top of the panel. So most likely it is:
- Connectivity issue between the source driver and the gate driver ICs, so the gate drivers do not select the right line
- Connectivity issue between the source driver and panel board, so the source driver cannot forward the data
- Issue with the T-con, such as an output issue or programming failure (rare, but the only truly fixable issue)
- Short on a gate driver IC causing addressing issues
- Fault on first gate driver IC in the panel causing all subsequent addressing to fail (there are usually 4-8 gate drivers depending on the resolution of the screen)
Too long, didn't read? Panel's probably fucked. But there's a small chance it can be fixed, budwich may be able to advise if the Sharp hack applies here.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Well said Tom!Did I leave the soldering iron on?Comment

Re: SAMSUNG un60es6100 bad panel?
Thanks for the info.
This is tcon they sent me BN41-01947A if I got wrong tcon would it cause this issue? I have had bad panels before but disconnecting one side or other get some sort of pictureComment

Re: SAMSUNG un60es6100 bad panel?
Should be a BN95-00708C. Do you see this number on any of the tags on the board? Apparently this panel is manufactured by sharpDid I leave the soldering iron on?Comment

Re: SAMSUNG un60es6100 bad panel?
The board they gave you is for a un60f6300 or 6350 series tv. One year newer Unless they know something I don't it sounds like it's completely the wrong board. Even though it appears that both of these boards operate a Sharp LCD panel they may have different output drive signalsDid I leave the soldering iron on?Comment

Re: SAMSUNG un60es6100 bad panel?
On shop Jimmy the board I got says it can be used as a substitute but in the description says the board's been modified to be a substitute for the board I need. I didn't get my board from shopjimmy so I wonder what modifications they do that it can be a substituteComment

Why don't yo try repair the old tcon? Maybe post an hi-res sun-light picture..Comment

- Prior owner tried a replacement main board. No difference.
- Samsung 2x red blinking standby LED = panel fault
- Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
- Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
- Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.
There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

Well, I will be the first to admit that I screwed up...
In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.
I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.
I have 2 that I have found and have in my possession. ... -
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...
