Anyone know how to initiate IN-STOP on this TV? Wanted to restore all factory defaults before I make any further progression on this TV. I've done the audio file method but only was able to initiate EZ-ADJ and IN-START.

Re: LG 55LW5600 Solarized Picture T-Con Board?
Before doing anything like that I think you should open this puppy up and take some voltage measurements on the T-CON Bd. they are the Vgma voltages. -

After measuring voltages I powered up the TV and now there's just vertical lines all across the panel.Comment

Re: LG 55LW5600 Solarized Picture T-Con Board?
Did you short out any thing? All the cables back in correctly? I think those readings are good, though. Anybody wants to concur on this?Comment

They don't look right to me, but give me a minute and i'll stick them in that spreadsheet to confirm.Attached FilesLast edited by diif; 07-27-2018, 02:39 PM.Comment

Re: LG 55LW5600 Solarized Picture T-Con Board?
Here's a picture of the lines present on the display. T-con board still shows the same voltages as what were previously measured. Didn't slip with my probes or see sparks/smoke. Stumped on how this has happened.

Re: LG 55LW5600 Solarized Picture T-Con Board?
I re-seated all the video ribbon cables lines still present. Absolutely no picture is displaying. I was extremely careful measuring the voltages. Never know though I could have caused a short somehow. Since the problem is now worse than it was it had to be my touch. lolComment

At least no you know you HAVE to get that new T-CON Bd, now....

Re: LG 55LW5600 Solarized Picture T-Con Board?
I'm thinking my panel is shot. I do have a cracked panel from another 55LW5600 I parted out would it be wise for me to see if that panel displays the lines as well? There was enough picture on the right side of the screen that I believe it can help me rule out if the panel is messed up.Comment

Re: LG 55LW5600 Solarized Picture T-Con Board?
That other panel wasn't stored in a safe place and has no picture at all now. Guess I'll order the t-con board and cross my fingers.
Thank you for the Help Andrew and Diif! Will post back when I get the t-con board replaced! Also have another TV with power supply issue. Will post a new thread for that one.Comment

Yes. Please do appraise us when you get the new T-CON Bd. Good luck.Comment

Re: LG 55LW5600 Solarized Picture T-Con Board?
Did you try disconnecting one side of the panel at a time ?Comment

Re: LG 55LW5600 Solarized Picture T-Con Board?
I tried that. Just got the new t-con board and the lines are still present.Comment

Re: LG 55LW5600 Solarized Picture T-Con Board?
I get nothing with either side disconnected.Comment

Re: LG 55LW5600 Solarized Picture T-Con Board?
are you saying you still get the vertical lines on the side that is disconnected??????Comment

Re: LG 55LW5600 Solarized Picture T-Con Board?
It's a bit of a complexity I seem to get different results with only one ribbon cable in. Sometimes right side of screen is white, sometimes the entire screen is just dark. Sometimes there's lines but they are very faded. There's no picture at all though.
Edit: I didn't notice at first but with only the right side connected the left side of screen is a bit brighter than the right side.Last edited by tvfixer007; 08-01-2018, 02:42 PM.Comment

Re: LG 55LW5600 Solarized Picture T-Con Board?
well that's quite a bit different than "I get nothing with either side disconnected." You would be wise to post some pictures of what you are actually seeing with various cable disconnect scenarios to remove any "misunderstanding". Ensure that you are feeding a good signal along with also trying different menu screens to see show as much about what is happening on the screen. My guess would be an SMD capacitor on the bottom edge board might be bad.... but that's going on very little. Where did you get your tcon from? what's history on the set that caused the first post (ie. solarization).Last edited by budwich; 08-01-2018, 03:01 PM.Comment

Hi,
I have a VIZIO E70-E3.
Symptoms: Black screen, no picture, but LED backlights are working.
I probed the power board and voltages are as listed on the board.
Main board appears fine, too.
I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
There are two separate ribbon cables feeding the LCD.
If both are connected, the screen is black.
If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and... -
hi
i have a samsung lcd tv
it powers on with sound and backlight but no picture
all voltages from PS are good 12v 3.3v and 5v
whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v
i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue
no 12v at the tcon fuse
i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse
the odds of having 2... -
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... -
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)... -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
