Re: Double image, Blur and Whitening on Grundig LCD 32
Try turning down the backlights NOT brightness, see if the double image gets better. -
Re: Double image, Blur and Whitening on Grundig LCD 32
Try cooling the COF, doubled images due to Gate drive failure.
BTW, picture #1 with bunch of black diamond patterns, do they go away and changed to double images?Attached FilesLast edited by budm; 02-25-2019, 09:59 PM.Never stop learning

Re: Double image, Blur and Whitening on Grundig LCD 32
Might be able to get a good picture with the "cut tape" method, many threads here and on youtube for the procedure.Comment

Re: Double image, Blur and Whitening on Grundig LCD 32
I wouldn't pay 40 for a 32 inch tv in this condition, more than likely it's cof as mentioned which is considered un-fixable without very expensive equipment. The cut tape etc. methods sometimes work for certain conditions but how long they will last is always the question. It's one thing to try fixing your tv that you already own but to pay for one with this type fault, nah, plus I never heard of a grundig tv, PASS.Last edited by nomoresonys; 02-27-2019, 09:15 AM.Comment

LCD displays a 2nd image slighty offset vertically. And multiple pairs of black lines along the bottom. Probably common as google "TCL 49S405 double image" pulls up this ifixit post ( link ) with identical ( nearly, but their fault seems to be on the other half of the panel than mine ) problem without solution.
This one looks to be a more difficult to diagnose because most? of TCON seems integrated ( CSOT BGA on buffer baord) into the left panel edge board ( looking from rear of TV) There are 2 buffer boards for each 1/2 of the screen. Main connects to the left buffer board... -
Hello team,
I'm back with another tv and another problem.
I try to improve my knowledge on fixing TV, and all technics used until now are not fixing correctly the problem.
First, reboot issue, I use tape Method to find out the right side that cases the issue.
Then using this it's working for quite 1hour30, then at some point of time the image became double on the bottom for half the screen.
Then double image reduce in height and move to the top.
The image is like folded on around 1cm and the bottom has been moved to the top by 1cm.

My 2001 Toshiba 50WP16 50" plasma TV has, after 20 years of trouble-free service, developed a wierd fault in the last 14 days during normal viewing - with no loud bang or smoke or any other excitement.
Every 15-30 secs the right hand half of the image has a "glitch" for about 1 second before reverting to normal. The glitch has two forms and also depends on the aspect ratio setting (see photos):- 16:9 either a) a visible seam between LHS and RHS of impage or b) LHS image duplicated on RHS (photos 16x9)
- 4x3 either a) no image on RHS or b) RHS image offset by 1/6th

Hi there,
I think it might be a bad panel but I thought I'd ask before I chuck it..
thin colored horizontal lines bottom and thin section on top. As it runs warmer, you can see some ghosting or double image. Right hand side of the screen darker then brighter (backlight is always on, so it's the actual LCD that gets darker and brighter)
Replaced the Main board, because I had one handy, no change.
Is it worth replacing TCON? disconnecting ribbon on one side of the panel, the lines appear still on the other side (unplugged side.)
