Tv Philips 55PUS6031 no image, backlight ok
good night! I have this TV, with quite poor build quality. It has a tcon integrated into the panel, a single flex from the tcon to the panel, and the 2 panel controller boards joined by glued flexes. There is no way to separate them.
The symptom is that the image is not visible, but the backlight works. How to know if the problem is in the main or in the tcon-panel? I can't override zones.

I return to the matter with the second TV of this brand and model. This one has a more important problem. No image was seen. The problem was in one half of the panel. I have used the method of covering pins of one of the flexes that goes to the oanel and it has worked. However, the image is not good. It has horizontal stripes. I'm going to put images of the complete TV, and the 2 parts of the panel separately. It can be seen that the error has not yet been fully resolved. However, the image is complete. Will there be a solution?...

thank you! you were right. I ran an eraser through the flex pins and solved the problem. Now I have another same panel, with a similar problem, but after using sealing on the flexes for a panel problem. Now it is more difficult to solve because I think the problem is putting tape to remove pins....

Xiaomi L55M5-5ASP fine lines on the panel uniform
Good afternoon! Does anyone know how to remove these lines? They are very fine lines at the bottom of the panel. I have 2 identical panels, and I have even thought that this brand has this lattice format, although I highly doubt it.
The photo from the YouTube app is where it is best seen.
thanks in advance....

TD Systems K50DLG12US half black and half white screen
good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?
By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the...

hello! In the photo there are several voltage reference points AVDD, VGL, VSS. these give incorrect values. however, the 1.2v and 3.3v benchmarks are correct. The supply voltage of that integrated is correct. I don't know if the problem is with that integrated part or with another component of that circuit....1 Photo
