Hi, TV boots with distorted image right side mirrored verticaly sometimes vertical stripes making off-on turns picture to normal and "perfect" (netflix image) that I highly doubt this is something related with t-con signal lines?? rather it looks software corruption bad mem chips voltage collapse or an intantaneous fault with fluctuating powerboard voltages?? As it happens usually when TV is cold sometimes fault comes back after a full day use should I check powerboard voltages with oscilloscope??

you could start to inspect the down side of the PSU... all area which had burn ( black on the top ) resolder the area... also take out the LVDS between the MB and TCON to clean the contact pins and seated back again -

Hey everyone,
I bought a MacBook A1990 with no screen. I bought it knowing the motherboard was defective but wasn't sure what the problem was until I received it. It actually turns on but as you see from the attachment, it has vertical stripes, on an external screen!!
The board is neat. Not opened before for sure. Just a little dust, nothing more.
Recovery using wifi can be opened, as can also be seen in the photo but it doesn't go all the way through after connecting it to a wifi. It downloads the initial Recovery files but never completes the rest of the... -
good night! I pass photos of this tv with vertical stripes. what problem could it be? panel or tcon? the tcon of this model is integrated into the panel. Let's see if they can tell me what to do to see if it can be fixed. the vertical stripes have a certain pattern, because there are some equidistant.... -
Hi, I have an Asus VX24AH monitor that suddenly went black and didn't display a logo when I switched it on. After extensive research (also thanks to this forum) I was able to get it to show a picture by disconnecting the STV (VSTB1). Unfortunately, the right side now shows horizontal stripes and it looks like every 2nd pixel row is missing.
Can anyone help me with this? Can it still be saved? I would also appreciate links and references to literature or other information.
Before disconnecting, the test point of VSTA1 and VSTB1 only measured 30 ohms. I therefore disconnected...08-26-2024, 06:45 AM -

Hi all,
I have Hisense H55U7B TV with no picture, only big vertical stripes. I did several tests and I'm not sure, where is problem.
1. Connected tcon to 12V, white, red, green, blue, black picture visible in cycle on full LCD without error
2. Connected only left side of LCD to tcon, big stripes
3. Connected only right side of tcon, visible normal picture on the right. Working as expected.
Where could be problem?
Tcon RSAG7.820.7932/ROH
Main board RSAG7.820.8698/ROH
