Just picked this 20" LCD from the dump and plugged it in. Obvious right away why it was relinquished to the landfill. OSD comes on, but several vertical sections of the display flicker on/off. Looks like the display is divided up into six equal vertical segments. The three on the left are always on. The three on the right come and go as the t-con/LVDS (?) boards are pressed. Seems like the flat ribbon cables are delaminating? Never worked with the flat cables that connect the t-con to the LCD. Is this a fixable problem, or a waste of time?

Re: Sylvania LC200SL8 - vertical stripes
I am guessing panel failure. These TVs have all the T-con logic (whatever is left of it) on the main board.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

by Daren87Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
by ahoonidHey 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... -
by kevinmanHi, 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??4 Photos

by halenHi 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?

by advantThis thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... - Loading...
