Do you suppose replacing the TCON F101 would provide the same results? I do have a donor board and i'm much more confident swapping ICs than injecting voltage.

Here are my results after trying 'Iotas' suggested fix. It was in fact a signal timing issue. Effectively this Television has been saved from E-waste so I'm satisfied with this conclusion. There are vague lines when the device first powers on but it's hardly noticeable with...

Thanks! I’ll give this a try tomorrow....

Having trouble identifying the CKV Line without a data sheet for the IC. My search yielded no results. Is the CKY marked differently on this T-CON Board?

I double checked pin connectors and ribbon cables and everything is intact.

Disconnecting the left bar from the T-CON allowed the opposite side of the screen to display correctly.

Disconnecting the right bar from the T-CON resulted in the same cascading screen image....

After disconnecting the strips from the T-Con and checking the resistance in diode mode on each spot you marked I am seeing .0L on my multimeter. In resistance mode I got OL in both directions as well....

Here is a view of each side of the buffer board at the bottom of the display.

Hello,

I'm working on a Vizio Model V555-H1 that displays a cascading series of horizontal lines when first powering on. These lines appear to be in the shape of the Vizio Logo and descend until reaching the logo before resetting to the top and continuing their descent. I have reseated my TCON board and dusted connections but still have this fault displaying. I'm familiar with vertical lines but this one is a new one for me. My research into this problem hasn't yielded results as keyword searches point back to vertical line problems.

Anyone have any recommendations? I...

Hello,

I'm Garret. I am a new owner at a local company that offers IT services. I have a background in micro soldering phones, consoles, and other low and high density PCB's. I've decided to formalize my skills by diving into Macbook Repairs and need some schematics to do it. I am currently the only person in my area offering ANY kind of soldering repairs and I'm looking to level up my skills prior to pursuing a degree in electrical engineering.​
