Hitachi 50hyt62u-k tcon or driver boards ?

[Chrissygizmo]

Hi everyone.

This is my latest problem, I have a Hitachi 50HYT62U-K tv. I was informed off the previous owner that it had been squirted with water.

I originally thought it was going to be a right off and I would be stripping it, but I've messaged around with it and I've had a good picture on it earlier.

I have got the problem down to either the tcon board, ribbon cable or driver/buffer board (Not sure what they are called) . I have messed around with it with hammer hands & I've managed to snap 3 of the clips that keep the ribbon cables in place on the tcon and driver boards so I've been using plastic strips to try keeping pressure on the cables , when I turn the tv on and rub along the ribbons I've had a split second of a good full screen picture. I will upload screenshots of the video I took while doing this. I would be really grateful for any help on this.

Thanks for your time

Guess the place to start would be a replacement tcon, a lot of times they're pretty reasonably priced.

Hi

Thanks for your input, I'm going to have a go at glueing down the ribbons from the top obviously so I don't get the connections dirty to see if that works first. I'm not sure if it's a good idea so I will wait for a comment first

I'm going to try glueing down the ribbons to try and get even pressure over the length of the strip first, I'm just not too sure if it's a good idea incase I make the problem worse ( like I usually do ) . Just waiting on a comment first before I go ahead

I don't think it's a good idea myself.

If you glue them down and it works then great, but if it fails would the ribbons be in a fit state to attach to a replacement board?

I have found the problem (or probably caused this problem) ... The ic on one of the ribbons that feed the screen from the tcon board has burned out, melting a small hole in the ribbon, I definitely had a full screen picture on a couple of occasions when messing around with the driver board ribbons, but I'm sure I saw a brief smoke signal while doing this, now I know the screen is kaput unless there's a way of renewing the ribbon.

This may work if you're up for it. Example of cof bypass there, might need to find one that gives a better step by step process but there's a lot of such videos on youtube: https://www.youtube.com/watch?v=YacI7hWWKJw

Same sort of problem on JVC 49" 4K TV

Would be best to start a new tread since its a different TV although an identical problem.
