Re: Sony un50h5500 washed out image
So just an update...
Cm603 was almost burning hot to the touch, so I pulled ic chip from one of the non matching boards for swap. After completing reinstall of the swap chip it was still hot to touch but I noticed that the color settings were now slightly better, so I fiddled with controls and options cycling through to see if it could be made right
After 10 minutes of fn with settings, the picture snapped to and the overheat of cm603 ceased and is now cool to the touch while in operation.
Ultimately I swapped...

Re: Sony un50h5500 washed out image
Correct, but you never know if you're getting a fully functioning one when oreldering used. And I already wasted 30 on the shopjimmy board. I already have one on order, but figured I would try repairing since I have the required tools and skill. Just need schematics. Right to repair needs to hurry up

Re: Sony un50h5500 washed out image
Ok, so I swapped some parts from sj board that was a non match with original board.
Swapped cm608 ic and p12 voltage reg. (voltage on regulator is 3.3v on left side and right side is 1.2 which I thought was vr output and was also supposed to be 3.3v)
No change, but ive now noticed that the cm603 ic which is the smaller ic on the right hand side is extremely hot. However, not sure if this ic is interchangeable. Anyone know for sure, as i could find no data sheets for any components....Leave a comment:

Thx, you are correct. I'm going to sort it out and see if it can still be saved....Leave a comment:

Re: Sony un50h5500 washed out image
You are correct on both accounts. Odd that it works exactly the same on both board, but i did in fact order the wrong part. Time to order another, although I may try to swap the cmi pwr driver ic to see if it fixes the issue. If not then I'll order the correct part.
Also, not sure why I got sony stuck in my head, it's definitely a samsung. Thx for getting me back on track....Leave a comment:

Re: Sony un50h5500 washed out image
With the fact that the issue is the same on both sides when alternating cables, does this make it more likely that the issue is a defective part order was received?...Leave a comment:

Re: Sony un50h5500 washed out image
Thx for responding. I tested with alternating discommect of the tcon ribbon cables and same washed out result on each side. 100% of screen image is visable, but dull/faded display that has a white washed haze....Leave a comment:

Sony un50h5500 washed out image
Picture of tv is washed out, but all features are working and visable. There may be a slight blur to the text, but not sure that's just a result of the washed out effect, or a sign of something more, as i ordered a t-con board replacement from shop Jimmy and got the exact same results.
From what I've gleaned from the web, this issue is usually due to a bad cmi ic chip on the tcon, so either I got a bad board from shop Jimmy with the exact same issue or there is another possible cause of this issue that im missing.
Any guidance is appreciated. -
