Samsung ua55es6800m(xxy) incorrect main board - odd screen issues

[Lewisjones]

Recently acquired the above tv from a dodgy repair man, to try repair myself.
Please disregard white horizontal line#

The right bottom part of the screen displays perfectly in more of an oblonge/round area than what the picture shows

The rest of the display is quite dim, grainy, shadow in areas and overly red.

Also there is a ghosting or slow frame rate in the top right corner
During boot up, colours run to the upper right corner

The main board Inside is actually for a 32" and not a 55"
Apologies, out and forgot to right code down. Starts with ur32 on sticker and appears to be from a ua32es6200 cd01

Also there is an issue, once metal frame is put back on the top 2 / 3rds freezes the picture (no big deal but might be related). Does so with frame connecting top right hand side

Would the compatible cd01 board for a 32 be causing these issues on the 55 panel?

Backlight looks great by the way. Not an issue. Also all ribbon connections have already been played with

Most definitely as the LVDS cable may not have the correct No. of wires to carry for a 55in and the software would be different, hence the upside down screen. You are lucky in that the 32in Main Bd actually gave a picture with the original T-CON Bd and Panel.

as suggested, potentially you are lucky to see a picture. Having said that, boards for different size of sets can be all the "same" depending on the design. Since you have a picture, I would be surprised if the connectors are significantly different as they would like not function if that was the case. Any you can likely check the "interchangeability" of boards by going thru some site like shopjimmy which usually has a pretty good "xref".

Further, I would say your set has a problem with the tabs / drivers based on the very thin horizontal line (if I am seeing it correctly) along with darkness on the side of the screen. I would check the tabs to see if there is some form of damage before investing much more in terms of cards (unless they are free / kicking around).

Thanks for the reply guys.

Tv is stripped to panel to investigate and his upside down to play with the tabs.
# horizontal white line is cause by one tab and goes away when pressed.

The board which I found in there is for a ua32es6200mxxy but it's an as01 where the 55 panel (despite being a similar model) is a cd01 type. Shop Jimmy has no references of this type of es6800 tv.

I did read elsewhere that the wrong main board would cause problems. I'm surprised there is a picture on the screen too. Given as01 probably isn't really compatible with cd01 (they would most likely be different panels all together?)

Quite keen to purchase the correct board and try it out.

All you guys know more, so I appreciate anyone chiming in.

Also, are all t-con boards for the same tv/s usable in terms of Europe (ue) or north America (un). Obviously main board would not have the correct cable/aerial input and power board would certainly not work.
#somewhat not related to above, but I'm very I interested to know

if you have a tab issue, a replacement main will not rectify this.
