Question about Samsung TXK2754 27" TV

Samsung txk2754 menu won't show up

My tv works fine. The menu board won't show up so I can make adjustments. I know the menu works cause I can push menu and try to adjust things blindfolded. Would be a problem if I had a picture of all the menu board, then could do it blindfolded. But I can't find a service manual that shows them anywhere and don't have the copy that came with set.

SAMSUNG LCD TV very bright screen

hi Elle924.
this is all i could find out.
What kind of panel do you have - a LED or CCFL one? If it's CCFL then check the inverter board. The main board might be fine (changing the brightness settings changes the signal to the inverter board) but if the inverter board is faulty somewhere then the problem you described may be caused by it
or try this forum.

Spots on screen in front of picture

This could be an issue with your DMD board or your Video Board. Go to the menu, if the white spots show on the menu, the issue is with your DMD board, but if they don't show, the issue is with your Video board.

Problem with Samsung TV

SAMSUNG Convergence Problem


It looks like blue convergence. Look at menu, select convergence and see if blue top is bent down on convergence adjust screen. Probably won’t adjust.

Some Samsungs have convergence IC’s on a separate convergence board in the back of the TV. Others have the IC’s mounted on the main deflection board. Either way the board has to be removed to get at the dud IC’s and associated burnt resistors.

You remove the appropriate board, determine if any resistors are burnt or damaged, replace any burnt or out of tolerance resistors, replace 1 or 2 IC's and re-install the board.

Now you have to adjust it to look like new.

If the unit has not been misadjusted and everything is OK now, running the auto focus may put the picture back to it’s previous stunning quality, as it was before IC failed.

If after self or autofocus it is still misadjusted noticeably, try the customer convergence adjustments. Operators’ manuals are available on web through searching.

If convergence can not be adjusted properly, you messed up chip install or resistors may be wrong value or open; or it needs major adjustment.

If you live around Calgary, Alberta try me instead:

Or try to the find the repairperson part of this website (on the Homepage) and search postal code. Maybe you will be lucky and someone from your area is listed for Projection TV repair.

Most rookies doing this job will cause damage and not be successful. They will pay double for someone to fix their mess or end up scrapping the TV. It is not a simple task. It is more difficult than batteries on a remote.

Good Luck

Samsung TXK2754 27" main board cracked after fall

You would have to contact the manufacture. a better solution would be to take it to a shop and have them repair the board. It would involved using acitate glue and the bridging the wire traces back with wire bridges (jumper wire soldered to the traces). If you are not able to do this on your own a local shop could do the job.
