Question about Samsung Televison & Video

1 Answer

Samsung LCD TV diagnosis. Possible tcon board?

Mod #LN46A55OP3FXZA. On start up picture normal. After 10 sec Green hue takes over certain gray scale colors. This happens on whole screen while there is something on the screen. When screen is empty (Stand by) normally there is a black back with blue "pop ups" with "check signal cable" and input details (HDMI 1). Screen is now a dark green. Center "popup" is normal. Upper left pop up has black strip on top (normal) and the rest is the same green with the boarder still visible. When in menu back is black (normal), menu list (normal) selector is dark green. When in TV input mode (coax) "static" no signal is normal white,gray, black pixels (normal) but pop up stating no signal (normally just blue) is blue but with red horizontal lines running thru the top few inches of pop up. Only in pop up. While watching TV all colors are present and normal other than the green that appears to only effect certain black/gray color scales. I am thinking Tcon. Can you confirm or point me in the right/better direction or possible remedies. Thanks

Most likely you can adjust it in the Service Alignment Mode (SAM).

Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:

Red = 135, Green = 128, Blue = 133.

The "Cool" and "Warm" menus are deltas from the "Normal" settings:

COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13

Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

Since the lines are vertical, the image is lost sideways and the corruption changes with the image then clearly this is a sign of Y-Sus failure, not the Z-Sus or the buffer boards.
An logic or input board failure would affect the entire screen, not just a part of it and a failure in one of the buffer boards would affect strictly defined lines of pixels and the defect would be constantly there all the time.
Since you haven't told us the exact model i can't point you to a replacement board.

Why does the screen turn white after 10 minutes?


Probably the t con board have problem. the power regulator ic on the tcon board make this problem. As ist an smd ic you have to go for a new tcon board, because its not possible to replace the ic with normal soldering irons. you need smd rework station for that purpose. And also on more thing in some tvs the t con board is integrated to the lcd panel. if so its not possible to replace only the t con board , you have go for a fresh lcd panel. it would be a costly repair. because the panel is the costliest part of the tv. Any why check the video to understand which one is the t con board. if you find one in yours then try to replace it with new one. hope your problem will solved

I have a samsung lcd tv that powers on has sound but the picture is fuzzy and has no colour . What would be the component that needs replacing for this ??


Hello. Before you start replacing parts, make sure your connections are correct. It sounds like you have connected a composite source to a component input. Composite is three RCA plugs, a yellow for all of the video, and a red and white for audio left and right channels. Component is five RCA cables, green, red and blue for video, and red and white for audio. if composite is connected to a component input, the picture will be black and white with squiggly lines all through it.

My LG HD tv screen has a wide, gray band on either side of the picture


Try changing 'perspective' or screen ratio.
This may work, but could also stretch the picture too wide,
On my non-LG TV this is called 'aspect ratio' under the 'picture' menu.

We are having SAMSUNG LA37R81B tv at home its showin blurred picture we asked repair man he said we need the tcon board number so that we can buy we now need your help


Hello,
it possible that the problem is the the TCON board, you can try websites Shopjimmy.com,Ebay.com to buy a refurbish board for the replacement.

Also note that
The T-CON (Timing Control or LCD controller) board (on the LCD panel assembly). It transfer the universal image signal of TTL and LVDS signal to specific TFT (Thin Film Transistor) LCD.
This is the interface board that talks to the Logic board and the LCD panel to produce pictures on the screen. White/gray glowing screen when it fails or not getting the voltage from the logic board (the 5 or 12vdc is supplied by switched transistor on the logic board). Notes: T-CON board is mounted under the metal cover shield.
Common failures:
Scrambled pictures, Lines, multiple pictures, color smears/blotches, rolling pictures after warm up.
Blown surface mounted fuse.
No pictures, very dark screen almost like there is no backlights.
Hope this helpout..
