Samsung LCD model #LN32A330JIDXZA has a very bright color, can hardly see the picture


My problem began the same way, then the tv turned off everytime I tried to turn it on. First I opened the tv, made a list of all the electrolithyc caps values and temps in the power board and gone to the store and bought all except the bigger one (like USD 8) changed all the caps and then the tv didnt turn off again but image was all white.

Then searching in youtube found about the t-con board issues but the entire card was too expensive to dump so searched how to repair the t-con and found I can change the main chip so bought 2 in ebay from china took like one month but was just USD 8, so carefully cut all the old chip legs, retired the chip, used a soldering iron to retire the old legs, cleaned, put bits of new solder in the tracks, placed the new chip and began to paste leg by leg, tested continuity and checked for solder bridges between legs, assembled, turned on the tv and half screen has strips bot the left side was ok so rechecked flex cables between t-con and lcd and found bent tracks, carefully repositiones, assembled and now my mom has a brand new samsung 32in LCD to watch CSI and stuff... Sooo F_ck u Samsung LOL

Hope you can repair yours, every problem is a world so may not work for you but for USD 8 in chips, patience and some pulse soldering i think it worth the try.

I have a Samsung Syncmaster 930bf monitor, when I turn it on, I can see only white. Backlight is working but there is no picture. I tried both video inputs, no difference. Capacitors on power supply part...


It sounds like the ribbon vable between the logic board and the T-CON board on the LCD panel may have come off or it has blown fuse on the T-CON board, or not getting the 5Vdc from the LOgic board to the T-CON board due to bad 5vdc switched transistor that supply the voltage to the T-CON board.

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..

The l950t tv is power on and the screen is white totaly. Audio ok and channel change is ok


Check the connection between the logic board and the T-CON board on the LCD panel assembly, check the fuse on the T-CON board for 5vdc on the fuse of the T-CON board.
Look at LCD panel album to see what T-CON board looks like.

T-con board for your samsung


The t-con board is very easy to replace. The only problem is you need to take a bunch of stuff off before you can get to it. How to replace it:
1. Take off the back of the TV
2. Unplug all the wires connected to the middle boards, you will need to take off the whole assembly that the 2 boards are attached to, the main power board and audio/video board.
3. The t-con board is under the shiny metal cover near the top of the TV. There are four small screws holding the cover in place. (You should be able to see the cover when you take off the back plastic cover of the TV).
4. There are 3 connectors attached to the board. The white one that comes from the audio/video board and 2 small ribbon type that connect to the front of the TV, probably the LCD panel.
5. The 1 separate connector is self explanatory. The other 2 are a little more difficult. They just slide into place. When you look at the connection, there is a brown "flap" holding the ribbon in place. You need to flip it up from the top side of the TV.
6. The old t-con board just comes out and the new one goes in.
Hope this helps!
Let me know if you have any other questions.

Pico fuse


It's on the T-con board itself at location Cp1 which you will find printed on the board itself.. The fuse is a tiny s/m (surface mount fuse but you can use a pico fuse of same value. According to schematics it's a 1.5a fuse. Simply solder one across the s/m fuse and if it opens then change the board. Samsung p/n# Bn81-01286a
To test the fuse use a VU meter set to continuity.
Pico fuses are readily available at almost any electronics supply outlet. I get mine from ACME Sales in Florida (least expensive) but even your local Radio Shack might sell them...

Samsung LNS 4692 lcd tv t-con board


The fuse is located just upper right to the connector that attaches to the main board. This is a SMD pico fuse that is rated for 3 A @ 32 V DC that protects the Vin bus. Replacing the fuse may not fix the problem as it has most probably opened because of failure of another component.
