    However when I connect it to computer the problem doesn't occur at all. So do you think it is back light problem or board problem?
    Waiting for reply.

Hello johnque,

I would suspect that this might be a back-light problem. However this may also be a screen issue. There are many things this could be and it will require that a person troubleshoots the unit to actually find out what is wrong. I know you wanted a quick fix for this but this unit has to be diagnosed, so to that end, if you have a background in electronics these are the tools you will need to complete this task;

1) A schematic diagram of the TV
2) A Multimeter
3) An Universal Video Analyzer or Computer Monitor Analyzer
4) An Isolation Transformer

With the tools and knowledge of electronics this becomes an easy problem to solve. Now if you do not have knowledge of electronics I would suggest that you take your set to a qualified TV repair shop for servicing.

Thank you,

    Since you say this the problem could be on the board where the TV inserts signal, vs the connections where the Computer inserts signal you will still need a schematic and equipment to trace the signal from both inputs.



    Let me know how this turns out.

How do I fix an occasional black screen on a Samsung LN46B630?


Sounds like T'Con board fault. For some models of Samsung LCD TVs, this part is built in the panel, means non-replaceable. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Samsung LCD flat screen goes black. Turn tv off and back on it's fine for about 15 minutes and keeps doing it.


Sounds like your power board is failing. contact samsung tech support and describe your problem. some parts on samsung have lifetime warranties and the service call is free.

Samsung le32r black screen


Hi.

Your problem sounds like inverter has failed.
To prove this you need to remove the back from your tv set.
Then switch it on and look carefully through the small holes on the metal shielding that is directly over back of screen you are looking for bright white light.
If you cant see it easily try doing again but in A dark room.
If you can see white light through the holes in metal shielding the inverter is working & fault is else where.
If no light can be seen problem is with inverter you will need to remove the inverter pcb & check the transformers with ohm meter to see if one is open circuit. Allso look on same pcb for any smd circuit protectors that may be open circuit.

Samsung 32" LCD HD TV Problem


I would first try replacing the cable if the problem remains the same it will almost certainly be a bad connection on the socket or panel in the back of the TV.

Simple to solve if you have any soldering/TV repair experience.
If not take to the repair shop, it shouldn't cost a lot to put it right.

Tv freezes, goes black, starts again


I had a similar problem, mine was a bad earth connection on the main (tv input) board. it earths through the screw mountings so check they are screwed in nice and tight, probably best to remove and then refit it.
