The set is under a year old and is under warranty. The LVDS cable inside these sets have a history of coming loose. The problem could be the panel. Either way, the set is the problem and needs to be looked at. This set is worked on in the home and does not need to be taken to a shop, so, you can still use it. Contact Samsung at: 1-800-SAMSUNG Hope this helps.

I think you need to exchange the Main Board.

SOURCE: I have a 46 inch Samsung plasma HP R4252 picture went black

Probably the power supply that drives the video has gone bad. Samsung recommends the TV go to a service center. If you have some skill and are willing to try, open up the back of the TV, remove the shielding and look at the boards to identify any obvious damage. Leaking or bulging capacitors, soot, scorch marks are the obvious. (Other parts can have bad solder or tiny cracks that are hard to spot.)

http://www.shopjimmy.com/catalogsearch/result/index/q/HP-R4252 has reclaimed parts for this TV. These are parts from TVs that were damaged in shipping and were only run during quality control tests. They list several power supplies for the model so check what part number is actually installed (there is usually a label on the board).

I hope this helps.

Which part causes backlight flickering / dimming?


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electro-medical.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Samsung 46" LED - Screen goes to black every 15 sec and then comes back shortly. Do I need to replace tcon or main or is there something else possibly wrong?


Hi Todd,
Screen goes black means back lights go off. The power supply may not be responsible for this problem. Please check back light on command from main board. Good luck.

Bottom half of screen is black


The display strip is not properly seated in the connector base. That is a hardware problem so dont think of a software error.

Samsung 46 LED get sound no picture


it sounds like your back light inverter has gone. if its a led it could be built in on the power board. so check for bulging or leaking capacitors on the power board.
