Question about Samsung Televison & Video

Open Question

I have a Samsung LCD tv model #LN40B530P7FXZA, and for some reason the tv just started "blinking" the picture going in and out even if we switch to DVD. The sound is fine and my other tv's that are hooked up to the cable play just fine. I've unplugged it for 10 secs and plugged it back up with no results...PLEASE HELP!!

Call Panasonic customer service. This is a well-known problem (I had the exact same problem with my television) and Panasonic will send over a technician to fix your television. I needed two new parts to be installed. Once the new parts are installed your tv should work fine (although now my volume doesn't work).

SOURCE: DVD plays only in black and white

Hey, I had this problem on Thanksgiving Day, trying to watch a dvd on my mother's HDTV. You should be able to hook up most standard dvd players to hdtvs. First you have 3 cords, mine were red, yellow, and white. The connections go as follows:

HDTV:
Audio| Component. The white cord should be in a white audio slot. The yellow cord should be in a yellow component slot (video) and the red cord should be in a red video component slot labeled Pr/Cr. Make sure you match the component numbers. For instance, if you want to use component one, then hook all of the cords into the slots for component one. Most hdtvs have multiple component hookups ( think multiple "channels" for your game system, dvd player, etc) so it's important that the corresponding cords go to the correct component slots.

DVD:
Match the yellow and white cords to the appropriately colored slots. The red cord should go into the slot labeled component video out Cr/Pr. Not the red audio out. This worked for me. Hope this helps.

This depends on whether you have digital cable box or not. If you have a Digi Cable Box look for the red/white RCA output and connect this via RCA cable to the Red/White Audio input on your surround.

If just Basic Cable look for a red/white audio output on the back of your televison. connect this to the Red/white in on your surround. Could be called tv in or auxillary.

It sounds that there should be a dead short circuit in the power supply board's circuit. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electric shock. Instead, contact any experienced service technician, or the nearest service center.

Ok i have the samsung model ln40b530p7fxza and the tv will power on but not screen. i can hear the audio of the tv and any unit that is hooked to it but no video at all. the back lights dont come on...


The 24vdc feeding the backlights inverter is present.
For the backlight to come on, it needs BL_ON signal from the main baord, 24vdc from the power supply board.
Please read my guides to understand how LCD TV works.

46" LCD Samsung TV Model# LN-S4692D I have no picture


The back light inverter board may have gone out or it is not getting the 24vdc from the power supply module. Start checking for voltage feeding the inverter board.
