Question about Samsung HC-P4741W 47" Rear Projection HDTV-Ready Television

1 Answer

Rear Projection TV Picture is all green with Horizontal Lines

Within the first 5 minutes of turning the unit on (3 year old Samsung HC-P4741W 47"), the entire picture turned green with horizontal lines (tv show images were still identifiable). Initially, this would flicker in and out, and then eventually stayed this way upon powering-up. (At first it seemed to return to normal after "lightly" tapping the side of the unit.)

It looks like you started out with an intermittent solder connection which may have been fairly easy to find early on. Now, unless a technican can make it come and go while tapping on the circuit board and repair the connection, it may be a very expensive shop repair.

My 2004 samsung self focus bbe digital tv had a normal picture, but recently the screen started producing yellow images. Everything we watch is in yellow tint. The model number is HC-P4741W. If anyone can...

Check and make sure that you still have your red component cable hooked up and it is tight on both ends of cable. If cable is tight, try another cable to make sure the one you are using isn't bad. If you still have a yellow picture, stick your head in the unit and see if the red tube is lit. If it is not, you found your problem.

Samsung HC-P4741W has no picture and no sound

Doubt it is the convergence board. It is in shutdown mode caused by an overcurrent or overvoltage condition. It will take some troubleshooting to pinpoint the part(s) that are defective. Could also be a cracked solder joint.

Greenish haze on my Samsung HC P4741W

If you purchased it new then this clearly should not happen - if it is second hand and therefore older then the red tube could be burnt out. The convergance may simply require allignment if the set has been knocked about trying to get it to its final resting place - this would need a tech on site to set it up.

Samsung hc-p4741w flashing red light

That sound is made by the power supply who's gooing in protection mode due to some overcurent in secondary. Could be many reasons: conv. amp. IC's, video amp.IC's etc. In my opinion more then 70% chances to be the STK for convergence. Need to be troubleshooted by a tech.

Picture Looks Like a 3-d Movie

This is bad convergence. Try self focus and if still not ok is hardware problem. The STK are leaked and need to be replaced. It's not easy, you have to remove the all deflection board and for sure you'll have some resistors to replace too. I sugest you to call a tech, but first try the self focus.
