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

1 Answer

Colours serparated, not converged, screen looks concave

Was given a Samsung HC-P4741W television but the colours are all crazy and neon and they do not match up. Looks like a psychadelic 3D show, with double and triple picture. Also the screen itself is not damaged, but there appears to be a rounded shadow at the top and bottom and sides that makes it look as though it is concave. Is there a website I can download a user manual for this television? Do these problems sound like the tv is beyond repair, or would it be worth calling a repairman?

Your TV may have a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

Problems aligning convergence hc-p4753 projection


Hi,if the converence is wildly pinched in say one corner compared to the other colours then it is most likely that your convergence circuits have failed for that colour. - Warning,Not an easy fix without circuit schematics and can also be costly for the IC's too

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.

Bad color scheme - cannot adjust enough


If you haven't already done so, it may be that all you need to do is adjust the convergence after moving the set. You should find convergence and its adjustments in the setup menu

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.

Colours all messed up and reds dull look brown


You should first turn off all the color on the set, or play a b&w Tape or dvd. What were looking for here is, what the color balance or grey scale looks like first. If a B&w video or whatever looks true to grey and black and white then you have whats called croma problem in the color or video demodulator. My friend I wish there was an easy way to assist you in this type of repair but theres not, as it could be a problem in the video/croma demod section of the video jungle IC and this is not a user serviceable part or repair as thers several issues concerning Hi voltage as well as x ray radiation. Now if its a problem where the grey scale or the B&W is not true to color then theres a problem in the R G B driver circuits. Could be a simple drive adjustment or even a soft or weak picture tube. I hope if your not a tech you seek a pro to assist you in this troubleshooting as this could be dangerous for you as there are no user serviceable parts inside this set. Good Luck
