Question about Samsung PCL545R 54" Rear Projection Television

Black Lines when picture is bright

I have a Samsung PCL545R its having an issue with black lines that flash horizontally when the picture is suppossed to be white or bright. I can adjust the contrast or brightness to eliminate them but then I end up having to watch the TV very dark. I dont have any manual for this TV I bought it from a friend wen it worked fine. Is there a contrast module that may be going bad or something else? Ive called a repair service but he wanted to bring the TV in and charge another 100.00 just for that. Please help me my kids ae driving me nuts Thanks

Re: Black Lines when picture is bright

Are those lines all the way up/down your set? Or just in small zig-zags?

The brightness is very dark. Any nightime scene

Your CRT's getting old. Plus dust on lenses don't help much. You have to open front frill (below screen) and back of the TV. Clean up lenses using dry paper towels, do not wet.
In front of the TV after grill remove center cover and locate "black box" that have 6 potentiometers on it that looks like plastic adjustment screws for philips #2 screwdriver slots. 3 of them should read "Focus" These you don't touch. Another 3 reads "Screen". Put some still image on your screen (like paused DVD movie frame). Carefully add brightness in all 3 colors trying to avoid horizontal lines appearance. If lines show up, just turn it back a little. Try to keep color balance looking at the picture.
This procedure will brighten up image but further reduce CRT's life.

In case that you posted wrong model here and you have DLP Projection TV - just replace the lamp.

check the high voltage with the screen control turned up high where there is no raster. suspect problem within the video circuit where there is no high voltage or defective picture tube.some time when the screen is black and the screen control advanced,you can see if the tv has video or vertical or horizontal problems on the screen.service the high voltage circuit if there is no raster or high voltage is raster can be caused by the no heater or filament in the CRT.---- a defective picture tube can cause many problems, such as, poor brightness ,missing colors,intermittent picture,poor focus,a single-colored raster,arching in the gun assembly,retrace lines in the picture,negative picture,chassis shutdown,noheater or filament lit and no raster to name a open filament or heater can cause no picture or no raster symptom.a defective CRT can have an extremely bright screen.loose particles of the cathode element can lodge between the grids and cause an intermittent black and white picture. simply tap the ends of the CRT gun assembly and notice if the picture begins to flash off and on.---- with a leaky picture tube after turn on the raster dims and get extremely bright.a dim picture with no green in the raster can result from a bad green assembly. a heater-to-cathode short can cause a raster to change colour or a result in no raster at all.replace the picture tube if there is severe arching in the neck of CRT. excessive brightness with retrace lines and a vertical collapse to a thin line can be caused by a bad coil on the neck board of the picture tube.rejuvenate the picture tube when there is very bright green screen. check for the resistance change on the resistors of the CRT neck board for an excessively bright picture with retrace lines.excessive dust inside the CRT spark gaps within the picture tube socket can cause the very bright raster and the chassis shutdown.a defective video amp,luminance buffer,or reference transistor can cause a bright picture with retrace lines. -------- for getting any required parts to replace you can get it from or from or from --------- thanks.please do rate the solution.thank you for using fixya.keep updated.

Picture Problems: Snow, color, lines

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix herebb0cf99.png

Black horizontal lines

Sounds as if you have a bad capacitor in the horizontal deflection or video circuitry. You can spot a bad capacitor in circuit with a ESR meter.Hope this helps.

Black horizontal lines on mitsubishi VS-5043

Is the noise in all inputs (line, tumer) ? If it is in the tuner alone, check the coax lug to see if you knocked it loose. This could be the problem. Check you picture with a DVD player on the Video input. Let me know what you find.
