Question about Samsung PCL545R 54" Rear Projection Television

1 Answer

SAMSUNG PCL5415RX-XAA - Audio OK, but screen is dark, has no images.

Hello everyone,
I have a SAMSUNG PCL5415RX-XAA since 2002, it has been a great TV but now is showing some flaws.

First the image was all green and then it went blackout, several trials later to turn it on again I can heard the relay clicking, but the TV powered off right away, then I thought that something shorted.
After reading some of the threads on this site, looks like it could be that any of the boards are indeed shorted; so I opened the TV set looking for signs of fluid leaking, but I didn't find any, then I just blew the dust off and tried again.
Now the TV turns on and stays on, and it has audio, but the screen still dark, it has no images.

I'm troubleshooting following the flow charts on the service manual page 5-3, titled "No Raster (Sound OK)", I pretty much understand all of the steps except for the first one, "Check Heater"; on the wiring diagrams I have seen the a couple of lines marked as "Heater", but it is just a line, it doesn't relates to any electronic component.

What is the "Heater"? Is this "Heater" the same as the heat sink?
If so, what should I check on the heater (heat sink)?

Any recommendations to help find the delinquent components?

Any help will be greatly appreciated.
Thanks.

How do I fix a Samsung tv model htp5054x/xaa? I have power and I can hear audio but no image.


First trouble shooting steps is to try a different source, or at least a different cable. A bad HDMI cable can allow sound but not image. Also look closely at the screen. If you can see a dark image, it would indicate that the lighting system has failed. Check this video for some tips. Samsung Plasma TV Repair How to Repair and Replace Main Board

Dark screen on samsung lnt4669fx lcd tv, what could be the problem?


As you suspect, it might be of T'Con board fault. Check all the flat cables connected to T'Con to panel should be checked first for any loose contacts. Re-seat them once. If you wish to know more, check this site. It has illustrations of screen shots, for Samsung LCD TVs, with a faulty T'Con board. Can compare these images with your TVs.

Samsung 32 lcd tv backlight off after 4 sec. audio ok


If your TV is staying on and you hear audio after the picture goes dark, then you have a problem with a CCFL or the inverter circuitry that drives them.

Most likely an inverter problem.

Like a bad xformer (usually fogged up plastic wrapper)

Or a bad cap (bulged, swollen, cracked)

Or maybe a shorted IC or transistor (test for short circuit between the different pins of the device)
