Question about Samsung HC-R4755W 47" HDTV

1 Answer

Flickering Screen I have a 4 month old samsung HC-R4755W CRT projection tv, not under warranty anymore since I purchased it used. After about a half of an hour when the TV warms up, images on the screen, especially dark ones start flickering. Any idea on what is causing it? Or how to fix it? How much it will cost?

How do I remove the outer case, shell, on a Samsung hc-r4755w projection TV? Need to get to the back of the screen to clean it, cat puked down front of TV and got behind screen

there are two screens back to back and I think if you look from back with rear cover removed you will find the debris is between them.

Not going to be easy or simple to deal with.

Samsung HC-R4755W turns on and off by itself.

Have Capacitors checked in the power relay circuit, also if you have young children who like to push the buttons on the front of the set make sure none of the buttons are sticking inward or stuck in a pushed in posistion. More then likely it might be caused by a faulty System control board which we call the signal board, or bad connections on the power supply, Have a tech check the connections on the Flyback transformer and the High Voltage Deflection Area on the HV Power supply. I believe you have Cold Solder Joints in the HV Power Supply.

Hope you this helps you..

Cracked Lenticular screen


How old is that TV?

Order from here:

and specifically:

Wow! I think that's a rear projection TV, so it may be time for a new one!, as the part is about $175 + shipping, + installation + your time, + they break pretty easily.

Good luck.

This is a problem with the CRTs(picture tubes) or the coolant chamber(s) of same. The cost to replace the affected parts with be quite high. Expect to spend $400-600 to replace the CRT(s)
