Question about Samsung HC-R4755W 47" HDTV

1 Answer

I'm trying to use my HC-R4755W as a display for my computer but cannot get the entire desktop onscreen. I've fiddled with every control on the TV and display properties on the computer, but the edges are all clipped. Any advice would be appreciated.

Our Samsung tv will not turn on/power on. It sounds like it starts to power on, the light blinks twice then you hear something, the light stays on solid after that. This model usually has an audible tone...


I would suggest two things you need to examine :

First remove and examine the lamp to make sure it is not shattered or fractured.

Second examine the color wheel that faces the lamp (see attached photo) and if you had a fan like sound or high pitched whine before that points to the color wheel.

The color wheel is a do it your self replacement (I can help) and takes less than a hour.


Let me know what you have tried and if the lamp or color wheel are intact.

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..
