Question about RCA R52WM24 52" HDTV Projection Television
First to isolate the loose connection from fault, check the cable connectors from the lamp and the ballast board. Pull-out the cables and then re-insert. Also check the ballast board from bad solder joints (crack/cold/dry joints). This is hard to spot I would advice you to work in the brightest area or use table/portable lamp to locate it. Once found, re-solder it.
You have to check also leaky/dried electrolytic capacitor in the ballast board and its power supply. This will do the same symptom. You must have a capacitor checker because not all of it bulged/dome at the top.
Another parts concerned is the lamp itself. Once near to its peak burning life it will produced an intermittent fault like what you've experienced right now.
If you don't have necessary tools and test instrument and can't do the job yourself, I would advice you to look for a qualified technician to troubleshoot the unit.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

You may want to check your cables. If this is hdmi fed, a power surge could have affected the video input. Try changing inputs on your tv. If it persists, you can spend the money for another hdmi, do this if you only run surround sound through the hdmi otherwise, try switching the cable to color stream (compnents) Red, Blue, Green, with Red and White audio.
