Replaced lamp and still doesn't light up Tv

Did you replaced the cover for the lamp? If not, the TV will not power on. When the cover is replaced, it closes the switch and allows the set to power on.

I have the same problem on my rca serial# hd50lpw166

It seems more to be an issue with your ballast, of course this is if you replaced the lamp before, but regarding the clicking sounds it's most probable to be your ballast. discountdashmerchantdotcom, the ballast aren't that expensive, they're around 60 dlls

My RCA 50'' DLP Rear Projection TV will not turn on

Hi, This could be several things as the power goes everywhere. Long distance troubleshooting so hang in there. First try a cold reboot by unplugging and replugging after 30 minutes. If nothing check P1 on the light engine for the following voltages: pin 2 5vdc, pin 3 3.3vdc, pin 9 3.3vdc, pin 12 12vdc. If any of these are not good it is the formatter board. If all are good, does the color wheel spin at all. If this is OK then check J4 on the light engine, the ballast enable line should be 0 vdc in stby, .5 vdc at turn on, and 2.5 to 3.25 vdc in run. If good, is the light engine trying to fire the lamp? If not, inspect the J4 connector and the lamp power supply, If they look OK then the lamp ballast is probably bad. This will give you something to do for now, Good Luck!
