Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
Have an older RCA DLP TV with a dark picture on TV or DVD. The picture seems clear, but you have to sit very close to see it.
Replaced the Bulb but no help. Wondering if it needs cleaned? I went into Menu to see if calibration settings were off (blackness level all the way up) and they were normal.
And no, this isn't the model of the TV but this program will not progress without filling in the space. I just want general information. I don't have the model with me, but, there must be something common to DLP TV's which cause the pic to be dark. Or, if it is a circuit board, then I can call RCA.

Check that when you turn on the TV the Lamp is striking (turning on).
My thoughts are that you will have to reset the lamp hours counter to make it work, as the TV does not know that you have replaced the lamp. To do this, check the leaflet that comes with the lamp - it should explain how to reset the counter for the lamp hours.

SOURCE: RCA DLP/HDTV Vertical Lines
This is djb1 who commented above on the vertical lines that have gotten progessively worse. I may have found a potential solution. I unplugged the TV, took the back door off where you replace the lamp, took the lamp out, changed our vacuum from a vacuum to a powerful blower and blew ALL visable dust off anywhere that I could. I paid special attention to the heavy dust that was on the TV blower fan blades and around the mirror. I also held the blower on the outside of the TV on the vents around the lamp door.
After I plugged the TV back in, the lines have disappeared. We watched TV last night for about 2 more hours and the vertical lines never came back. So far this morning, the lines have not come back and it has been a couple hours as well.
It's worth a try. The free solution may be as simple as clearing out all dust. LET'S HOPE IT'S A PERMANENT SOLUTION!!

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!

I have the exact same TV and have had the exact same problem. I talked to a TV repairman who said it has to be my deflection board. I just found this out today so I am looking all over the web for a deflection board. I hope this helps! Tyson
