Hi,

there are many possibilities

a) turns on and off - might be on the power supply board

might be bulge or dried capacitors on the secondary side of the chopper transformer

b) color appears to be double -- convergence problems

might be open fusible fuse, or capacitor

c) more gray -- digital circuits


Initially can be check by a visual inspection of the boards, then the voltage checking on some points.

important is the B+ it determines the status of your TV, once it is noted some points can be isolated and checked.
include the make and model of your TV .

hope i have helped you, thanks for using Fixya!

How can i check my lamp ballast in a rca scenium 50w151 everyone tells me its my color wheel because i replaced my lamp and since then my tv wont even start up the light blinks then it stays on for a while...


are you sure when you replaced the lamp you seated it correctly, no really hapens all the time so dont feel bad. also another common error is the lanp door is not seated or closed and locked properly that is the most common problem that happens after a lamp is replaced, or the new lamp is bad never throw out your old one as somr dealers will give you what they call a core refund , they reuse the case around the old lamp. some can be worth as much as 50 to 60 bucks!!!

Its the color wheel assy. Its changing speed due to worn bearings. You may also hear a hum coming from the rear of the TV. Seek an RCA authorized service center to resolve this.

Color blinkig in and out.


It seems like the color wheel might start to fail.
Do you hear any abnormal sound(s) from the TV when ramdon color appears.
Would you be able to check and make sure all the fans are working properly?

Dlp 50 inch


sounds like the DM3 isnt powering up the ballast to light the lamp or the ballast may be faulty. i would suggest trouble shooting the DM and ballast voltages.
