Hi I am Vortash first I need to know why you think it is the colour wheel ? and secondly do you have a schematic or a manual for this set and what is the model number , all I know so far is that it is an RCA .. I may be able to find out the stock faults for this set or the troubleshooting guide .. you can contact me here on Fixya or if you wish .. the documents that may help you will be on these two sites http://www.safemanuals.com for the instruction manual and http://www.eserviceinfo.com
for the service manual and full shcematic diagrams with easy to follow fault diagrams .. There are quite a few reasons why various televisions don't work after a lamp replacement but to be honest I have never heard of the colour wheel being one of them ( unless the lamp exploded and damaged it ? ) but there is always a first time for everything lol , I would suspect more as you have already changed the ballast circuit a fault on the power supply first and foremost and as the sound is ok a general fault in the return signal to the ballast to say the lamp had'nt sparked as I say a number of reasons .. I gather you are some distance from a repair depot or service engineer so here is my email Vortash@hotmail.co.uk if you have to get any material I can email from here .I will search my data base and if I come up with anything new will add it to the comments on here ... regards Vortash

The color wheel and fans are supposed to come up and run before the lamp/ballast is activated. If the fans are running, look at the color wheel. If you see that the color wheel is not running, that means that it is not the ballast or lamp causing the problem. The color wheel drive voltage can be found at connector CN110 on the DMD board, pin 4. If that signal is present, replace the color wheel. If that signal is not present, but the fans are running, replace the DMD board. If the fans are not running, look on the digital board. It has 3 LEDs. They are, from left to right, 5v standby, Digital 5v switched, Fan 7v switched. If any of them are not lighting up when you try to turn the set on, you probably have a power supply problem. Look at the SMPS solder connections. I have had only one SMPS go bad, and it was not supplying correct voltages on the Digital 5v and Fan 7v lines. You could also have a color wheel or DMD board problem. Either of those can cause no startup.-------------------its the colour wheel problem in your unit.that too needs replacement.this will solve the problem.thanks.please do rate the solution.thank you for using fixya.keep updated.
