My rca r52wh74 turns on for 10 secs then off.

That model is famous for having issues with the deflection board failing. Replacing the deflection board should solve the issue. You can get replacement deflection board for the ITC222A chassis from www.tvrepairworld.com under the RCA circuit boards catagory.

Sounds like the bulb went out.
Go to http://www.purelandsupply.com/RCA-Projection-TV-Lamp.html and order a new bulb for under $200.
They are easy to intall; a screwdriver and 10 minutes.

Have you tried the TV in more than one outlet to make sure it is not an outlet power issue?

three strikes and it's out... rca does this, it is just showing it has tried 3 times for you and untill it is unplugged it won't try again.. you need to provide model #.. could be a few different things
hissing usually meens you have high voltage...that's good but then what don't you have?
ctc 169 - 179 could be high voltage divider... need more info

This could be a number of things, but sonce the set is only 6 months old, it should still be under warranty. Call to request warranty service .

Dan

if u have only had it a month it should be under warranty get them to repair it

how the inverter checked out

I would contact RCA support, and they should be able to provide you with the authorized RCA service centers in your area.This is the RCA customer Service number 580-634-0151
