Question about RCA D52W19 52" Rear Projection Television
I have a RCA D52W19 52 in. Rear projection. When I turn the t.v on, it makes a weired start up noise like an electric shock coming from the back. I unplug the t.v for about a minute, and then try it again, and the samething. Now the t.v will not come on, when I do plug it in it makes three short noises and then will not start. Can anyone help me with the problem, I have heard that this well known with this t.v, but would like to know if it worth fixing, and what parts I need.
Look to see if the Lamp has shattered. If so, vacuum out the shattered glass pieces. Replace the lamp with a new one. Hopefully this will get you going again. Lamps are common to fail but there are not cheap. a cost of 250.00 to 350.00 is a common cost. I do not recommend the cheap aftermarket lamps. They are not reliable
Hope this helps,

I don't know if you saw the countless other posts on this exact problem, but I 99% gaurantee a lamp is not your problem.
I believe the high pictched noise you're refering to is the high voltage when your tv attempts to power on. When you say your tv turns on, is there anything on the screen? What I have experienced with several RCA itc222 is blown capacitors. When I attempted to turn the tv on it would try 3 times and then make me wait 45 seconds to try again. I don't know what to tell you about the blue light as I have never experienced that. But here is my solution if you'd like to try and fix it yourself. Be careful, but it is very doable.
I almost garantee that you need to replace a capacitor. You can check to make sure that's what you need by unplugging the tv, taking off the back cover and feeling the top of 3 capacitors. On my d52w20, CP150 (rated at 2200uf 16V) was blown and the top was bulged out. You should also check CP120 and CP114 to see if either are blown. I don't have a clear picture of where it's located, but I have a picture of what you should see after you take off the back cover.
In the middle of the picture you see an aluminum heatsink in the shape of a 'C' with the opening facing away from you. That is where CP150 is located. CP120 and CP114 should be located nearby, but if you can feel a bulge on any of the tops of those 3 capacitors replacing them should fix your problem. Replace the existing capacitors with a higher voltage rating of either 25v or 35v.
"4 capacitors on the power/deflection board. CP110 220uf 200v. CP120 220uf 35 Volts. CP114 220uf 35 volts. CP150 2200 16 volt. also check entire delfection board for cold solder especially around flyback. bad connections here can cause problems like some of the fp fuses blowing and cutting off convergence supply"
