Re: Replace or repair light tunnel

I have a RCA Scenium HDLP50W151 with a collapsed light tunnel. The tv has worked with no problems for over 8 yrs and still has a great picture so I would like to fix rather than replace the set.

Re: RCA 50" Scenium Screen has dark top?

Well I ordered a rebuilt light engine from TSM rather than try to fix the light tunnel. The light tunnel is no longer available for purchase.

Re: RCA 50" Scenium Screen has dark top?

Remove the screen? Really? My understanding is that the light engine removes from the rear. Is this correct?

Re: RCA 50" Scenium Screen has dark top?

Ok. Just checked. It's already on long life. Is removing the light engine pretty straight forward? I'm very mechanically inclined and not afraid to take it on. My background includes high end audio and restoring vintage audio equipment, but it’s not my profession. Thanks again for all your help! Brian

Re: RCA 50" Scenium Screen has dark top?

grayfox the mirrors have not fallen at all. They have shifted much like a parallelogram due to heat is my understanding. My understanding is that the mirrors are glued together as a rectangular box and the heat from the bulb causes the glue to soften and allow the mirrors to shift. Am I right to ass...
