I have a RCA 50" DLP Scenium I've had since 12/07/2005 and let me tell you it's been one of the best tv's ever.  The picture quality and sound cannot be beat for the price I paid.  I've replaced the bulb twice and just after replacing it the second time, my wife and I were sitting watching one night and it just went off.  The lights on the front blink on and off approximately every five minutes and that's all it will do.  No sound, no picture, no nothing.  I unplugged it, waited a while, then plugged it back in but nothing would happen other than the lights in the front blinking as before.  I've called around and was told by one repairman that it could be a module inside the tv that costs around $500 from RCA and would be about $100 or more to change out.  However, this may not be the problem.  I've since bought a 55" Sony VVega (quality nowhere near as good and the sound is horendous).  Now my RCA I love dearly is sitting in a spare bedroom on the dresser, and I have no idea what to do with it.  I certainly don't want to have to spend $600+ to fix it as I've found a brand new one for $899 online!  I don't know if anyone can help, but I thought I would at least ask.  Thanks!!

Is it always true that the power supply failure is characterized by popped caps that are visibly failed? My tv failed in a manner consistent with what folks are talking about here, but all of the caps on the PSU board appear in tact and firm.

Thoughts? Thanks!

January 4, 2010 2:21 PM

Are the caps flat on top or are they rounded? If they are rounded, then they are popped and need to be replaced. My caps were in-tact, but popped. I personally don't know what else it could be. Hope this helps a little.

I'm not sure then. At www.discount-merchant.com they sell the power supply for the tv. Just type in the model number in the search bar and it brings up all of the parts. HD50LPW175

The clearance man! please help me!

I have the HD50LPW175 from RCA aswell.

Just bought a new bulb, and new ballast.

TV fires on now, but goes off after 5 seconds of being on.
Indicating bulb error code, but im being forewarned its the power
supply board.

Id LOVE to replace the caps if you can throw in a lil more advice.

of idiots and half witted guess's.

I have an RCA DLP 50" HDLP50W151 that I bought in Oct 2003, that's working great BUT there's a translucent purple band on the right side that appears to be growing. Any idea on what the problem is OR how to fix it ? Thanks !

FYI. this is info before cap. replacement:
new bulb, new ballast. tv turned on .. after a few tries, goes off about 5 seconds later. goes thru cycle. and does the same thing again, turns on, turns off.

So i seen this forum last night..
and so this morning..

I goto Radioshack, get new capicators. Bad thing is that they only sell 35V, not 50V. So anyway, I got the 35v.
I seen that someone suggested moving up to the 50, but since the stock ones were 35V, i didnt think it would be that important, besides the longevity of it before it blows again.

I get home, change the stuff out. Put it all back together.
Same issue, tv goes on, few seconds later , goes off.

[edit-the TV's sound remains on though, JUST the bulb is going on, off, on, off, at the interval of trying to properly boot up. ]

After leaving it on, letting its do its thing for a short period of time, maybe 5 minutes, I try to do power on, switch channels, switch inputs.

Boom. Tv stays on. So i left it on for like, 15 minutes, to try to let it warm up, maybe put some power thru the capacitors.

So i turn the tv off, and try to see if it will boot up first try or not. Well it doesn't, but, I have gotten patient, and have gotten it to fire up a few times, doing the same methods of patience, warming up, and input changing.

Btw my old ones WERE NOT puffy, in any way.
So what can this be related to? Light Engine? Dm3? Anyone?
The colors on the tv are perfect, and there aren't any crazy grinding sounds or nothing like that.

I mean, i seen on the other page it said "First, change these 4 capacitors" , what would be next?

I have a 50 rca hd scenium also, and the bulb blew, when I pulled the bulb housing out, what I saw was a lot of white particle, so I removed the panel and with my modified vacuum cleaner and compressor, I blew and sucked until it looked brand new. How my picture after all this, is a little fuzzy. Do you recommend cleaning the lenses?

February 24, 2010 2:38 PM

I also have replaced my caps [which did not look popped] and my tv doesnt turn on correctly, but it DOES turn on and stay on.

I have to hit the power button, and once the blue lights start i hold channel down , making it cycle through all the inputs until the blue lights stop, then awesome, Tv stays on, and works great.

$5 in parts from radioshack, instead of the $140 board from DM.

i have a rca modle # HD50LW175YX12 projection tv. replaced the bulb but no the problem. tv will turn on flash 5 times pause a few seconds and then turn itself off. does anyone know what the problem is, the power supply was fixed a few year ago. is it the same problem if so what do i need to do. does anyone have a skematic of the power supply? please help me do not want to spend a lot of money fixing this problem

I have had the HDLP50W151YX1 now since 4/04. Fairly satisfied with features, but on my third bulb now. Bulb #260962 from Suburban Electonics if interested (just get the bulb not the entire housing as the bulb is easy to replace. About $125 back in 08 about $80 last time. Not sure if this helps but had audio humming problem which turned out to be color wheel failing, it finally actually blew apart the other day. Easy to replace just some small Torx screws and delicate unplugging of two cables. Other problem in the past was what some of the posts describe: picture going black and then blue power-on light blinking, also clicking noise from back of TV. Turned out for me to be the small switch that gets reset when you replace the plastic door after changing bulb. My solution was to dump the door since the area gets way too hot anyhow and just tape the switch in the tripped position ...worked just fine and the bulb lasts longer due to better ventilation. Hope this helped. Hard to find parts for this beast since RCA is basically out of business. China anyone?

Yup, my hd50lpw150 went out after replacing the color wheel. It was good for two weeks, then lost the picture. The sound was still there and sounding perfect. At first I thought it was the bulb, so I replaced it and still no picture. So I opened the back and all I hear is very light hissing sound coming out of the board where all the resistors are. All my green resistors (35v1000uf) have a flat top but I think I'm going to replace them anyway. I did find one puffy top resistor, and it's the black 3900uf 16v, there are 2 of them and I will replace both and hope that will be the fix. I will post an update to see if it worked. Thanks for all your comments and posts, they've help me out alot.

This is the number for the color wheel for the
RCA Scenium HDLP50W151YX1 I mentioned in previous post.
Got it on ebay ...OEM color wheel #267888. Easy to install
just need Torx drivers. Be real careful disconnecting wiring
harnesses, it's real easy to break em. Works great now and no more
high pitched whine either, which I guess was the color wheel bearing
going bad. I have to admit though that this is a lot of crap to go
through for a tv that's only about 7 years old!! Maybe Samsung next time?
