based on your description of the sound, i would guess that your color wheel shattered (somewhat common on dlp sets). i've never heard of baird as a brand name, but you could see if you can find the part online for replacement, but sometimes these parts are astronomical in replacement costs and it's ...

this looks almost identical to my PS. take a look at the caps outlined in red here: http://img.skitch.com/20090904-kajwf6gt9gen5a774mka6uei2h.jpg Replacing these caps fixed my issue (of blinking lights for 5 seconds, solid for little bit and then turning off). I had a local shop do it here for $30 o...

mitchkramez

have you check the capacitors on your power supply? i feel like a broken record suggesting this, but these RCA tv's have lots of problems with bad caps on the psu

mitchkramez

could be a couple of issues, the fact that it works, and then turns off sounds like a heat issue, i would take the back of the tv off and clean the ballast fan and any other amounts of dust you find in there first and see where that gets you...

mitchkramez

yeah, you'll have to take the back of the tv off, it's very easy though

mitchkramez

could be the ballast not firing the light, you'd likely hear the color wheel if it were bad. if you pull the bulb out and shine a flashlight in it's opening, you should see the color wheel - if it doesn't look shattered and you can't hear it, you're probably ok... you can try and remove the bulb and...

mitchkramez

have you tried taking the screen off to see if there's any residue on the mirror, lens or the back of the screen itself perhaps?

mitchkramez

if you had an arc, you're lucky it still works - better to use a lightbulb with some wires to slowly drain big caps like that -- anyways, it's possible that the arc re solidified a bad solder joint or something or perhaps you just had a loose/bad connection between the ps and the ballast, or the bal...

mitchkramez

that's too bad, sometimes it's an easy fix, and sometimes it's not. i think based on the problems you've had, your logic is sound, time for a new tv -- and not an rca this time i hope :) i was just at sams club last night - they had a 50" panasonic plasma (display model) for $675... i wish i had mor...

mitchkramez

Let me know if you decide to throw the TV, I might be interested in the power supply (mine has a coil that hisses pretty loudly)

mitchkramez

hello again, in your original post, you didn't mention what your tv was doing (the blinking lights) it's possible that you have some bad capacitors on your power supply, this is exactly what happened to my tv, on for 5 seconds, blink 5 times and off. Check over the power supply for any caps with puf...

mitchkramez

i think the voltage going to the bulb will blow out an average multimeter when it's firing the bulb -- 15,000v. I won't pretend to be an electrical engineer, but knowing i was dealing with that kind of voltage was enough for me to bring mine in for a check up.

mitchkramez

the power going to the ballast is DC i believe -- but i don't think you can measure the power to the bulb w/o some expensive equipment

mitchkramez

hmm, that's a good question -- i have m50wh72s, which is nearly identical. i checked my bulb hours in the service menu the other day and i was at about 5000 hours (this is still the original bulb). for reference, this was used for a year (by the previous owner) it then stopped working, and they put ...

mitchkramez

Do you mean 5 seconds solid then off? Do you get sound? Do you hear the color wheel spin up? The more information you give us the more we can help!

mitchkramez

tony, that looks like the ballast board, i need the power supply --

mitchkramez

my shop says i have a bad coil causing a hiss, but rca doesn't make that coil anymore -- does anyone have a line on a coil for this tv or even the whole power supply? The part number (i think) is 270341R

eddie, it's coming from the inductor on the buck regulator section of my ps:

mitchkramez

guys, i'm stumped and need some help determining what the problem is: there's is a relatively loud hissing coming from my power supply. it sounds like a tire losing air, not a buzzing or a humming. physically, i don't see any bad capacitors on the board (I've replace 4 that were bad). I'm wondering ...

mitchkramez

from everything i read, the color wheel should spin up even with the lamp removed (make sure you have something holding down the lamp door switch or nothing will happen :). 321v might be ok, another user reported 324 or so on their 50"... You won't really be able to test the power coming out of the ...

mitchkramez

it's probably worth looking to see if you have bad caps. 310v seems pretty low, it should be 320-380v... and the fact that nothing is spinning or starting up, seems like a power supply issue... the color wheel should spin up first if everything is working ok.

mitchkramez

That's pretty much exactly what mine did, other than the tv would turn off after the solid light was on for 5 seconds. I'm not sure what that red light is, but mine has the same thing and it's actually inside the inputs cage if you open it up. I didn't have any fans, nothing made any noise, but as s...

mitchkramez

redman, found this on ebay... exact same part number at 1/3 the cost...

mitchkramez

does that look like your ballast board? mine looks very similar to that, but i think it might be more narrow. i'd call them to verify that it will 100% work in your TV and ask them about their return policy if it's the wrong size or something. i haven't heard of that site, but at $160 it's much chea...

mitchkramez

redman, I don't think the ballast has a separate fuse, the only fuse i know of is on the power supply, and that's got to be intact since you're getting power. I won't pretent to be TV repair person, but apparently if you have the right tools you can test the caps while leaving them on the board - no...

mitchkramez

Ouch, that lamp ballast seems to be very expensive... the cheapest I saw was $350! Hopefully, if it is the ballast it can be repaired, or maybe it's just some really cheap caps. I noticed in another forum that you got an OSRAM bulb, before spending any more money, I'd return the OSRAM bulp and get a...

mitchkramez

No problem redman -- Do you have any blinking lights on the front? The color wheel does make a little bit of noise when it spins, so that's probably fine, unless it seems overly loud. If you have blinking lights... and possibly even if you don't, it's probably worth sliding out the tray the Power Su...

mitchkramez

does it blink 5 times and shut off, or blink 5 times repeatedly?

have you pulled out the power supply to look for any puffy capacitors or burn marks around capacitors or any leaking electrolytic?

mitchkramez

Eddie, thanks... i actually brought it into the shop this morning because the power supply was hissing everything worked fine still, it was just kinda irritating :). Hopefully they'll find something simple on it and just be able to replace a few more caps (I don't see any others that are bad visuall...

mitchkramez

if you have a multimeter you should check the voltage coming from the power supply -- set your meter to DC and put the probes on the two pins where the plug that runs to the ballast is. If you see somewhere between 320v and 400v your ps is probably ok... and since the bulb is most likely fine (since...

mitchkramez

just picked up my board from the repair shop. 4 capacitors were bad, the two i found and the other two i mentioned above (even though they looked ok). got the board home plugged it in. and VIOLA! IT WORKS! That's to everyone who helped!

mitchkramez

This seems obvious, but all over the internet, people misread this simple observation....

5 blinks, pause, 5 more blinks - rinse, repeat

IS NOT THE SAME AS

5 blinks, 5 seconds solid, tv off.

If it's the first, then it's likely the lamp, if it's the second you've got bigger problems.

mitchkramez

here's a picture of the bad caps on my power supply... hoping to get this fixed tomorrow... notice how the tops of the two caps in the front of the picture have bubbled tops... they're not flat like all the other capacitors... that means they're bad...

I have the same thing going on, the first problem we have is that we bought an RCA ;) My power button was blinking 5 times also, my TV is 3 years old so i'm thinking the lamp is bad! It wasn't, took it to a TV repair place and they said it was a bad color wheel, so I gotta color wheel coming from R...

i have a rca m50wh72s. the power light blinks 5x, stays solid for 5 seconds and the turns off. no sound, no picture. the fans don't turn, i hear an incredibly faint whining from the ballast, but i have to put my ear right up next to it to even hear that. I've also noticed a small red light inside th...
