Did any of this work for you, Sam?

Eddie

I'm pretty sure you can type it into Discount-Merchant.com and still come up with the right product.

Eddie

You don't need to replace that. If you buy a new one from DM though it'll come with that paper, but it's supposed to protect in-case of explosions or something... I think its more of a liability than anything!

Eddie

Awesome

Eddie

Oh no! Call David at DM, he's a good rep there and he should be able to handle it. Tell him Eddie from Fixyourdlp.com sent you. There might be a problem with the lamp, but he can trouble shoot better over the phone than I can. If you still have your old lamp, I'd advise trying that one to see if it ...

Eddie

This is common and it's most likely the color wheel.

Eddie

I'm not too familiar with DLP sets using LED lamps. The thing you have to be aware of is probably the color wheel if it's giving you a reddish tint. If it's like the traditional DLPs, the LED is just a light source for the DLP chip. Then the colors are provided by some sort of color wheel I think. T...

Eddie

depends.. it's got something to do with either the lamp, ballast, or power supply. That's my guess. If you haven't replaced the lamp, you might want to try that first.. if you've already replaced the lamp, check the power supply to make sure none of the capacitors are blown out.

Eddie

Lamp?

Eddie

Think you can post a picture of it? It's possible the DMD chip gets dust on it. It's definitely not from the lamp. What do the dots look like? big? small? blurry? sharp?

Eddie

Yikes, sounds like it might be a light tunnel!

Eddie

The spring helps to hold the assembly in place. Did you figure it out?

Eddie

That's not enough information... The lamp is always the best place to start. Make sure the lamp is a Philips lamp first of all. Was there discoloration when it died? What kind of noises does the set make? Did you close up the back cover? There are a lot of things you've got to check -- that being sa...

Eddie

The color wheel could be going bad... it hasn't happened yet, but that's what a bad ball bearing sounds like inside a color wheel. You'll start to notice color anomalies eventually and then the TV will stop turning on.

Eddie

Sounds like it might be the lamp. I'd buy the whole lamp unit from DM. They have a warranty on their stuff, so if it goes out in the first 6 months, you get get a replacement if the lamp is defective.

Eddie

That just sounds like a bad bulb. I'd get a new one to check it out. If you've had it for a few years, then it's definitely time for a new one. Otherwise, it could be a ballast issue or something keeping the lamp from igniting. From you post though, it sounds like the lamp.

Eddie

DMD chip or light engine, I'm afraid... the bottom half the screen is black too? might be light tunnel.

Eddie

Osram bulbs are bogus. It might also be the ballast or power supply.

Eddie

No way, that's a light engine.

Eddie

That's a strange problem.

Eddie

Or you can just buy a refurb board from DM. Shouldn't cost that much! discount-merchant.com

Eddie

You'll never get continuity on lamps like this. They don't have anything solid connecting the terminals, it's all gas. Gas ignites with voltage and lights up.

Eddie

It really depends on the type of projector you have. The 150W is obviously a lot lower than the 200W. If you also replace the lamp driver, you're definitely going to have a compatible lamp and ballast, but was the projector made for use with 50W higher equipment? It might burn or melt something.

Eddie

that's awesome!

Eddie

how old is the TV?

Eddie

Who said you needed a new light engine? I'd check dealers and service centers. DM may have engines? They have like a billion parts in stock?

Eddie

Yes, it is normal for the connection to be open because all lamps fail continuity tests. Unlike household lamps, these lamps use gas to generate light instead of a filament. The only way to test a lamp is to arc it with the ignition voltage necessary to light it up. And the only real quick and simpl...

Eddie

at first thought it could be a stuck button somewhere. .. either on the remote or on the button set on your television. could be the IR code too on your remote i guess. you can get a brand new remote from DM to see if that fixes the problem. if not, check the buttons on your tv to see if it's stuck ...

Eddie

the hissing could be another form of magnetostriction from the power supply... can you get a recording of it or try to isolate where it's coming from?

Eddie

Hey, check with DM. They might have some dead boards for you. I'm sure all you'd have to pay for is shipping.

Eddie

do you have an LED lamp in it, is that what you mean?

are there any other symptoms? a storm or lighting storm perhaps that could have caused a short somewhere? LED lamps don't just go out!

Eddie

depends on what kind of samsung tv.. you've posted in the dlp/lcd projection so i'll assume it's a dlp... it might be the video board. during the lighting strike, the board may have shorted somewhere. if you can find a replacement board, check Discount-merchant.com, you might be able to save your TV...

Eddie

bright to dim can be a few things.. there's a board that controls the brightness/contrast.. that could be bad.. or there's a power supply problem.... or you still have a ballast problem, which helps to regulate voltage to the lamp. let us know what you come up with!

Eddie

that indicator works for the whole lamp/ballast system, so maybe there's a problem with the ballast. perhaps take it into the repair facility to ask them to see if the ballast is arcing. the ballast needs to shot high voltage into that lamp so if it can't do that, the lamp won't like up. if the prob...

Eddie

Nice to have everyone on board here (pun intended).

Eddie

It clearly looks to me like something to do with the DMD board, but since that may not be the case, the most highly unlikely seems to be the video board. I've never seen it act like that, not have I see it look like that with cables either...

Eddie

This might be a silly question, but did you check your cables?

Eddie

Redman, I've heard of Soundandvision, but they are UK. You'll pay wayyyy more than you would in the US.

Eddie

A description of how bad the TV picture is will help.. Lines? Distortion? Pixelation? Those things are extremely helpful in determining if it's a DMD or color wheel issue. You should also take out the lamp as that may be the culprit. Lamps can last 2-3 years easy, but it's not unheard of for them to...

Eddie

Glad you got it figured out. Those RCAs are notorious for bad power supplies!

Eddie

i've seen a few retailers on ebay. one that seems pretty cheap is http://www.starlamps.co.uk. don't know a whole lot about them though, you might want to check em out, or give them a ring.

Eddie

5 blinking lights of DOOM!!! Well there are usually 3 or 4 different defects when these lights come on: 1/2: Ballast/Power supply 3: Color wheel 4: Lamp. Most likely it's a lamp, but since you've ruled that out, I would say it may be the color wheel. You should ask the tech how they came to the conc...

Eddie

Hey there. Sorry to say that techs can't always check the ballast and lamp combination. Some say they check it, but you have to be aware of how they check them. You can't check the lamp without a ballast, and a ballast that simply arcs doesn't necessarily mean it's working. The ballast is a very sen...

Eddie

Well, it sounds like there's no power going to the display portion of the TV. It could be one of the buffers or x/y sustains losing power as well. Have you taken it to a TV tech?

Eddie

It's hard to make that determination without the actual wheel working. I'd take the wheel out first then spin it. If it's not spinning correctly, or you hear winding sounds then your wheel is the culprit. Chances are, the wheel is what's bad, not the DMD board.

Eddie

Hey parts guy, Discount-Merchant.com usually has tons of parts, but for your Panasonic, I think you can Google "Ballast Repair Kit" and you'll come across a few things that will help you repair your ballast. Also, the split button can be found on some of the newer Panasonic remotes. I thin...

Eddie

We don't have any wiring diagrams here, but you could try and post some photos of your damage, or lamp to see how we can help to restore it.

Eddie

flashing pixels can be a product of a bad sustain board or buffers. Can you be more specific on your repair?

Eddie

Where did you buy the parts? Samsung Authorized Reseller means nothing to this forum. We go with OEM parts from Authorized OEM providers.. a whistling noise might be a color wheel

Eddie

The main things that cause the lamp to stop working is:

[list=]the lamp itself.
the ballast
the optical engine, or light engine--whatever you want to call it.[/list]

Basically if one of those components is bad, it'll tell the entire TV to stop working.
