i mean it could be like instant on and off to fix it. i'll try that vacuum. any idea which DMB board i would need, or do i have to open it to find out? I recommend you to take it out so you can see the exact part you need. also seems like if i plug something into comp1 or 2 it wont see it. i've tri...

Angel

Hi comptom.

If the menu is affected the problem is with your DMD board, however, since the problem go away when turn OFF and ON, I think this problem appears when the DMD board overheats. My recommendation: Vacuum the light engine, that should help.

Angel

Could you please post some pictures of how are you measuring the voltage?

I think the power supply should receive a signal before output the 320/380 Vdc, so it's possible that the output to the ballast wasn't 320/380 Vdc all the time. Let me investigate about it...

The instructions are not for my model but I'm assuming the process is similar.

Jerry

Exactly, all the Samsung DLP models are almost the same.

Hope this could give you an idea.

Angel

Hi Jerry.

Here is a color wheel replacement guide: http://guides.fixyourdlp.com/samsung/bp96-01579a.php.

You be the judge ;)

Angel

There are a few possibilities.

What is the wattage and gap of your old bulb?
What is the wattage and gap of your new bulb?
What is the wattage of the ballast?
does the wattage of the ballast match with the new bulb?

Have checked if is there any dust on the lens?

Angel

Unplug the TV, wait a minute and plug it back. Then turn it back ON.

In Mitsubishi TVs after replacing the lamp and turning the unit back ON there should had been a message asking you if you replaced the lamp? Press ENT(er) for Yes or CANCEL for No.

Hope this helps.

Angel

Hi tcslucky, your first problem is most probably the lamp. However you have nothing to lose if is not, since you'll need a replacement soon or later.

Your second problem (the flickering) seems to be in your analog board. Replacing it should solve the issue.

Hope this helps.

Angel

Check your color wheel. It could be damaged that would explain the vibration.

Angel

There are 2 fans. You can easily locate them with this guide: http://www.jangro.com/electronics/dlp-tv/samsung-dlp-how-to-replace-fan-2/.

You just need to vacuum all the dust ;)

Angel

They're usually swollen from the top.

Actually I checked your manual before I posted, and there is no code of three leds ON.

Angel

Most probably this is just an overheating issue, so before trying to replace anything I recommend you to clean all the air vents and fans.

Get back to me once you do this...

Angel

I tend to agree with you and even questioned them about it. Their opinion is that there really isn't any processing of the component inputs on the analog board . They've agreed to have a technician come to my house and replace the digital board for free so figured I wouldn't argue too much. Hopeful...

Angel

Have you checked if you have any inflated capacitors on the power supply board? Normally this leads to your symptoms.

Angel

What kind of info do you need?

Angel

Update: Tested HDMI/DVI input. No color problems. Tested cable Antenna A input. No color problems. Looks like it's only the Component 2 and Component 3 Inputs that exhibit the problem. Talked to the repair shop again and they are now saying they suspect the digital board they installed is bad.........

Angel

Well, if you already checked the bulb and is ok, then the problem is most probably the ballast. However, have you checked the color wheel?

Angel

hi jared.

The problem you have is not with the switch. If the switch wasn't taped correctly then the ballast wouldn't try to ignite the lamp. Your problem is most probably the ballast.

Hope this helps.

Angel

Hi Brian.

Check this guide: http://guides.fixyourdlp.com/samsung/bp96-01579a.php

Hope this helps.

Angel

Upon plugging it in the power light is lit for only about 5 seconds & then shuts off. If I push the power button again it will light for 5 seonds & then click - goes off. No whirring sounds, no blinking of the power button light - lamp looks good. Any suggestions appreciated! Ok, I'm gettin...

Angel

Which board are you testing?

Angel

jcc56 wrote:OK, is "HDMI" input the same thing as "DVI"? There is not an input labeled HDMI. Anyway, I assume DVI would bypass the analog board so I'll try that when I get home (if I have a cable). Thanks for the replies and your help!

Yes it's the same :) Let me know how it goes.

Angel

R819 - located on the right of the centered upper heat sink - its one of two pink resistors (orange/orange/yellow/gold striped) & it reads infinity the matching one a bit to its right reads 319 ohm - Can this be the problem? It may have been touching the heat sink - still reads bad when I moved...

Angel

Try the HDMI, I think the problem is in the analog board. Check also if the menu is affected by the red tint, just to discard a DMD failure.

Angel

Ok, first of all:

How did this problem start?
Did your TV turn off suddenly? or It just didn't turn ON one day?

Do you have sound?
Did you have sound when the TV turned OFF? (if that is the case).

Angel

Hello everyone. I have a samsung dlp. My picture will be perfect and then at any time the screen goes black. No flashing lights or anything. Still has sound. From what I have read it sounds like a ballast problem. Is this something I can fix myself although I have never worked on a TV before? Also ...

Angel

Does this problem happen with all the inputs?

Angel

Ok, it seems that the problem is with your ballast, it might be having falls of voltage, so every time this happen the lamp turns off.

My recommendation is to replace it.

Hope this helps ;) ...

Angel

When the TV blacks out... do you still get sound? or it turns off completely?

Angel

Do you have any other symptom after the 2 hrs of being ON?

This problem usually happens when there are some inflated capacitors, but I've never heard of this problem on Samsung DLPs. In Mitsubishi DLPs is more common.

Angel

Did you reset your lamp timer? instructions here: viewtopic.php?f=10&t=92

Do you hear any clicking noise? Then your ballast is the problem.

Hope this helps.

Angel

There's a possibility that you got a defective lamp, however before return anything I'd make sure the bulb is seated properly inside the enclosure and the enclosure is connected correctly to the ballast. It could also be your ballast, actually if your lamp is a good brand and is new this is more pro...

Angel

I replaced the bulb in my samsung MLP5063WX/XAA - I did read about the cover being on before would work. I checked the switch and put the cover on. Now I get sound but no picture. If I use the remote, the timer light lights. What am I doing wrong? Try resetting the lamp timer first: viewtopic.php?f...

Angel

Yes, most probably the reason for which your lamp is going out is your ballast.

Angel

sRGB stands for Standard RGB (Red Green Blue). More info at: http://en.wikipedia.org/wiki/SRGB

And You can use whichever you like.

Angel

Most probably the problem is the lamp.

Hope this helps.

Angel

Yes, I'm still thinking so.

Angel

I think your problem could be the DMD board. It doesn't sound like anything else.

Angel

Actually there are a lot of them, for example this one: http://www.discount-merchant.com/We-provide-factory-original-parts-worldwide-p/1078426-samsung.htm.

Angel

Steven.

Do you have the exactly same problem than danr?
When the TV turns on, do you get audio and video?

I think your problem could be an overheating issue. in that case cleaning the fans and air vents should work.

Angel

What is your part number?

Angel

My recommendation: buy a Philips bulb! and be sure you get the right one to avoid this problem.

good luck with the return ;)

Angel

Well, as you can see in that link, the same part number is used in a lot of TV models, so it's possible that one of them is the one for yours, my recommendation is to take out the switch and look for the part number on it.

Angel

Actually the ballast suggestion was for someone else :lol:

Yes, definitely that switch could be the problem, you can find it here:

Hope this solve your problem.

Angel

Hi Bsnman05. It seems to be your ballast. When this device fails the TV thinks the problem is with the lamp since it's not turning ON, so it shows the three leds blinking. I think the only two devices in your TV that can produce that noise are the ballast and the power supply, but when is a power su...

Ovadoggvo, or anyone that can send me down the right path; So, about 6 months ago my DLP (hlp4663w/xaa) started taking for ever to turn on and off. Well a few days pass and one morning I go to turn it on and I heard a pop, so I figured it was the lamp. I opened the back and pulled the lamp out and ...

Angel

Well, when this happen, 90% of the time the problem is the lamp, the other 10% could be related with some other device. However if you buy a new lamp and that's not the problem you would have a spare, so you have nothing to lose trying that option first. Have you ever replaced the lamp? How old is y...
