:?: good, lets us know what they tell you, there's similar posts in this forum with different TVs! I think it could help them if this is an easy fix, Its easy for techs like me 'cause we have junk engines laying around :P

Hello, well judging by the fact that you have no distortion or weird noises, I would replace the lamp first, however do not dismiss the possibility of the ballast. :?: It could have grown weak over time, or maybe some static shorting some components out during the move... :oops: the facts vs questio...

grayfox

:D "its been shipped" lol. but yes some do come with the metal casing and after further reviewing I noticed the plugs, hopefully everything will work out fine 8-) if not were here to help! :!:

grayfox

oh ok, I would start by replacing the lamp but not rule out the ballast...

grayfox

yeah depending on what part of the supply is damaged it can cut off for certain parts, and yes you would be looking for no voltage, but be careful!

grayfox

I don't think you need to worry about the model number, my doubt are with the pictures, I would contact the seller and make sure this is not a DMD board (because of the metal casing...)

grayfox

what a shame :(
If you are familiar with using a multimeter you can test to see if the ballast is receiving voltage (ruling out the power supply). But as for the ballast output I would not recomend testing since it feeds the lamp 15,000 volts for ignition! It can damage your tester!

grayfox

Hello, it really depends if this lens is lenticular or just plain glass, either way I was not able to find a replacement part and I would not suggest you "replacing" it with a part just made to those size specs. maybe if you contact RCA you can find out if they sell this part separate and ...

grayfox

Hello, I think it might be time to replace the Input board and hope the DMD board is working properly (since that comes with the complete light engine). hopefully the input board has some damage in the audio processing section and it needs to be replaced... here is what it looks like http://www.disc...

grayfox

Hello!

Judging by the fact that a digital signal is affected, like the xbox and the menu, I would rule out the DMD and land on the Digital Video Board or Input board, Next I would try Analog VS Digital video inputs to see which of the 2 I would replace first (i.e. HDMI versus a Coaxial input)

grayfox

Hello, this is actually a very common problem especially with Mitsubishi and especially after changing a lamp :roll: ! 90% of the times this happens it is because of a weak ballast, it generates 15,000 volts to ignite the lamp, which is why it works on if you turn it and leave it on, (ignition occur...

grayfox

Im sorry! Technicians from Samsung came to your house and gave you this information? :shock: or where they just certified by Samsung? :P I still think this is just a lamp issue, if you do any research online you will find only one indicator light pops up in the front when you have a lamp or a ballas...

grayfox

Some light engines come with a colorwheel, but no they are 2 separate parts, one is the complete engine with the projector and DMD board, the other is the colorwheel by itself or the metal enclosure. The cheapest part would be to try to find the bare colorwheel for the TV and try that, but it is an ...

grayfox

hhmmm that is a lot of research :o I think you can try the Digital Video Board first, it is relatively cheap and easy to install, you just have to make sure you order it by model of TV AND the board number off the part, since these all look the same and some are for different screen sizes :|

grayfox

O good to hear :D as long as the TV is up and running!

grayfox

wow! good to hear, keep us posted!
Hopefully someone will find this post on this forum on Google and come to you for help :)

Have Fun!

grayfox

Hmm, you mentioned you contacted Samsung parts? I am sure they would have no trouble emailing you a PDF or at least helping you out through the phone to guide you towards the lamp....

grayfox

I am having a hard time finding those parts :( I know Samsung uses BP-XXX XXX for their part number so that would be it...

grayfox

Hello,
Lets start by some basic questions, how long have you had the tv? when was the last time you replaced the lamp? and are there any strange noises coming from the TV?

grayfox

I am sorry I cannot see your comment on my quote :P

grayfox

hello chris, sorry your post was a little confusing :D but to answer your question, yes, the sound and discoloration is 90% of the times associated with a colorwheel issue. and the part below the lamp is called a BALLAST, unless I am mistaken, I am sorry If I am, I am just trying to help ;) in order...

grayfox

welcome!!! :D

grayfox

dido! :mrgreen:

grayfox

colorwheel... :mrgreen: BTW congrats on the baby!!!

grayfox

Yes sir the reason we try this out is because everything runs through an analog input board, and if all else fails this can possibly be your DMD board.

grayfox

OK so judging by your symptoms this is most likely a ballast issue since the problem lies in the ignition (for which this takes 15kv, and the ballast that powers this is also a consumable part) but I would still begin with a basic physical lamp inspection and look for any signs of burning or fogging..

grayfox

Hi!
well to start trouble shooting, have you replaced the lamp recently?

grayfox

hello,
the lamp BP96 numbers are just for the plastic enclosure molding surrounding the lamp. The Philips lamps inside are the same ignition, watts and arch gap so they are IDENTICAL :)

grayfox

hmmm, I think you mean the Ballast and you can find nothing but original OEM parts at

http://www.discount-merchant.com/Search ... =hlr6768wx

Hope this helps!!!

grayfox

Hello!
Since the lamp is fairly new I would take a ook into the ballast, maybe noticing if there is any clicking or buzzing sounds during ignition, use or when it blacks out...
hope this helps

grayfox

Hello, normally I would mark this down as a DMD issue and replace the light engine, but you mention you have done this? have you tried both the new and old DMD board? (assembled to the engine itself)??? If that still doesn't solve your problem I would try another DMD board/light engine ... hope this...

grayfox

HEllo, sorry to hear that! :x this is a difficult part to find you might want to try getting a full cable set, but even then that will not guarantee it will come with the ribbon... you can try calling and asking, see below. http://www.discount-merchant.com/1070973-KDS-R50XBR1-p/1070973.htm hope this...

grayfox

Hello, you got me confused, maybe you mean a DMD board?! An Optical Block is used in LCD RPTVs and a Light Engine is used in DLP RPTVs, they are the same part yet one uses DLP micro mirror technology and the other LCD 3 color chip-set technology.. I think this TV is a DLP so you are looking at a DMD...

grayfox

Hello! Good and Bad news, the bad news is that these parts are rare and you will have to remove the original to get a part number since LG/Zenith and other share part providers... The GOOD news is that after you get that part number you will have an easier time because of multimple sets that use the...

grayfox

this can be caused by the video signal output by the DMD board or a video board, hard to diagnose, but you can try to find out which of the the digital video board /analog input board is bad if you test digital versus analog inputs (i.e. HDMI versus coaxial) and if the analog coaxial shows disruptio...

grayfox

Hello,
The blinking red light means it is going into "protect mode" basically meaning there's a short somewhere or a blown capacitor. This board needs to be repaired but more effectively replaced! :?
hope this helps!

grayfox

true it is sorry i did not read the topic :oops:
this sound distortions can be coming from the input board or the DMD board... let me do some research! :?:

grayfox

Hello, wow, so you got no distortion before the TV went straight to the 3 blinking dots? and you replaced the LCD optical block? If so this can be a simple issue with the Colorwheel or Ballast, depending on the reasons this is not booting up (any grinding bearing sounds would be the colorwheel, and ...

grayfox

welcome!!!

grayfox

it should i mean i use samsungparts to find part numbers they suggest for specific tvs and then buy it elsewhere ;)
kinda like you're :twisted: going to do!

grayfox

yup that would be the ballast, after your attachments i am leaning more and more towards this being your problem..
try ordering it from a place with a more flexible return policy ;)

grayfox

In my previous experiences no, you should be fine, but in theory, other component input will start failing with time :|

grayfox

yeah, I would start with the lamp! ;)

grayfox

dont get me started on Samsung flowcharts and their parts! :lol:
but yeah sometimes its frustrating, especially when I can be of no further help, but its a shame to see a big screen HDTV go to waste :oops:

grayfox

hello, :lol:
:!: actually the ballast can be defective and only give off one click, or many, or a whole buzzing sound! so I would not discard the ballast as an issue. First how long has it been since you changed the lamp???

grayfox

hello,
I am almost sure you have a colorwheel issue, as long as the image has no distortion and the discoloration is only affecting the color themselves!

grayfox

Hello,
I'm afraid it is highly unlikely that settings can cause disruption on a single input.. I think it may be time to replace the analog input board on your TV, it is relatively inexpensive and easy, plug and play, nothing to cut or solder, just a bunch of screws! =)

grayfox

Hello, well it sounds to me like you might have an issue with your colorwheel. I think it shattered or one of the color slides fell off... again I am just brainstorming but i think if you open up your tv and take a look at your colorwheel it might be physically damaged (this is not unheard of...) Be...

grayfox

I understand, it is really hard to diagnose a TV, especially through a forum, but the fact that the bearing sounds at all, tell me the cycles are off, so It is going to need replacement either way, as a technician, this would be my first approach, and it less expensive than changing a lamp I know yo...

grayfox

before you do so, do you get any distortion on your screen, or does your tv fail to follow remote or set commands?
