hmm, I still think you should try the colorwheel, any sound emitting from the bearing (even if its just when its winding down) means the bearing has reached the end of its lifetime...

grayfox

hello,
if you can get the transformers, there is still a chance this might not fix the problem, I would settle for exchanging the ballast altogether..

grayfox

Did you install the new lamp in? if so then this might be a ballast issue.

grayfox

hello,
99% of the time these symptoms are caused by a ballast (if you have a new lamp in your tv).
If your lamp has been in your tv for around a year or it seems burnt, fogged or damaged, this might eb eindicating you need a new lamp.
hope this helps!

grayfox

hello,
hhmmm this is a tough one... have you tried looking into the digital video board? did you try both digital and analog inputs?
I would have gone your way and replaced the dmd/light engine too!

grayfox

if the colors are off your jumper either needs to be set or removed, (a jumper is basically a plug with conducting material like metal or copper) that establishes connection between to pins.

grayfox

Hello,
in any other case I would advice changing the lamp first but since you mention it wants to power up and fails, then you can hear the bearing, I think the colorwheel is bad and needs replacing. I am almost sure the colorwheel is preventing the tv to boot up.
hope this helps.

grayfox

Hello,
If you have not changed you lamp in some time, this is most likely the lamp, however if there is a new lamp I am almost certain this is the ballast given the symptoms you describe..
hope this helps!

grayfox

hello, If the lamp is new and of brand (Philips or Osram) then I would suggest changing your ballast next, given the symptoms you describe, It is easy to do (you can find videos on youtube.com) and the part is relatively inexpensive http://www.discount-merchant.com/Mitsubishi-Lamp-Driver-Ballast-938...

grayfox

=) thank you for sharing your story! I keep telling my friends who also spent thousands of dollars on an HDTV that spending 200t o 300$ to save it is completely worth it! you are proof. Also I purchased a non working 60 inch from craigslist for 150$ and fixed it with a new lamp and ballast 200$ so t...

grayfox

Hello, Do not worry about the wires and connector, this is an A/C (alternating current) lamp so there is no polarity. as long as you have the correct lamp and it is of brand name (Philips or Osram) you should be fine. This might be an issue with your ballast. Have you reset the lamp hour timer if yo...

grayfox

hello, if only the colors are moving around this can be a simple colorwheel replacement, if the image itself is distorting then it might be a DMD board issue... Once you start getting the malfunction does the image itself stay clear but the color vary? or does the complete screen go into what you de...

grayfox

this is most likely a colorwheel issue, do you have any images?

grayfox

Hello,
good news is since there is no image distortion you can narrow this down to a ballast or lamp, and since it has been a while im thinking theres a 90% chance this is just a lamp issue, but with another 2 or 3 lamps changes it will need a ballast change..
Hope this helps

grayfox

good for you! =) however keep an eye out for flickers on the screen or sudden dimness which would indicate a weak ballast +) glad to hear your tv is up and running

grayfox

hello jimmy,
I agree, it might be a bit of both. If the lamp has not been changed in over a year I'm thinking its most likely the lamp, however if you recently replaced the lamp with an original lamp, judging by the spark on the ballast, I think it might be time to change your ballast.

grayfox

hmm let me do some research..

grayfox

I think you just gave me the answer! now do you know if the MAIN (one coming from the street) signal coaxial cable is shared amongst the 3 HDTVs???

grayfox

:D I want to say, taking apart the front and looking to see if the buttons and IR sensor are on the same Part/Board. If they are separate then I am leaning more towards the DMD board.

grayfox

so you have a new lamp, screen flickers and there's some discoloration? I think this might then be an issue with your colorwheel. if you still want to take a look at the ballast, here is a link below! http://www.discount-merchant.com/RCA-Lamp-Driver-Ballast-261629-p/sku9513-rca-261629.htm Hope this ...

grayfox

I hope that did it, maybe it was referring to initialize the timer... I am not very familiar with Zenith / LG service menus... and the ballast is what powers up the lamp, its a small 3 by 6 inch board that plugs directly into the lamp , easy to instal ;) take a look, all plug and play http://www.fix...

grayfox

hello,
you are correct this can be a power supply or ballast issue, but if you have not changed the lamp in a while, this might just be a lamp failure, how long has it been since you have replace3d the lamp?

grayfox

I could not find this lens sold apart from a light engine =( do you have a part number off the light engine? I have a lot of friends with service centers and I can maybe track this part down! If I can't i saw some light engines for around 300$ I think its a good price to pay to save a 60 inch HDTV.....

grayfox

Hello, this can be a simple input problem, if the buttons on the front are part of the board with the IR sensor for the remote (about 14 to 25$). If this is not the case, it can be a DMD (motherboard of a dlp) board issue, in which case you would need to swap out the complete light engine (around 20...

grayfox

The color wheel yes, it ranges online from 60 to 80$... now the DMD board is a little more pricey since it comes with the complete light engine but I would still say it is worth it since for those 200- 300$ you can save a HDTV that one day cost thousands...

grayfox

I think its a problem with the feed, do you get this on any other set?

grayfox

this can be one of two , digital video board or DMD board, I am leaning more towards the DMD board... have you tried digital vx analog inputs? (i.e. HDMI vs coaxial)

grayfox

I have seen this before when even after manually resetting the time meter it keep prompting! what I did was unplug my tv overnight and next morning it was gone, I have no idea if it will work for you, if it does not, I have to assume your TV has a weak ballast and its better to replace it now that y...

grayfox

Hello! Are the dots uniform in any way? I do not think there is any way a lamp can cause this kind of distortion on your screen, this is most likely a DMD issue.. They are usually sold in complete light engines, and very easy to slide in / out... If you have any images I can help troubleshoot furthe...

grayfox

Hello Chaiyz, I am sorry none of our fellow members have not gotten to your most recent question. This is a fairly common issue with Sony KDF models, and it usually indicates a wear on one of the 3 (RGB) LCD chips, in which case you would have to exchange the complete optical block... like the one b...

grayfox

Hello, I think maybe the lamp you are trying to remove was forced in, I do not think you need to remove the plugs in order to remove the housing from the TV, do you have any images? also I know the forum moderators post videos on youtube yet I could not find one with you model number, do you have an...

grayfox

Hello,
I think maybe the lamp you are trying to remove was forced in, do you have any images?
also I know the forum moderators post videos on youtube yet I could not find one with you model number, do you have any other lamp number???

hopefully I can help you further =)

grayfox

Hello, great find! has the TV ever turned on? do you know if the previous owner changed the lamp recently or what troubles they had with it? If the TV just went out I would suggest putting in a new lamp and ballast since these are the two most common problems with RPTVs. I would probably begin with ...

grayfox

Hello,
That can be one of three things, Colorwheel, Ballast or maybe even a Cooling Fan.
If it is more of an electronic arcing sound it can be the ballast, If it is more of a mechanical grinding humming or even screeching sound this would be your colorwheel...

grayfox

Hello, most likely your input board is malfunctioning, is the HDMI input the only one that does not work? was the same HDMI cable used in your LCD and DLP? I had an issue with a cable once were the connectors were damaged and I was running in circles until I figured out the cable was damaged!!! Do n...

grayfox

hhmm... do you have any images of the distortion?

grayfox

Hello,
every part in you DLP is replaceable do you have any images you can post? I think there might be some damage to the DMD board, but a more detail description / pictures fo the cistortion could help me diagnose it properly...

grayfox

Hello, The link you provide is exactly the lamp you need, but it is for a bare lamp, (some assembly required). If you want to simply swap enclosures (out with the old in with the new) I suggest the second option, I assume you get the same as below. http://www.discount-merchant.com/Samsung-BP96-00826...

this was replied to in the link. :P

According to samsungparts that is the only revision out for your TV :oops: http://www.samsungparts.com/Products/Parts_and_Accessories/HL61A650C1F/Default.aspx and I cannot seem to find any compatible model, Ill go ahead and place a "email me when it is back in stock" request see if anythin...

grayfox

Hello! I do not think this is a problem that can be fixed within the service manual, this is most likely an issue with your optical block, maybe one of the LCD chips is burned out... Its an easy swap out no cutting/sodering required just a bunch of screws and plugs, this is what it looks like http:/...

grayfox

Did you recently replace the lamp? now before the tv shuts off, is there any distortion or discoloration on your screen? if not and you have a new lamp then this is most likely just a ballast issue and an easy/cheap fix. if not then I would recommend changing the lamp first...

grayfox

I think it is time to change your DMD board, moisture in an RPTV screen would have to be sufficient to drain down, i do not think wiping it down would cause this. The trick here is that you might have to replace the entire light engine since the DMD board is usually harness to and sold as a unit... ...

grayfox

hmmm tough one, so no distortion or discoloration before it shut down, it just wont turn back on? I think it might be the main power supply board...

grayfox

Hello, the cheapest way to diagnose the problem would be to order and change the temp sensor (see below) since it will be cheaper than having someone come to your house to take a look at the set! http://www.discount-merchant.com/SearchResults.asp?Search=samsung+temp If this does not solve the proble...

grayfox

Hello, When you start getting the distortion on your screen, have you tried out if the PIP option is affected as well? The image distortion is notoriously caused by a digital video board, unless you test digital versus analog inputs and the results vary. If your set is sometimes not accepting comman...

grayfox

Hello, You might find it useful to know that the lamp ranges (if this is a philips lamp) ranges from 100-120 even if it states only one of the two values. I think it might be time to replace your ballast, this is the second most common problem with RPTVs and it is one of the consumable parts that ne...

grayfox

have you taken a physical look at the lamp? If there is no fogging or burnt parts, the lamp is probably fine and you might be having a ballast issue...

grayfox

hello,
normally i would have suggested what you just mentioned! but heres another option, tell me if it works!
(note* you are to hold the + and 0 at the same time!)

Hope you had happy holidays also! Sorry for the late reply, Mitsubishi and Samsung forums are always swamped! i am sorry to hear about the HDMI incident, but luckily this input board is easy to replace and very economical. You will need to remove the back shell (about 8 screws) and unplug every ribb...
