You have two problems -- the first is the $75 lamp that won't fit in the lamp slot.
I've seen that, and the casing is not the manufacturer's original casing -- it's generic at that price.
What do I do when I run into that? I swap the lamps in the casing. In your situation, if you could return it for a Samsung original that costs $140, it would be a better investment.
Samsung originals come in a box with the Samsung LOGO on it (usually blue and white box with the blue Samsung Oval)
Generics blow....really bad Generics don't fit. Angry owners with really bad generics usually damage the lamp plug and end up with another $200 ballast.
Not worth the $65.00 savings.....
Now the BUZZ you mention is actually WHY the lamp won't light....
You press the power button...the buzz starts within one second of pressing the power button. When it shuts down, you hear the buzz NOT STOP -- it sounds like it spins down ! That points to a BAD Color Wheel !
And if the Color wheel cannot get up to FULL SPEED, then lamp does not get the ok signal to fire !
Bad bearing in that color wheel -- needs replaced.
The part number for your color wheel is -- BP96-01103A
You can buy it here --
Both of those places sell Samsung originals, any other online store will be questionable as to whether it's generic or not.
Always phone them for that answer...
Now, I am going to build a set of dissassembly instructions for you. I'll be back
Ok, here's the disassembly instructions, they're pretty concise. The plugs to separate the chassis from the engine is the only place you need to exercise your own judgement.
Now usually there's only two problems I have seen with installing the color wheel. It can cause the TV to turn on, but the 3 lights up front will start flashing if you have these problems.
The Color wheel is cocked in the compartment and is jammed/won't spin -- simply loosen the screws holding the color wheel in the compartment and lift it up and check the rubber gasket is IN it's slots.
Check to make sure the FOIL side of the ribbon cable is pointed towards the back of the TV set , not the Front !
Either one has happened to me several times thru the years, so don't be surprised if your TV doesn't start -- that wheel MUST spin up to light the lamp.
If you have any questions, just ask
Tips are greatly appreciated !
