Re: lamp replacement

Well I don't know if I should be answer this question, it's going to cost you,
Oh heck there you go , of course you can, it is so easy, even my two year old can do it.
Here something you should know first, don't tough the bulb, do you know what I'm saying don't touch it,
Make shure that both fan's or working, this is one issue that if the fan is burt out, the bulb won't last, the second problem when bulb burn's out is bad ballace, because of bad cap and diode inside, but don't worry about that,
Here is the info on other adjustment you can do but don't read to mutch, you'll get lost t
Mmmmm did I mention your welcome

What about Bob

Replacing Light bulb w/housing

Lamp is replaced by customer in most cases---look to owner manual---in general if lamp up front (I think yours is by the model number indicated) the front plate beneath the screen gets removed (have set unplugged) and a lamp door is marked---it opens when screw/s securing it are removed.

Inside are two more screws---with them removed grasp the handle for the cartridge with the lamp and pull it out.

Be sure to get a Mitsubishi lamp and not a generic "bulb" which would require you to take the housing apart---generic bulbs have a much shorter life.

carefully slide the replacement in so the two pins on the rear connect correctly into the socket in the set where they go.

there are video instructions for many sets on You Tube.

I replaced the bulb because it was broken now when i put the new one in the the power stand by light blinks 3 times repeatly and then goes solid red

Did you just replace the bulb or yjr whole lamp assembly? There is only one correct way to put it together in a new housing. If it's wrong, it will not work. Also, make sure the safety latch on the lamp door is back on securely as well.
Three flashes is Lamp door not detected. Hope this helps

Sony kds-60a2020 lamp problem

I would change the whole LAMP ASSEMBLY because if you touch the lamp while changing it out of the housing the oils on your hands will cause premature failure.Most of the time the lamp assembly's come with replacement instructions but yours is not too bad it is located on the left hand side if looking from behind set.

Power light blinking and housing for lamp screws broken

I bet the area around the lamp shows signs of warping and/or cracking too? This is a VERY common issue as the fan that sits above the lamp gets clogged with dirt which allows the lamp to over heat which decreases the lamp life as well as distort the plastic casing around the lamp. The fix is a thermal fuse kit and a new fan and of course a good cleaning of the other fans in these TV's. This should be performed by a service technician.

Lamp light is lit and TV won't come on

Change the whole housing, if you touch the lamp with your bare hands oil is deposited on it and it will cause premature failure. If the lamp light is lit it is a good bet the lamp needs to be replaced.

Samsung 50" DLP - Lamp Light Blinking after bulb replacement

Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.

Is the color wheel fine if it is spinning? Can you see any light from the dlp lamp when the screen is off? I had a service guy come by to fix my dlp and he replaced the bulb with no luck. He said it was...

First You can look on the rear of the set and see the lamp light shine through the lamp door vents when the set is on. Second you need to replace the whole color wheel before the set will work. Third Color wheels may spin but not at the correct rpm and may shut down the tv and sometimes color wheels will emit a high pitched whine or buzzing sound indicating that the bearings in the motor are wearing out. But now that you have to replace the color wheel you will need to adjust the index delay in the service menu. I suggest having a factory trained tech repair the set.

PT43LC14 Bulb Replacement

Long screwdriver? maybe if you consider about 3" being long (explains why wifes upset). I have replaced the bulb only and the housing with bulb several times with this pos tv. The housing and bulb is one philips screw behind the front snap off panel (the big front piece that has the hdtv stamp in bottom right corner, just pull out it has push in plastic stubs) then remove the philips screw next to the big white warning label where there is a small half circle cutout around it in the label. then one screw on the big black piece of plastic with a fold down metal handle. Then just pull strait out, little snug but as long as you loosen the screw it should slide right out. to replace just slide in whole housing replacement and tighten the 2 screws back up. As for just replacing the bulb, I buy mine off ebay and they have all come with real ez instructions. I believe there is 2 screws holding the clip for the 2 wires coming off the housing, just take that out as the new one comes with wires. you just screw on the 2 wires to new bulb tighten down the wire clip and put it back together. The housing can be just pried open with a flat head screwdriver (think there was a couple tack welds) then after new bulbs in just bend back in as much as you can, it will clear in the tv and be fine so it doesnt need to be exact. Hope this helps and if anyone wants another one of these tv's you can have mine!
