Re: i have an LT170 proj. i bought on line but it has no...
You are looking at two hurdles here: 1) The lumen output of an LED light is nowhere even close to the output of a high voltage lamp in a LCD projector. 2) The color temperature of the LEDs, even if they were bright enough, will likely not match that of the lamp. This means the colors will not display correctly.
While it is a very ambitious project, I think you may be better off replacing the lamp with the proper model.

Many LED TVs and other electronics have bad capacitors on their power supply boards. You can visually inspect them by opening the TV and looking for capacitors with bulging tops. If you see any, replace them all in the power board section. Check to see if your TV is still under warranty first though.

be sure and reset the lamp hours. Flash the software if you can. These are also notorious for the ballast cable on the inside of the lamp housing backing out when a lamp is removed or replaced. If you have the cover off push the cables back into place and hold them there as you install the lamp. Also look directely at your lamp in the center and move it side to side and up and down. If there are any cracks or frosty looking spots or bubbles in the mirror of the lamp that are visible, then the lamp is probably shot. If all this fails, most likely it is the power supply, or the lamp door has gotten mishapen from heat and the actuator on the lamp door isn't making full contact with the safety swith.
1 Turn off the projector and unplug the power cord. 2 Wait 60 minutes to allow the projector to cool thoroughly. 3 Turn the projector upside down on a soft cloth so that the lamp door is facing you. 4 Slide the lamp door off. WARNING: Be extremely careful when removing the lamp housing. In the unlikely event that the bulb ruptures, small glass fragments may be generated. The lamp housing is designed to contain these fragments, but use caution when removing the lamp housing. Before replacing the lamp, clean the lamp compartment and dispose of cleaning materials. Wash hands after lamp replacement. Hg ? Lamp contains mercury. Manage in accordance with local disposal laws. 5 Detach the lamp connector from the projector by depressing the locking tab on the connector and lightly pulling it free. 6 Loosen the captive screw that attaches the lamp housing to the projector.Carefully remove the lamp housing. Dispose of the lamp in an environmentally proper manner. 7 Install the new lamp housing and tighten the screw. 8 Re-attach the lamp connector to the projector. The locking tab should engage when the connector is fully plugged in. 9 Replace the lamp door by sliding it into place. Be sure the lamp connector wires are not in the way. 10 Plug in the power cord and press the Power button to turn the projector back on. 11To reset the lamp hour timer, navigate to the Settings>Service menu and select Reset Lamp Hours.
On this model Sony the lamp access is located to the side of the set. You will see a small hook you can push down with you finger releasing the lamp outer cover. There might also be 1 screw to remove the panel.
Now you will see the lamp inner cover. It has a grey handle in the middle of it - to dark to see down there, get a flash light. Remove this by turning it counter clock wise. Now pull the cover out. Note the chip on the one corner of the cover. It can only fit back the same way.
Now you will find a slot you can fit your finger into. Pull this down and pull the old globe out.
FYI - If the globe has burnt leaving a white discharge behind inside the globe - great, your TV is healthy. If it blew with a black discharge I would suggest you take a hear dryer on cold setting and blown as much dirt from inside the globe cavity as possible. also try not to switch your TV on and off to often. If you leave the room and you know you will be back within a hour, leave the set on. You will much easier reach 8000 hours of globe life. 8000 Hours is possible, I have seen it before.
Now place the new globe into the socket. Just push it in until you feel the locking mechanism engage. Return the inner lamp cover. Turn the grey lever clockwise.
Now all that is left is to clip the outside cover into place. Put the screw back if there was one.
If you have to remove more than 1 screw - you have gone too far.
P.S There are certain lamps that does not have a clip, but rather a HEX key screw. You will receive this hex key if you bought a genuine Sony globe in the box.
The answer is yes and no. Typically OEM compatible or OEM equivalent lamps last as long as the original, but you have to remember that since it isn't the XL2100u that it's not guaranteed to work the way the OEM lamp does.
Every reseller doesn't use the same specs when they put the lamp and housing together, some of the bulbs aren't always going to be up to the specifications of the OEM, but it will fit in and work.
The best tip I can suggest is to buy a lamp from a store with good warranty, so if something does happen after you bought it, you have some recourse.
According to Epson the led will flash red in one of two cases:
Flashes red with 1 sec intervals - either the lump has burned out(We can rule this one in this case) or the lamps cover is open (try checking the cover's sensor)
Flashes red with 2 sec intervals - an internal problem, I'd suggest contacting Epson's support.
