when you changed the lamp, did you blow the dust out of the projector? if the screen on the side of the lamp is blocked (i.e. with dust), the lamp will blow quickly. if the projector were to overheat, by the fans not running or blocked vents, everything would shut down and the led would blink red.
I think it's the bulb, the best would be to take it to the shop where you bought it - or any other good electronic goods shop - so they can test it. If its still under guarantee its better to take it to the dealer. Mine had to have the bulb replaced after only 8 months, but it was still under guarantee.
I had the same problem after purchasing a new bulb. My husband pulled it out after it would not fire up and the new bulb plug in conecter (white with 4 holes with two wires) was different. Take your old bulb and compair the two conecters and see if they match, then check if the wires are in the same slots as in first and last. Mine on the new one were in the first and second to last slot. So we took the wire out of the second to last and put it in the last slot and installed it and it fixed the problem. We also had to unplug and replug it in and do a master reset by pressing the Power and Channel buttons and the same time for 15sec. Hope this helps.
Well a single red blinking means the lamp won't strike after five (5) attempts. The "squeaking" sound if it's coming form the large fan usually always means the Mos-Fet fan speed controller chip has failed which presents sometimes as an intermittent squeaking sound. Which would implies the lamp may have failed from the resultant over temp. However if the squeaking noise is coming from the color wheel that would mean it's bearings have failed and if is is unable to phase lock at reference speed the lamp would also not strike. The odd symptom is the remote thing... That does not fit! If is actually is related to the common cause of all the problems... That leaves only the power supply has partially failed (not too expensive) causing all of these symptoms.
I generally fix this by re-seating the bulb housing. Take it out and put it back in. Look for cracking at the base of the bulb on the mirrored surface. It could be a barely functioning bulb that isn't busted, but can't initialize. I would take it to a shop that has the same bub type in a housing and make a quick switch.
