Ok...this is only a theory. Did u replace bulb..or lamp unit?
To cut along story short the tv has a timing device in it set to about 8000 hours. When u look at a picture (google) of the new replacement lamp unit, there is an additional circuit board on the housing, this aligns to two tiny contacts inside the tv. (you can see it when u look inside the socket. its green and about 10mm by 20mm and labeled lamp saftey). this circuit board (on the lamp unit) is absent on the one that comes with a new htd501. I believe the replacement lamp housings circuit board is a 500Ma fuse, which momentarily sends a current to reset the timing device then immediately blows, leaving your timing device reset to 0hrs.
As i say this is only theory based on reading other materials online, however my friend has this problem and i am waiting for him to give me the go-ahead and try it.
What I will do is make a plasic board with bean tin contacts aligned to the contacts inside the tv, and solder a fuse housing to the home made contacts and use a 500ma fuse. this should reset the timer!!
I cannot guarantee or even recomend this unless u r sure and confident about making the above gadget. however i will return to this page and tell u if i was successful in a week or two.

    It is NOT a fuse (well... maybe a special fuse) but a resistor!
    temporarily put the specified resistor across the contacts i mentioned as per the instructions at the German site above.
    Thats what i am about to do now. Will let u know if i have success.

    OK I have done it!!!!!!!
    simply solder a resistor (value 470 Ohms) across the contacts,
    then put the bulb and housing back
    then screw the black front plate on
    switch on tv as normal
    wait for light to turn green
    switch off tv
    timer is now reset
    take all the above apart again!
    remove the resistor
    put it all back together again
    your tv is now fixed!!!!
    let me know how you got on
    ---!!!GOOD LUCK!!!---

Sagem used two methods to reset the lamp timer.

HTD501 is as described above, with a resistor.

Subsequent models have a fuse mounted in the lamp holder. Whwn the lamp is replaced the fuse should also be replaced. When you first switch on it will blow deliberatrely resetiing the counter

Should I replace my lamp for my Panasonic 1080i htd t.v. pt-50LC14

Replacing a lamp won't work. There is not even one lamp in your TV. I'm afraid the lightening has done more damage than can be repaired. Even when some tech manages to repair te error, the TV can have the next error in days or weeks.
Try reading something about ESD. Electro Static Discharge and what it does to electronics. Electrostatic discharge

No picture on a DLP when you can see the lamp is working is ALWAYS the DLP chip. BECAUSE you recently replaced the color wheel, i suspect that the LVDS/data cable to the light engine was not plugged in well and has come loose. I suggest checking and rechecking every cable and plug you can find.

Mitsubishi WD-52525 52-inch DLP HDTV ywllow warning lamp light

that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours

What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away

or just simple replace the lamp. 915P020010

Check that you replaced the lamp in the right way, and also that the unit is well reassembled, you may also need to reset lamp counter from menu on some model.
