HLP5674 power off after a few minutes

1st odd thing i noticed is i have to hold the power button for a few sec to turn on.

after a few 2 seconds i get good clear image, and the fan at the back is running well.



then it does a cold shut down, fan and all turns off.



i get the lamp and standby/temp led on the front flashing on and off together every 8 seconds.



if i unplug the power cord and plug it back i can turn the tv back on.



then the issues repeats.



thanks in advance for any help

Hello,



Please advise if you have replaced the lamp before. If so how long ago ? Also check to see if you hear any sounds like buzzing or humming coming from the TV. Please also advise as to how old the TV is. We'll be looking out for your reply so that we can try to pinpoint the problem.



Regards,

i don't hear any odd noises, i believe this is the 3 rd bulb.

i replaced a color wheel a while back.

the last bulb is a few years old now but the tv does not get used as much anymore. maybe few times a month.



after looking closely at the bulb there is a clear glass stem, about half why up there is a bulge. half of the bulge frosty white in color with very small hairline like cracks in it. It seem it may be a bulb issue. i am guessing after it heats up the expansion causes it to fail and shuts the tv off with a lamp error, once the tv cools down the process repeats.

i get a good picture and then it shuts off after a minute or 2.
