Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

4 blink is a fan error. This is caused by one of the three fans not spinning fast enough or has stopped completely. The fan that usually causes this error is the one over the bulb and toward the back of the set. The repair is not expensive, but to do the service correctly you must get all the dust out of the tv or the fan will clog up very fast again. Getting the dust out is kida tricky because you have to get the dust out without contaminating the light engine, if it gets contaminated you will get colored splotches on your picture. I recommend getting a pro to fix it, the repair should be fairly reasonable around $150 to do the repair. The fans are not that expensive.

Hi it sounds like it could be an issue with board that powers the lamp ,it's called the ballast.When you put a new lamp in the ballast has to provide more power ,when it starts to go weak it will not light up.Sometimes you can put your old lamp in and will work fine.Try partstore.com they might have it right there.Hvae a blessed one!
