Some possible reasons include: New lamp is generic and or has a issue----excessive dust or dirt inside the unit on fans etc.
Some of these units had a feature in the menu for quick on where lamp is lit at low level all the time---this shortens the life of the lamp etc
If you did not have this issue before lamp replaced I would suspect a generic cheap bulb may have been used instead of the Toshiba cartridge / lamp combo which costs more.
With the quick on if the set has it normal time is 20 seconds for screen to light----set WILL DETECT IF LAMP IS NOT COMING UP FAST ENOUGH OR BRIGHT ENOUGH.
Generic lamps (cheap) will never be as bright or last a long as a OEM lamp unit.
OK. I have this same issue. I replaced my bulb a month or so ago. TV worked fine. Then one morning I turned it on and it was on for a good while, till it went to a black screen w/ sound only. Lights were going through the reboot process as designed for 8 attempts before it went to the solid red light. From the red light, if I unplug and plug back in, the tv will come on for a given amount of time, which varies, and then cut to the black screen. A repairman told me that it sounds like the digital board is bad. He wanted $150 for the board and $100 labor. I cannot find anywhere where the board would be located or where I can purchase a replacement.
Hi , make sure you put the cover back on so it can press the switch to let the tv know door has been shut and will allow to light bulb.Also when putting a new bulb in the ballast, which is the board that powers the lamp, sometimes its not able to provide enough power to light it up because it was used to provide a lesser voltage on the old lamp.Make sure you reset the lamp timer I dont know the exact code for it but u can search it on your manual.Hve a blessed weekend!
Recheck all the projection lamp conections again.Still getting,the same result.Replace the projection lamp again,some how the move,it got the projection lamp shorted.
Either you have a defective Lamp or your Ballast Board has went out It is what turns on Lamp CK out Encompass Parts Distr online type in your Model number then it should list all the Parts for your TV or Call them 1-800-638-3328 also make sure Fan to Lamp is working if it stops running Lamp will not light.
Start by replacing the bulb. If thats a no go, check the ballast. Its a small circuit board directly underneath the bulb housing and is replaceable through the bulb panel. If those two don't work, comment back and I'll walk you through more 'in depth' repairs.
