I will recommend to take the lamp out and slide in again, it might be that your TV havent detect that there is a new lamp. By doing this you will reset the lamp timer. If dont work search in your manual how to reset the lamp timer.

SOURCE: TV doesn't turn on

You really should give make & model number when posting, it helps us immensely, your lamp and possibly the ballast is bad, start with a new lamp first, odds are very good that it will fix your problem, can`t help more without manufacturer and model number, good luck, ps, order the original lamp, generics are junk and a waste of your money.

How do i determine if my ballast board or capacitor is bad in my toshiba hd tv model no 57HM167?


The chances of the ballast failing are small on this model. Count how many times the Yellow light flashes before it pauses. Then google 57HM167 and the amount of blinks. ie " 57HM167 Yellow light flashes 3 times" That will tell you what you need to know. You can also post it here and we can help. I suspect you have a stuck fan(the fans are monitored to see if they are spinning. If not, they will not allow the TV to start up). Or you have the cover for the lamp not installed all the way. There is a switch that the lamp cover activates and the the TV will not turn on without it secured.

Replaced dlp chip


Kelly,

The yellow blinking light generally means that the lamp cover is open. You may have accidentally jarred the lamp while changing the DMD chip, and the lamp safety switch is not engaging. The first thing I would try would be to re-install the lamp and make sure the cover is on correctly. Let us know if that solves the problems. Thanks.

Toshiba 56hm66, lamp replaced but lights still blink


Check the circuit boards to see if any have failed. They are small cylindrical objects. If the tops of any of these are bulged instead of flat then they are bad and board will have to be replaced. Hope this helps.

Make sure lamp cover is also fixed on tv cabinet after lamp installation.
If lamp cover has not been put on its place, tv wont turn On due to safety switch inside that place that gets press with lamp cover.
Thanks.

Just changed the lamp and the "status" light is


you must install the lamp door after lamp replacement to get the "yellow" blinking to stop. if the status is blinking red then you may be having a fan failure internal to the tv. also make sure that the side filter door is installed and secure

I have an LG DLP. that turns off after 15 -30 seconds


If the second light is blinking to orange or red, that is usually the lamp indicator light on an LG DLP tv. That indicates your bulb needs replaced, or something surrounding the bulb has failed (like the cooling fan for the bulb for example) IF you have a spare bulb handy, I'd replace the bulb, keeping in mind if you touch any part of a new bulb with your bare hands, you just cut the life of the bulb by more then half.

TV was working earlier, today came home no green power light no nothing


I looked up the manual online - after you replace the bulb, you need to reset the bulb life timer. Using the TV remote push the menu button, SETUP menu, select the lamp reminder option to reset the hours to zero. That might help the status indicators.
