    Thanks for the response, that's led light status indicated of "waiting to re-light the lamp".



    It seems that the problem is still in the lamp. You must double check the lamp connection. Ensure that the lamp is securely connected to the ballast board connectors and properly seat-in to the lamp housing. Ensure also that the screws are installed securely or otherwise the symptoms will remain. Reattach the lamp unit door, making sure to insert the hooks on the left side of the door inside the opening in the TV cabinet. Make sure that the lamp unit door is installed securely.



    Please double checked the above mentioned, re-installed the lamp if necessary.



    Hope I helped you.



    Have a nice day!



    Thanks for using Fixya.

    blue solid led light, yellow blinking lamp light indicated that the lamp didn't initialize and re-start the process. If you've confirmed that the lamp is securely seat-in and checked the surroundings, another caused of this symptoms is the faulty ballast board and its power supply. Checked if you can hear the ballast board trying to ignite or not upon powering on the unit and cycling from on and off.

Hi, Please make sure lamp cover has been placed back in properly because it has to engage a safety micro switch inside that prevent tv to turn On.
Lamp cover is first thing that was removed to access / replace lamp in dlp tv.
If that does not help then ballast supply could be another reason of no lamp fire up problem and swapping ballast supply in/ from similar working tv will confirm it.
Hope this will help.
Thanks.

My power blinked and now my tv wont come back on,the yellow light just blinks and it wont do anything else???


not the lamp and lamp door is closed--double check lamp to make sure it is not shattered inside and is correctly inserted.

Other than that the possible reasons are Bad ballast that fires lamp, power supply board problems in the set or even a bad optical light engine or fan or fans not running.

I have a toshiba 65hm167 no red color on the screen


Your TV is a DLP one lamp does it all, not like the old projection TVs with the Red, Green & Blue CRTs. Your TV may have a bad light engine or lose cable connections.

Good luck

Samsung 50" DLP - Lamp Light Blinking after bulb replacement


Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.

Samsung HL-R6768W started making squeal noise from rear of TV. At same time lost picture and will not come back on. Sound is ok and you can hear light trying to turn on. Can fan motor not working correctly...


Look at the fan and verify its comming from the fan and not the power supply unit, you can clean the fan or replace it, but yes the fan would be likly the problem. Make sure you double check the power supply unit and clean if its needed,

Toshiba 52HM84 DLP TV with new bulb but the lights keep blinking


They exact way the lights blink are telling you what the failure is. If the tv is firing the lamp and the lamp is bad, you will hear a buzz sound for about 1 second. The tv tries 8 times before it gives up and spits out the lamp error. Check the user manual for led diagnostics. If you put in a new lamp but still have issues, you've likely got a bad ballast (most common on this model) or colorwheel (less common). Both are part of the optical block (light engine) and I don't believe they're available as individual components from toshiba.

Samsung DLP HLM-617W/XAA


with lamp out (door closed) the ballast should "strike" or give an arc sound, trying to fire the lamp. If it does not do that maybe the color wheel is not spinning up - has to do that first.........then the set will try to fire the lamp
