    TV won't turn back on with a picture. Sound is good. It won't turn on the lamp, which is new.

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.

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.

Just some thoughts based on your question.

My 50HM66 did the same thing. Try putting a fan to the side of the tv so it blows cool air around the back. I also removed lamp and vaccuumed as best I could. I think this is an overheating issue with the tv.
