The ballast is actually a switch mode power supply that powers the lamp. It is an
integral part of the light engine and is not replaceable. The light engine has a price
tag of $950. If you replaced the lamp with an after market one and not the Toshiba
lamp you can experience the same problem. Some of the after market lamps will
not fire at the same voltage as the Toshiba. The blue led will come on solid and the
yellow blinking. It will try to start 8 times then give up.

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.

I have a building full of 427G lights with 12-15 that won't work, but appear to have good bulbs. What is the issue?


Florecent or the yellow HPS bulbs? If HPS you have a bad bulb, or bad ballast. May be similar issues if florecent.

Service man says light engine. how much? jvc model hd52g886


Whites are yellow can be a convergence or color balance problem, and lamp going out could also be a bad ballast board, black spots are usually light engine, could be a different fault on DMD board.

The fact is that when you get all this symptom together unavoidably you have a faulty light engine.

The light engine is the most expensive part to replace, its price for this model is always over $1600 ( I know, keep the heart tablets at hand).

Here is the part for your model: TS-COP7A-SAA-R

Turning off


Three blinking lights indicates a lamp problem.  This can be from A) a bad lamp, B) bad ballast C) bad Light Engine/DMD Board.  Try replacing the bulb first.  As with any lamps, it has a limited life.  If that doesn't work, you can try the ballast next.  If that doesn't work, it's time to take it in to a certified repair center for diagnostics.  Here is a page from the service manual on the three blinking lights.

TV WONT TURN ON. BLUE LIGHT GOES ON THEN THE TWO RED LIGHTS BLINK IT HAD BEEN WORKING THEN ONE DAY IT JUST WONT TURN ON.


I'm going throught the exact same thing right now. After the lights quit blinking, and the blue light goes off, does the red lamp light stay on. This usually means your lamp has gone bad ($200.00 plus). But when I ordered the lamp, it did the same thing. Had to have the certified hitachi repair man come out for the and told me it had to be a bad lamp, so I ordered a 2nd one with the same result. He came out again and had to take the TV away, later telling me the ballast must have blown when the original lamp went bad. Another $200.00 part. I haven't fought this one with Hitachi yet but am going to try. The ballast shouldn'e go just because the lamp goes out. The set is only 21/2 years old and I've already had to spend about $700.00 on the light enging replacement and now this lamp and ballast expense. Love the TV but would expect a lot less problems from a $2500.00 top model Hitachi. I'm going to see if they feel the same way, hopefully not but I'm not real optimistic they will care. Hope this helps.
