Television turns on with yellow blinking light then blue light but no picture

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.

the red picture is because the optical block is bad now this part cost about $500 plus labor , when you took the lamp out you need to put the door back otherways the tv wont wort

Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

Hi Genaro,

Blue led light lit solid and yellow led light flashes is an initial attempt of the set to re-light the lamp.Red led flashes and yellow led light solid means that the lamp won't light up that's why it only has sound without the picture.
Since you've replaced the lamp twice and still the symptoms persist, I suspected that the fault came from the ballast board and not on the lamp itself. If the ballast board gone to malfunction, there's no high voltage will produce to light up the lamp and will sensed by the processor and trigger the error code (Flashes/solid led light with color code).

To verify whether the ballast board is faulty or not, check if the lamp will lit by looking through the lamp door louvers at the rear of the cabinet upon turning on the set.
Please let me know what you will find to assist you further.

Can you tell me I turn the toshiba on and there is no picture but the blue and yellow light keeps blinking

I had the same problem after replacing several things and still having same problem, it ended up being a capacitor.

Most likely the lamp is dying. Try replacing the lamp before calling a repair tech. What does the Owners manual say about the blink lights?

Ur video ic inverter board is dead.
U need a new one.

Replace both of your STK ics 392-560s or 570s they maybe 392-110s if so use 392-180s call electronixs for parts 1-800-223-3205

If the picture turned yellow then that usually indicates a loss of blue. The blue CRT might have shorted out or the driver to it. The driver will be the lesser of cost in repairs.
