Power supply problem

I have the same problem everyone else has. Turn on, green light comes on for a second, then goes red. I am an electronics tech for Texas Inst., so I can replace components myself. Is there a specific component that is the problem with this supply? Any help would be appreciated. Thanks,Frank                           f-haley@ti.com

There are 3 capacitors that become defective all the time, the values are 1000uF/16 volts and they are located in between two heatsinks on the secondary side of the power supply. You should also remove HS4 to check 2 other capacitors that could become defective as well, their values are 220uF/25 volts.
Let me know if you need further assistance.

    The reference designators for the defective capacitors are EC18, EC19 and EC20 (1000uF/16V) and EC12, EC15 (220uF/25V).

My protron pltv-37c will turn on for 10 seconds the light turns green then goes to red after ten seconds


The green light indicates power is being applied. The change from green to red indicates that the power supply has failed

Hitachi Model 50DX20B No Sound or picture


GOOD question and well asked----Start at the beginning.

if light on main fuse is good---do you hear the power relay click on and off?

These sets for trouble shooting use a number of green and one red LED inside on the board--the red one should be on when power is connected and the others at turn on all should light--if do this with back off look for the Green ones---when set turned on do all light and then go out--look for one that goes out first or last---each is connected to a specific voltage coming out of the power supply---they will lead you to the area where the trouble is---this set is old enough you may be able to find a service manual online.

I have fixed a lot--going to need a volt/ohm meter for any real tests.

I am ready to help if you need it.

Replaced bulb yesterday worked fine. Today light will not turn on. projector turns on both lights green for 10 seconds, then power goes red and status blinks green for about 5 seconds, then status light...


green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit
