problem dvd player power supply

[noobies99]

my dvd power was dead it wont start. it has no output voltage in secondary wnding of the transformer.

the power supply module uses a
philips STARplug TEA1523P

(GENERAL DESCRIPTION
The TEA152x family is a Switched Mode Power
Supply(SMPS) controllerIC that operates directly from
the rectified universal mains.It is implemented in the high
voltage EZ-HVSOI process,combined with a low voltage
BICMOS process. The device includes a high voltage
power switch and a circuit for start-up directly from the
rectified mains voltage.).


what seems to be the problem? is it the starplug or transformer?

Hi, Noobies99

welcome to the forum and happy new year2k7

attched a datasheet for the IC-- study whether this helps you

In the past I have noticed electrolytic radial capacitors getting bad and not showning the usual signs. Particularly at the control function components. They are generally voltage undersized.  Just a thought. Hope it gives you proper direction.
