Sony Portable TV KV-9PT60 long time to warm up and show picture
 

Hi All,

I Have a 9" portable ac/dc Sony KV-9PT60 which has been taking longer
and longer to first display the picture when turned on. For the last
year it was taking about 15 seconds (acceptable), but just now has
started taking 30 minutes. The sound comes on instantly, and picture
when it does show (after warming up presumably) is perfect. Turn it
off after warming, and it comes on almost instantly. It is used on AC
at room temperature.

Any help is greatly appreciated.

Ok First pull the cabinet apart get out that
DVM and start doing some tests,
also check the filters in the SMPS section.
Not to mention bad solder connections.

Check in the power supply section, and in the horizontal scan amplifier
section for capacitors going high in ESR. This is a known issue in these
sets.
