Finlux ns55as crt tv

[tendi]

Hello every one. Can somebody upload for me the service manual for this Finnish television? The tv runs for 3 minutes and cuts off the picture but the sound remains. The channel number stays displayed as if the tv is normal. The tv involves a number of I.C's which are "Bus" controlled via I²C. At least does anyone have a clue? Thanks...

P/S Some of the i.c's: TDA 9330H, P87C51SBBB, TDA8840, M30620ASF...

You can buy the manual direct from Finlux through their web site.

This might be heat related. Freeze spray may locate the faulty component.

Finger on epoxy chips to check hotspots and look for bulged cap lids.. Seems like a power thermal issue.
