SANITAS SBM 09 Csuklós vérnyomásmérő bekapcsolás után hibakódot ad (EP)
Sziasztok! Egy ismerösöm adta a fenti vérnyomásmérőt, hogy bekapcsolás után nem hajlandó semmit csinálni. A kijelzőn az EP felirat jelenik meg, és nem hajlandó elindítani a mérést a masina. Én valami hibakódnak gondolom az EP-t, de nem találok semmit erről a neten. Lenne esetleg valakinek valmi ötlete? Köszönettel: gapati

Intech LH-5 Heater

Company no longer in business here in the US.
This is a product that heats up and dries wet ski boots,
the board powers 2 big heat guns I guess with programmed cycle
times. No SM or schematic of course.

Main bridge was shorted, seems directly fed from 115V line power.
Replaced the bridge with a thru hole type and hooked up with a variac to power.
 At one point the panel lit up with power, then there was a snap
and thought I saw sparks from the 2 large heat guns in the chassis,
then dead. Fuse blown - bridge shorted again.

Seems like they are using a IC on the boards
to handle the switching side of the SMPS, its a Viper35SP
made by St electronics:

Looks like its obsolete / NLA from what I can see so far. Some on Ebay for purchase.
I think the IC runs straight from the line power, rated at 800V.

Should I try the support components around the IC or try replacing the IC?

I am thinking the heat buildup perhaps caused the smd caps to dry out?
