Calling electronics gurus

Post by bhodgkiss » Thu Jun 28, 2018 3:12 pm

Hi All

The digital display on my washing machine has gone very faint, and none of the programs work (it won't start), but after leaving it switched on for around 30mins it'll kick into life and works fine

Is this a capacitor on its way out?

I took the main circuit board out last night and couldn't see anything burnt out

Just wondering what it might be - if I can replace a capacitor for a couple of quid that'd be better than £120 for a new circuit board that may or may not fit it (although I presume it would fix it)

Many thanks!

Could well be an issue with the power supply. Could also be a duff electrolytic capacitor, I have fixed a few flat screen LCD tellys that have had power supply problems. When an electrolytic capacitor starts to fail they tend to swell up. You can tell by looking at the top of the capacitor usually if it's duff.

Thanks Karl

When you say power supply do you mean internally within the unit?

I've not looked at the wiring at the plug end (in the wall) as I presumed it wasn't this

You like washing machines?

Could be a regulator invertor

As Karl said it sounds to be power related. I do IT repairs and for example some screens especially imacs that dont power up, is usually an inverter or power board (separate from main power unit).

This applies to laptops as well and becoming more common - all in ones.
