Toshiba 42XV505DB faulty mains power switch

[tom66]

Interesting one here - mains power switch works OK but you have to hold it in for it to work! If it's released it will turn off immediately.

For now, I just bridged switch, to disable it, but would be interested if anyone knows of a replacement switch part # or board. The board is PE0533H but that is going for £27+ on eBay which is excessive for a power switch. I guess it's a common fault.

foto?
if it's a mains push-switch like on old tube tv's then Tidman or Grandata will have them.

Hmm £POA though... will ask them.

Don't mind putting a few quid into it, was only £33 on eBay.

Seller said faulty power switch... I was thinking power supply or something, but nope... first time someone was dead right about a switch being bad.

Re: Toshiba 42XV505DB faulty mains power switch

i cant see it properly in the ebay pic - they are selling an assembly.
can you desolder the switch & post a pic - i may even have one.

[tom66]

Re: Toshiba 42XV505DB faulty mains power switch

TV is currently undergoing test (playing Avatar @ 100% backlight) so will do that at another time.

Yes that's an assembly. But it looks identical to Vince's switch as linked. I am going to look on CPC too.

Re: Toshiba 42XV505DB faulty mains power switch

not too bad I'll probably buy one then.

Re: Toshiba 42XV505DB faulty mains power switch

you know why they fail dont you,
people switch the tv off at night,
the daily arc as they switch it on/off burns the contacts because there is no supression cap.

i used to replace a lot of switches on large sony & philips tv's because of this.

you should warn the customer to leave it in standby at night and not be throwing the switch when they go to bed.

Re: Toshiba 42XV505DB faulty mains power switch

Yep - there is nearly no point to this switch anyway.

Power consumption of a TV in standby legally limited to not exceed 0.5W.
TV running = 220W

This means that leaving it on for just 1 hour is equivalent to over 440 hours of standby usage.

The cost of 1 year's standby usage = £0.57 (4380Wh, 4.38kWh, £0.13/kWh)

Person I bought it off said the switch has been replaced before at a cost of £70, he just got frustrated with it after it broke again.

Re: Toshiba 42XV505DB faulty mains power switch

£70 for a switch?
someone did well - what a rippoff.
it's shit like that that causes people to not get stuff fixed.

i think i would have charged £40 or less.

[tom66]

Re: Toshiba 42XV505DB faulty mains power switch

I would charge £20 if I disabled switch (bridging it, if customer decides they are OK without it), £35 to replace it. This is a refurb job though - buy 'em dead, fix them and sell them.

Also, the "new" switch had an Emos' TV part# sticker on it, so it wasn't even new, it was probably an already worn mains power switch...

Re: Toshiba 42XV505DB faulty mains power switch

In the old CRT days I used to solder a 1.0mF 250v ceramic cap across the switch to reduce arcing and now I recommend a power strip with the little red switch to take of power in the night or when not at home to prevent power on issues that may develop if there is a surge or something.
