Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Olympus T-100, write protect shows on the screen & won't operate ??


Look at your memory card. SD/SDHC cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

Tip

Protect your device screens properly!


The best advice I can give if you are worried about the safety of your cell phone screen and the durability of the glass is to protect it properly.

If an Otter case is not available for your phone, I highly recommend the Skinomi Tech Glass screen protectors in conjunction with a Caseology or Mercury TPU case (all available on Amazon).

The lip on the edge of the case protects the screen from most damage that occurs if your phone falls to the floor.

The glass screen protector helps protect your screen glass while still allowing you to use your phone without the plastic feel of vinyl screen protectors.

It costs a little extra, but it's worth doing without the extra hassle later!

Camera is locked up. screen says it has a 'protected card'


there's a write protect tab on the card. if this is in protect them you can't write to it [save photos]Also, if the tab is in the right position, the sensor in the camera is either blocked [optical] or damaged [electro-mechanical]If it's blocked, use 'dust off' canned air to blow out the card slot.If it's a switch, it'll have to go in the shop.
Hope this helps.

I cant take photos anymore and the LCD screen says CARD'S WRITE PROTECT SWITCH IS SET TO LOCK.How can i solve this problem?


You didn't specify the make and model of your camera, so I'm going to assume it uses SD and/or SDHC cards.
SD and SDHC cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.
If this doesn't do it, try another card.

Iam using microsoft 2007 but when try to write something write.it says this modification is not allowed because the selection is locked please help me


This usually means that the document is protected. If you click on the Review tab you should see Protect Document on the far right hand side of the screen. When you click on that, you should see Restrict Formatting and Editing in the drop down. Click on that and on the right hand side of your screen you will see options. If you see "This document is protected from unintentional editing", your document has been locked. Click the Stop Protection button at the bottom of the sidebar. If it doesn't ask you for a password, you should be all set. If it asks you for a password, then the person who sent it to you doesn't want you to edit the text on the page.
If that's not what you see, let us know. Hope this helps!

How do I enter the Test Mode on my RISO 790 duplicator?


Do you mean into the unprotected mode?, if so

Turning OFF Protect mode in a Riso MZ 790u (and other models I'm sure).

1. Go to Admin Tab on the main console screen and scroll to the "Protect" button.
2. Select (press) the "Protect" button on the screen; printer will go through a reset function (takes about 3-5 seconds).
3. After printer is finished "resetting", pull out one of the master disposal boxes (doesn't matter which one).
4. Press the "Protect" button again.
5. the screen should say "Protect = Off"
6. You're done and your machine should be un-locked now.
