TV N15 fuses?

[Stephen Varden]

Hi all,

Does anyone have any information on miniature N15 type fuses, these fuses resemble a transistor in shape,but obviously being fuses have just two legs. My query relates to the suffix letter.

I recently had a N15 P fuse blow in the 115 volt HT line of a Sony television. According to the circuit diagram and parts list this is a 0.6 amp type,but that is all the information given,there is no reference to the type of fuse ;slow,fast anti-surge etc or to its working voltage. I have recently obtained for a friend a N15 E fuse.

Will this type be suitable as a replacement or must I use an N15 P  type, as fitted to the set from new.

 

Any information on these types of fuse would be much appreciated.

"them" fuses are really called IC Protectors........a super fast blow device that must be replaced with an exact same device number.   There are two case styles.....N15  or F15.....the rating is the same and as long as it physically fit in the circuit they can be substituted for each other.   Regular fuses, even fast blow, will not provide the proper protection.............more damage could result.

Thanks to you all for the advice on the N15 protector. I shall make sure I
replace the orginal with the correct type. I was just curious if anyone
actually knew what the various ratings were for the N15`s with the different
suffix letters. As I mentioned in my orginal message, the only information
given by the Sony service manual was that it was a 0.6 amp device.

Yes, the N15 or F15 ICP is rated at 600ma........no matter what the suffix
letters are.

when these type first came out a list i received from a dist. showed most icp f and icp n as same value not all this could have been a misprint as it was early released info i do not remember mfg. I checked my stock of icp,s and all have suffix letters my guess is this is proably a batch code as this is not referenced in any info i have if you find out something else please let me know.

You have the virus (some call it a worm) known as
JS/Kak (aka WScript.Kak, Kakworm, VBS/Kak, etc).
Here are detailed and complete clean-up instructions.
Unlike most earlier instructions, including those
posted by many antivirus vendors (who are fixing theirs
at my suggestion), these instructions not only remove
Kak but explain how to make your machine *immune* to
re-infection from Kak, or infection from any future
viruses or worms that depend on the same security hole
to get into a machine.

Note: Kak spreads via Email. Since you were infected,
you'll have been sending infected messages. You should
check your Sent Items folder **after** applying **all**
the fixes below and Email warnings (and an apology!) to
everyone you've mailed since being infected.

Note^2: Too many descriptions of how to deal with Kak
ignore the fact that infected users have mail folders
full of infected messages which will hit them again next
time they are read **if the security hole Kak depends on
is not closed**. Thus, when cleaning up Kak you
**MUST** follow my advice about Outlook Express security
settings **AND** installing the MS security patch
referred to at the end of this message.

In the prescribed order -- don't ask why, just do it:

First, stop using that machine for Email and News. In
fact, close down all applications. In the instructions
that follow, start any mentioned application **only**
perform the stated configuration changes then exit the
application.

Second, check the Restricted Sites security has *all*
ActiveX support set to *disabled* (that prevents people
choosing the wrong option when given the choice if
"prompt" is set) and if it is not, set it that way.
You do this on the Security tab of Tools/Internet
Options in IE or the Security tab of the Internet
Options control panel (they are both routes to the same
controls). If you do not know how to check this, just
select the Restricted Sites zone and click the "Default
Level" button to reset the defaults for that zone --
they are near enough.

Third, set Outlook Express so Email is considered to be
in the Restricted Sites zone. This is on the Security
tab of the Tools/Options dialog.

Fourth, delete the Signature definition in Outlook
Express for each afflicted user identity (if you do not
know what that means, you *probably* only have a single
identity so only need to do it once). These settings
are on the Signatures tab of the Tools/Options dialog.
In theory, it is now safe to use Outlook Express 5 for
reading and sending Email -- but don't...

Fifth, delete the files kak.htm from the Windows folder
and <name>.hta from the Windows system folder. <name>
is an eight character string representing a hexadecimal
number -- i.e. it consists of some combination of
characters 0-9 and A-F. There could be more than one
of these files -- they should be 4116 bytes in size --
delete them all. If there is more than one, then you
should find out about Outlook Express user identities and
tidy up the siganture settings of all identities (that
is more aesthetic than necessary, as deleting the
kak.htm file effectively disables the signatures anyway).
These files have the hidden file attribute set -- to see
them you will have to change the default settings in
Explorer. If you are unsure how to do this, select Help
from the Start menu, click on the Index tab then, under
Win95, enter "hidden files, viewing" or under Win98 enter
"hidden attribute" and view the topic that is found.

Sixth, edit AUTOEXEC.BAT and delete the two lines
involved in creating and deleting kak.hta in the Windows
Startup folder. If AE.KAK exists in the root of C: and no
changes have been made to AUTOEXEC.BAT since Kak infested
the machine, you can delete (or rename) AUTOEXEC.BAT then
rename AE.KAK to AUTOEXEC.BAT (it is a Kak install-time
backup of AUTOEXEC.BAT). Check the Windows Startup
folder and delete any file there named kak.hta.

Restart the machine and watch closely for a process called
Driver Memory Error that **only** appears (and briefly) as
a button on the taskbar. If that happens, you missed
something or did it out of order. Start over. If you get
here a second time and still have this process starting,
please Email me for further assistance.

Assuming that all has gone well, go to:

http://www.microsoft.com/technet/security/bulletin/ms99-032.asp

read it, download then run the offical MS patch that
closes the security hole that Kak depends on. After doing
that, you can reset your Email security to the Internet
zone, although I certainly do not recommend that!

After all this, you will almost surely have one or more
messages carrying the Kak code in your Email folders.
Unless MS re-introduces the security hole Kak depends on
in a future IE update, those message won't cause you any
grief though forwarding them to others would be unwelcome.
Note also, that any copies to self you've kept will also
have active Kak code in them. Short of getting a virus
scanner that can parse OE mail files, the only vaguely
satisfactory workaround to the "problem" of possibly
forwarding one of these "infected", saved messages is to
configure all your user identities to send text-only Email
rather than that HTML rubbish that is the OE default.
Thus, setting text-only Email sending is a *very good
idea*. Note that to set this configuration fully, you
must not only set Tools/Options/Send to "Plain text" for
the "Mail sending format", but also disable the "Reply to
messages in the format in which they were sent" option
(which is also on the Tools/Options/Send dialog).
