Eprom Eraser, how to build

[Andy]

gAnd a lot of what you learn will be WRONG.

An EPROM cell will get erased by any electromagnetic radiation shorter
in wavelength than some limit determined by the device physics. (You
can
even use X-Rays is you can find a source powerful enough). --Mark

Andy replies:

Absolutely. If you put the EPROM in a large bonfire, it will also
be erased and the wavelength is much longer...... Additionally
applying a 25000 volt DC between the pins will probably erase
it . ANYTIME you overload the hell out of something's linear
parameters
with excess energy, the victim usually loses any memory...

However, the best way is to use the device physics to apply the
proper frequency to accomplish the task without risking damage
to associated internal components. In other words, do it like the
manufacturer says.

Otherwise, I found your post very informative. Thanks. I sure
hope your post wasn't some of that WRONG stuff you were talking about
on
the internet .. :>)))))

i also have an RCA TV model f35673MB, Chassis CTC187CL3 that i
dead
it makes a loud squealing noise also. hoping i could get a littl
advice on servicing the set back to healt

Change the HOT and the IHVT..

very common..

I'm looking at exact same fault and same model as yours for a
estimate.

RCA tend to have a run of flybacks to fail on 32" to 36" because these
flybacks are bit underspec'ed.
