Eprom Eraser, how to build

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 is dead. it makes a loud squealing noise also. hoping i could get a little advice on servicing the set back to health

Change the HOT and the IHVT..

very common.. kip

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.
