Title: need new chassis need to know what ones will fit tube
Post by: arcade1213 on July 15, 2009, 02:04:46 pm

installed a cap kit and it fried a resistor looking for replacement chassis.its a 25 inch with a hantarex chassis in it right now.looking for a chassis that will plug right in.
thanks  :timebomb:

Why don't you have us help you repair your existing chassis?

ok well monitor was working then i installed the cap kit after that it  had no pivture and burnt out the r6 resistor,the chassis is a hantarex mc9000 series 25 or 20 inch thanks

is there another resistor value that i can replace a 33e 1/2watt 5% at r6 resistor with

Value?  No, you want to match values.  But if it fries it again thats a problem.  You need to find out why it's toasting it.

Is there maybe a different type of resistor that I could use I'm having trouble finding 33e.alsi the fist time i turned the monitor on i did not see the resistor smokeing the second time i turned it on the resistor started smoke and although i could hear the monitor kick on there was no picture either time.thank you for your time i hope this information leads to a accurate diagnosis.

Where do you live?  Maybe someone can toss a few resistors in an envelope for you in the post.

if any one has a couple of 33e 1/2 watt carbon resistors pm me and i can give you an address to send them to.thanks

Some Hantarex monitors had the capacitor polarity marked incorrectly on the circuit board. When you replaced the capacitors, you were carefully noting the polarity of the caps you took out?

checked the scematis and there appears to be two capacitors that were marked wrong on the board the + is the neg and the neg is the+ guess i should trust the schematics before i trust the board.where do i proceed from here are the capacitor bad now since they were installed backwards.thanks

The capacitors inserted backwards are likely bad.

thanks for responding to my post.i take it i trust the schematis before i trust the board labels.also i guessing the backwards installed capacitor would be shorted so easily testable with a ohm meter.thanks

Sometimes changes are made at the factory, were the capacitors in there 'backwards' having been replaced wrong or were they like that from stock? It's very possible that they were meant to be in the way they were originally.

I have an MTC9000 and my chassis doesnt even reasonably conform to the schematics, even my transistors are all different types and values but thats how they made my one and it works fine!
