Title: RGB 1401a Value of Ceramic Resistor location R85 Post by: tvmaster1 on August 09, 2012, 10:48:01 PM any one have a schematic i need the resistor value of r85 the big ceramic ressitor located right at the back of the chassis.
thank you would be even better if i could get the schematic for this unit thank you tony thetvmaster1@msn.com :137- Title: Re: RGB 1401a Value of Ceramic Resistor location R85 Post by: proten on August 13, 2012, 03:03:07 AM Here is one for sale

It's a 15watt 270 ohm..I ended up calling Zanzen for a replacement and he sent me a used one. I never could find one in the catalogs. It must be obsolete...Now can you help me..lol....What is the transformer thats located right below that resistor?

there are some transistors and looking from the back of the monitor is a small transformer\ wish i could help with this but i do not have the drawing for the monitor location or parts numbers. Title: Re: RGB 1401a Value of Ceramic Resistor location R85 Post by: midas touch on August 28, 2012, 10:15:04 PM I think it's marked T-141.. Have you figured out what took out the resistor.....Mine had a bad H.O.T. I'm still learning about these monitors...I guess you are suppose to change some other components when the H.O.T. shorts out or it may happen again....I'm hoping other members could help out with this subject
Title: Re: RGB 1401a Value of Ceramic Resistor location R85 Post by: tvmaster1 on August 28, 2012, 11:13:55 PM that resistor that was bad on mine was just due to heat and age i had nothing else defective on my monitor so i replaced it out of another monitor that was given to me from another source that didnt need it anymore because the monitor had burn in on the screen.
as for the H.O.T i would just check the whole monitor board to make sure their are not any other components that have shorted because it could possibly be the F.B. Transformer ( Flyback). good luck with the repair. i stil havent got mine repaired i am looking for a Processor board if any one has one. tony thetvmaster1@msn.com Las Vegas Title: Re: RGB 1401a Value of Ceramic Resistor location R85 Post by: midas touch on August 30, 2012, 10:39:51 PM do you still need a manual?I have one I could make a copy of it and mail it to you.....By the way ..thats the transformer I'm asking about....Does yours have any marking s on it ....Mark
Title: Re: RGB 1401a Value of Ceramic Resistor location R85 Post by: tvmaster1 on September 07, 2012, 03:11:41 AM i have a few boards with flybacks do you know what one you need?
Title: Re: RGB 1401a Value of Ceramic Resistor location R85 Post by: midas touch on October 16, 2012, 05:28:43 PM The flyback is marked F C O 1412LO6....s.e.m.c.o. If you have you that'd be great....I'll P.M. you with my phone #...Mark
Title: Re: RGB 1401a Value of Ceramic Resistor location R85 Post by: tvmaster1 on October 17, 2012, 03:12:22 AM i will email you tomorrow in the am i have a few rgb chassis at work , i will see if i have one that matches what you need i have some rgb chassis here at home but they do not match what you are asking for.
chat with you tomorrow tony |
