Part Info Needed, Toshiba CRT TV

Sep 06, 2006 4 Replies

Model CX28510, Chassis: TAC9005. Resistor in p.supp. open, no way to tell value, please help identify R873, (1/2 watt flameproof). Thank-you! Cheers, Steve



Don't say no way...my dad (an old oil field welder) always said "there ain't no such word as can't in the oil field."

There are several ways in addition to #4 that you are trying here.

  1. Get the service manual and check the value. There are lots of resources online to do this.
  2. Contact a supplier for Toshiba parts like Andrews or Tritronics and ask their research dept or check their online search engine.
  3. Measure the two halves of the burned resistor and estimate the value.
  4. Get lucky and someone will have the manual handy to look it up for you. Sorry, I don't have this one.

Thanks Leonard, but I'm hoping someone has a 'board boneyard' that, at a glance, might have a board similar to this one. The resistor is near the switching xfmr. Thank you once again, will wait for another try at this. Just want to expedite the set is all! Cheers, Steve

These resistors used as fuses are generally easy to calculate. You know what i is flowing, pick your R to keep Pdiss just under the rated P.

I assume youve fixed the real fault first.

Change out the Caps near the rgulator first and then get a 910 ohm flameproof 1/2 watt resitor and you should be goof to go
