I have a bad trimmer/potientiometer on my zenith tv power board. It controls the horozontal width of the picture. It's a one turn trimmer with a range of 0 to 2 ohms, with top adjustment. I have a spare board, so I obtained the range from it's good trimmer. On the back it has only 857-08 and 8605 on it, with no manufacturer listed. I am having trouble cross-referencing it. The existing trimmer is defective, testing open. I need an accurate description of this trimmer, so I will know what to order for it's replacement. Plus where is a good source to obtain one fron?

With a MODEL NUMBER a person could try to locate the service literature. If the service literature is found, with a LOCATION NUMBER a person might be able to find it in the parts list or on the schematic. If it is found in the parts list, there may be a part number, etc. Rolling Eyes

I got some help, and found it is a 9mm, single turn, 2K trimmer.

great. We'll be sure to use this info to help us next time we come across a board with no model number.
