Joe, There is much information I am sure, archived at www.google.com Here is the latest one I had(below)...though this was for a shutdown problem. Your customers set may be shutting down and they don't know it. Be prepared to bring the light box with you. Tritronics repair kit is good, if the problem is the splitter..but then again, only if it is shutting down. Removing the lead from the splitter, if the set fires up, bad splitter. My suspect is the power supply kit took out the main fuse..if the set is really dead. You need to ask the customer if the set has been worked on before to get an idea as what may have been replaced. Add to this list the CR4118 mentioned and take one of those, just in case and a 5 GMA fuse.
I'll send you one of my invoices that has all these parts on it.. There are some other caps in the circuit, but you can use generics..I use RCA for the ones listed in the group I am sending you. 1. First, the HV block was arcing at the Flyback lead. 2. Planned to replace the power supply parts, since this set had the original parts...replaced them all. 3. Replaced flyback..old one rang good, but had a pin hole 18 months ago I covered with HV putty. 4. Replaced CR4118..tested fine. 5. Replaced the power supply parts again, assuming I had a bad part. 6. After the last bout of suggestions, found the resonator area looked a little damp. Unsoldering, I could smell it...replaced resonator and the cap beside it. 7. Removed CR4119, CR4120(I think)..sit right below the power supply transformer, beside each other. These two had definite leakage. 8. Now, all the wave forms in the power supply looked fine and micro voltages were fine. This is when I saw where the real audio board was. 9. Removed both connectors and set fired up fine. Replaced the one(leaving J1903 off) and set still fired up. 10. Checked both IC on the heat sink and found one shorted 1 and 4..comparing to the other one I knew this wasn't right.
