I own an Akai VS-S99EOG, which is very similar in circuitry with Mitsubishi HS-E70. The unit was bought by me 16 years ago from a previous owner. Been using it for 8 years and for the last 8 years I retired it (not used at all). Now I decided to give it a try. Unfortunatelly it developed a series of problems, some were solved by me (like replacing a melted belt), some by a friend with knowledge in electronics and hi-fi enthusiast. Unfortunately there is a problem that persists and has eluded him so far. The problem seems to lay in the chroma path during play operation, as it messes a bit with the colors (horizontal stripes). The unit is recording very well in both VHS and S-VHS, but has this colors problem in playing both VHS and S-VHS tapes. My friend has another two JVC S-VHS machines, he could test the Akai recordings on them, the problem seems to lay in playing mode. Any idea where he can try and find the problem ? We do have the schematics, oscilloscope and ways to measure electric components, voltages, etc. Any help and suggestion is appreciated. Thanks.
