Reflowed the tape PCB in the sound in section and tape drive is fully working now Thank you very much for your help!
Quote from: Purity on 15:41, 20 May 23Sadly this is still not working :-( The tape drive is functioning but I am not hearing any sound from the tape and it's not loading any games. I previously reflowed the deck and this seemed to do the trick, but now not working. I changed all the caps apart from two - the 0.47uf one as I didn't have any and the non polar cap in the middle - can i change this for a polar cap of the same value?Pressing the del buton i can hear a sound
Quote from: Purity on 14:04, 07 May 23I just watched this video at position 9:45, and I can see that the white plastic bit moves from a left position to straight.Mine does not move at all. It stays in exactly the same position. What causes that to happen?
Quote from: Bryce on 09:58, 31 May 23That could indicate that the 6324 has failed or isn't getting power.Bryce.
Quote from: Purity on 21:15, 31 May 23Absolutely spot on again Bryce. It was an issue with the voltage. I was reading 0.8v on pin 4 of the 6324. There was 5v at the connector so I measured at R306 and C315, and suddenly the sound began to be be at the correct volume. I reflowed both components and it seems to be consistent now. Thanks for the help!Thanks Rabs. If it continues then I will check this
Quote from: Bryce on 08:58, 01 June 23Then congratulations again. Looks like it should be fully working now. However, neither of those components are responsible for the voltage to the Op-Amp, I'd check/reflow all joints around that area, especially the Op-Amp pins.Bryce.
