Bad sound, and a lot of hiss, both in am and fm | Leaky electrolytic capacitors, and adjustment in the monoblock | Replace all the capacitors, without testing, and make a fine adjustment to the monoblock trimmers, this tuner has always been noisy, but you can improve its squeaking. | Trendset |

It doesn't stop at the end of the album | Change the 10n capacitors on the board, the 470x63 one on the power supply, and the LED that goes on top of the LDR close to the arm tower. | The LED becomes weak with age, and dry capacitors only get in the way. When the record reaches the end, a metal piece closes the LED light under the LDR, the record player goes into stop mode, and the solenoid raises the lift. | Trendset |

This television played a trick on me, after I repaired it I tested it and released it, it went back to the workshop, just calling when I wanted, I suspected the c913 but I didn't change it because I tested the esr was good on capacheck and capacitance was ok on the capacimeter, I spent a long time looking for a defect wsound it wasn't I did, until the next day I decided to go back to the c913 when the problem appeared and heat it with the iron and the TV turned on normally. | C913 changes the esr only when it is cold or at room temperature, changing it without measuring, in my case I put a 2.2uf per 100v it was a gem. | Replace c913 (edfesom varjota-ce) | Edfesom |
