PhilipsFL2.16
vertical black lines in picture.Supply 141V various. Replace SOPS-PCB (4822 310 31993).
PhilipsFL2.16
Totally inoperative. Hardware protection vertical deflection.Check IC7450 (TDA3654Q/N3; 4822 209 73308).
PhilipsFL2.16
Sometimes vibration in vertical direction.Replace C2410 (150nF 5%; 4822 121 41854) on LSP.
PhilipsFL2.16
Jumping vertical picture. Wrong colours. Sometimes no sound.Set is switching between PAL-NTSC-Secam. Check soldering joints of T7119.
PhilipsFL2.16
Distortion in vertical lines.Rimple on micro sops? Check elco C2261 (100uF/50V; 4822 124 40255).
PhilipsFL2.16
Distorted East-West & jitter on vertical side lines at switch-on.In the FL1.16 and FL2.16: Replace position T7610 on the LSP by BD536FI (4822 130 63508). Delete position 2615. Replace position 2611 on the LSP by 2,2 uF (4822 124 41576). Replace position 3608 on the LSP by 1k (4822 051 10102). In the FL2.24: Replace po

Distorted East-West & jitter on vertical side lines at switch-on.Replace position C2611 on the large signal panel by a 1 uF capacitor: 4822 121 51319. REMARKS : The East-west distortion shows a barrel-shape. The jittering only occurs at the centre of vertical lines at the left- and right-hand side. After warm

vertical position can not be adjusted.Add position 3464 (1k8; 4822 053 10182) on the Large signal panel between 1L30 and pin 9 of IC7450. REMARKS : The range of the vertical shift will be changed. Introduced in production in week 9317.
PhilipsFL1.6
vertical line interference on CH 2, 3 and 4 (spook).General remarks: - Place the antenna at a good distance from the TV set. - Use good shielded cables, connectors and splitters. - Avoid HF amplifiers, splitters and rolled-up cables just nearby the TV set. - The stronger the signal is captured the less p

After one hour picture jumps verticallyBurst key 50 (BK50) on LFR (digital scan) box is 10Vtt with 50Hz frame sync. instead of 5Vtt without frame sync. Check D6001 (LLZ-C5V1 4822 130 80884) on LFR box.


Assistência TécnicaAs dicas apresentadas destinam-se a técnicos de eletrónica, a tentativa de reparação ou assistência sem ter conhecimentos de eletricidade e eletrónica, podem provocar danos mais graves aos equipamentos e, devido a tensões muito elevadas em alguns circuitos, graves danos fisicos que podem constituir um risco em determinadas reparações.

Não arrisque reparar equipamentos com tensões elevadas se não tiver conhecimentos técnicos para o fazer em segurança.
