HRM29PS, 33S, 33PS, 37PS, GT2825, GT2925
|
In bright scenes the image appears blurry, silvery. | Excessive level of video signal entering or leaving the transcoder. | On hrms TVs (29/33/37), check that on the pci av control, the resistor r144 is 560r (only for phase ii transcoder, if not, replace it with one of this value. | |
| GRADIENTE |
GT1410/2010
|
Remote control with intermittent operation, that is, sometimes it does not perform the requested function. | Replace the value of the CR20 capacitor from 1μF/50v to 2.2μF/50v on the main PCI. | ||

GTV-142
|
Lack of audio | A cable. short speaker, causing connector p1603 to disconnect | Replace the cable | |
| GRADIENTE |
HRM290S
|
Does not accept remote control commands | Probable cause: terminals of the PCI cable connection of the LEDs touching the metal shield of the remote control sensor. | You must place adhesive tape on the metal shield of the remote control sensor, on the side that comes into contact with the PCI connection of the LEDs. | |

LINHA NEXT 14/20
|
On screen pulando. | Add a 47nf/25v ceramic capacitor in parallel with the rl83 2.2k (in the schematic it appears as rr83) | ||
| GRADIENTE |
HRM29S
|
Lose heart em pal m | Switch the device to video1 or video2 | Leave video inputs 1 and 2 open (no signal) connect the frequency meter to point mv-11 adjust cv-39 to a frequency of 3.579545mhz. The CV-39 capacitor must be replaced. | |

LINHA GT
|
It takes time for the color to appear | Replace the 12k/5%/0.16w melf rc11 resistor with a 8k2/5%/0.16w carbon resistor | ||
| GRADIENTE |
LINHA NEXT 14/20
|
Momentary loss of color when changing channels. | "replace resistor rc11 from 12k to 8.2k" | ||

TVS 14/20 CHASSIS TX75
|
Noise when connected to 220v | Check the voltage of 119v +/- 0.5 on cp51 for tv 20 and 108 for tv 14. if necessary, adjust pp52, change the capacitor cp54 (10nf) for another 22nf | ||

GTV142
|
When the TV is turned on using the TV on/off button with the video on, the power supply turns off. The same happens when you turn off the device using the power button on the c. remote, or from the panel, while playing a tape | Add a 1k8 x 1/4w resistor in place of jumper j4 (pin 8 of ci str-s6707) | ||
