Question about RCA F27676BC TV
That's still repairable here some tips need to consider as follow:
1)
Intermittent loss of syncronisation, both horizontal and vertical
The surface mounted power transistor on the teletext module requires
resoldering. As there is evidence of scorching on the board the use of
a more substantial component would be indicated perhaps with small
heatsink
2)
Picture displaced vertically, picture too high or low
This problem was cured by entering the service mode (menu then
4,7,2,5), then pressing the green fastext button to access geometry
settings, selecting VP1 (vertical position) and adjusting as necessary
3)
Vertical line at the left of the picture
Replace L506 on A board, replacement part number 1-407-366-00
4)
Problems with screen size
Look out for 2 x 2.2uF electrolytics (sometimes red in color)
5)
Vertical height oversize
The eprom was found to be faulty (nvm)
Please let me know any update.
