Question about Toshiba 27AF42 27" TV
My TV is unwatchable. The picture appears to be totally out of focus with horizontal white lines. There still seems to be color. Sound is fine. The TV is nearly 5 years old. Is this tube shot? Thanks.
You need to consider the following tips herein as follow:
1) Field collapse (horizontal white line on screen)
R710 dry joints. Same as C2146TN & C2546TN problem solved with thanks to Mike G & Barty. Power off/unplug. Get to circuit board underside with aerial socket up-R710 is near top and right of centre-cluster of 4 joints best resoldered
2) Picture is horizontally narrowed and deformed
Capacitor C2913 (390nF, 250V) on the deflector PCB had lost capacity
Please let me know any update
