SOURCE: no picture/sound

There is a PCB mounted 1amp fuse that may have blown, if this has blown the TV will be completely dead. The fuse is available from RS

SOURCE: On start up the TV produces a loud buzzing sound,

Major failure in the power source. If it's worth repairing only you know that - without actually seeing the tv i can  do just a very uncertain estimate of the price of the repair: around $150.

Why did my Quasar TV (1993) picture go out again, blue line across the screen? We had it repaired, 3 months later no picture, same blue line.

Sounds to me like something else is causing those parts to fail. It should be under warranty but depends on the repair shop. Why not just buy a new one.

Here are some choices for a new one:

RCA 42 LED42C45RQ Class LED 1080p 60Hz 3 4 ultra slim HDTV

Why did my Quasar TV 1993 picture go out again blue line across the screen...

LG 24 Class 23 6 Diag LED 720p HDTV Black

RCA LED32G30RQ 32 720p 60Hz Class LED HDTV Walmart com

My lg 29inch ultra slim can not show pictures

LG T.V.s can show pictures.
Just make sure they are in the right format.
I'm pretty sure .jpeg or .png should work.
