Question about Toshiba 27AF41 27" TV

1 Answer

Red lines across screen

I have a Toshiba 32AF41 tv. It has been shutting off by itself but right before it's about to shut off I notice thin red horizontal lines across the screen then the entire screen turns red and shuts off leaving the red power light blinking. I am not able to turn the tv back on unless I unplug and then plug back in. Any ideas? Thank you. Laurie

Re: red lines across screen

Wow this set has several problems that cause almost the same symtoms. There is a b+ filter cap off the flyback that supplys screen drive voltage th the crt that gets leaky and gets warm when the sets on. Also theres a resistor that feeds the voltage that gets warm and a cold solder connection appears but its dosent look like a bad solder connection so just resolder it. as a matter of fact most of those largewr resistors in this set causes all sorts of complaints soI resolder most of them just to stop any problems and a friend in the tv business still told me in one case he had an intermittant crt. and x ray protection cuircut problems.. Hope this helps GOOD LUCK

JVC AV-36F802 Shuts off after turning on, then red timer on light flashes.

You are describing Vertical sweep failure.
It will be an I.C. with a part number that probably starts with an LA_ _ _ _ and be on a heat sink in the vicinity of the connector going up to the yoke. Try replacing that. But first, check all the electrolytic caps around it for testing dry (sorry - takes a special meter to do it in circuit) or just replace them. May have lost power to the I.C. as well. Look the I.C. up in the free NTE cross reference at Get a diagram of its pinout to find what pins the power and outputs are on.
Hope ya fix it!

Red lines across screen

it sounds like a b+ cap going bad and is intermittant that feeds the the video drivers on the crt pcb or the crt is shorting. I have seen intermittant shorts in crt before.
