Question about Toshiba 36A50 36" TV
My 36"36a50 suddenly will turn off and the little red light by the power button just flashes, cannot turn it back on until it is unplugged and plugged back in. in a few seconds after turning it back on it shuts off again. when it does come on its a red screen with lines through it. can this be fixed? i did take the back cover off and blew all the dust out, did not fix the problem
Some el.components are loose on tv circuit board.I have removed the back cover,supported tv picture tube 45 deg.against wall.This tv is heavy!One screw on left holds the circuit board to bottom case.Removed and supported this board on few heavy books.Turned tv on and gently probed all the componets on top of the board with plastic drinking straw.In my case transistors Q-830 and Q-421 needed resolder loose joints.These components are mounted on flat aluminium heat sink strips located sligtly left of center of the circuit board.Also blobed bit of silicone into base hole and foot of alu.heat sink to support it.
