I have 2 of then,I used one of then as a P/C monitor, it worked well for about a little over a year, Turn P/C On ,as always,then a little electric pop sound, you try to turn it on with remote or Manuel the screen blinks quickly ,if you look fast you a see white screen and fast in and out the the bottom right pop up box that has video1, so that's best I can do
SOURCE: Toshiba MD20FP3 Combo does not turn on. Help!
Not unless you have taken the time to learn all the safety issues concerning the HI voltage safety facts, in the repair of electronics? It sounds like your tv has a problem in the sweep/power supply circuits, and since these sets have NO user serviceable parts< its best too leave these types of repairs to a certified electronic technician. Good Luck
SOURCE: TV does not turn on; red light blinking.
your problem is a more technical problem you will need a tech to look at your set if you are not a tech you wont be able to do it your self. contact a tech to repair your set the problem is in the power supply or related circuit.good luck.
SOURCE: Black box in middle of screen
You have CC (closed captioning) turned on and it is set to text mode.....Go to the menu on the remote use the right arrow and hilight "C.CAPT",use the down arrow to highlight "C.CAPT",use the right arrow and highlight "off" then exit button on remote.
SOURCE: power light blinks and no picture
No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC
No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms
Picture fades away few seconds after start-up till no picture.
Sometimes no picture at all. Sometimes picture OK for longer. Sound
unaffected.
Faulty joints on CRT pcb. Cracked solder joints at tube socket
connections on CRT circuit board. Caused variable supply to CRT
heaters. Resolder all socket pins to pcb.
SOURCE: No picture, hear sound, television will shut off after a few seconds.
Take out the bulb (back left hatch door) look to see if the element inside the bulb is broken or blackened - (replace bulb) if the bulb looks OK then it's the ballast that fires the bulb (service call).
