Can u get into ur tv menu with the universal remote?If u can't tries it with the tv manual buttons look at on the botton of ur tv have manual button said menu.Press it go into the tv menu.Look inside the tv menu for functions like Close Caption like CC1,2,3 and Text 1,2,3 make sure all CC1,2,3 and Text 1,2,3 turn it to all off.Black square box will disapear.Can't do it in the tv manual button etheir.Try website like Remote.com to buy the tv origial remote to close Close Captioning and Text 1,2,3 to all off.
I had a similar problem, except I could make the screen and sound come back by banging on the the TV. I opened the TV and poked around on the circuit card and found a loose pin on one of the regulators, labeled C3852. I resoldered the pins and its working fine now.
its batter in a shop were spares can be found. in side a tv there is a photo senser which converts light into electrical signals.
let the photo diode be tested
and also the remote you have on other toshiba sets to confirm, if remotes are a problem or not.
remotes have codes to change to another remote, 060, 019, 014, 052, 059, 075.
two things can be affected, a tuner if you were using out door
the other one is the power supply. the tv sensed a high voltage (surge)
firstly you need to repair a supply, check the following.
i rectifier diodes at the power supply
ii power trasistor, driver trasistors diodes, zener diodes
ii fusable resistor near a power transistor
after the tv will come on ----if they will be light on the tube then test a tuner, by putting in signal.
If you are getting static on screen you dont necessarily rule out the FBT, but if there is a fusible resistor by the FBT that is blowing it may be supplying current to the vert IC, the IC may be shorted internally or externally, check your connections and try replacing IC. Also check the pump up cap and if it is powered off the FBT the rectifier diode.
A white like across the screen means that the vertical circuit has stopped working. Look for a small fuse that looks like a resistor near the vertical output IC, replace that fuse if open and resolder the pins on the vertical output IC.
We had the same problem, for the same model of Toshiba TV. Had it repaired yesterday. Turns out the problem was the power supply (P.C.B).
The total cost was $192.66 Canadian funds (taxes and labour all in). Our model was 6 years old, buts its playing like a brand new unit now. Hope this helped ...... Good luck
