Toshiba CF32G50 32 TV Toshiba CF32G50. It turns on and has sound. There is no picture. Fuse F301 blows immediately.
Could you help me, please
Thank you David.
I think you have a vertical problem. Turn up screen voltage to see if there is a tin horizontal line across screen. If so replace vertical output IC and the 100uf/35v capacitor in the vertical circuit.

Please immediately stop using this device and send it to Toshiba for a repair or replacement. It's not normal for a tv to blow fuses like this and could be a fire hazard. Thank you.
This set, I am sorry to say has no bulb and has no ballast circuit. There are three picture tubes inside this TV set. What exactly was the part you pulled out? Can you post a picture of the Part you pulled out?
Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.
Check the fuses on the ysus & zsus boards. Are any fuses on boards open . Disconect power cabels to ysus board first {board on left} . put tv on . if the light is green the ysus board must be replaced.
all sets must have rated fuse for protection. some units now use what is called a PICO-FUSE.this type of fuse is soldered into the pc board. usually marked with location i.d. F301,F901,F400. etc. these fuses look like resistors or in-line coils. check continuity w/ohm meter. if new fuse blows as soon as you plug in tv, suspect bridge diode ciruit or main filter cap(large ripple filter by main fuse. if new fuse blows when you try to turn on, suspect 130v regulator or high voltage short(horizontal-output, flyback transformer) good luck!
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.
