Toshiba CF3062A Have a model Toshiba CF3062A that has a vertical problem no vert ical from the bottom not up to middle of the screen have replaced most of the parts in the vertical circut and ideas Thanks Very similar problem; but raster fills as set warms up, although lower 50% is distorted

    It is a chassis 9150. Last night I decided to look into the problem further, after finding one of the power transistors loose on the board. After removing the board so I could resolder the leads, I saw a faint oil film under C305, C342 and CD06. A previous post from someone back in 2006 recommended replacing C305, so this was perfect correlation to what I was seeing. Resoldered transistor (sorry, can't remember which one, and I have it all back together now, but it was close to C305), replaced those 3 caps, and it works like a charm! You guys are great, thanks.

In the old days that means your "flyback transformer"needs to be replaced.

Take it to a TV tech or junk it and buy a new one. That might be cheaper.

I have a 36 inch toshiba tv model # 36A50 and i have black bar at the top and one at the bottom i only have approximently 3 or 4 inches of screen in the middle to watch. what would it be? that problem...


For one thing you have a vertical problem and since it got that way gradually you can bet that there is a bad capacitor in the vert. circuit(pump-up cap) as far as the price goes it depends on your local servicemen, i`m in canada and that sort of problem fixed at home would run around a 100.00$. good luck

I HAVE GOOD AUDIO BUT A THIN LINE IN THE MIDDLE OF THE SCREEN THAT HAS VIDEO. ALSO THE SCREEN IS BLACK ON THE TOP AND BOTTOM WITH THE THIN LINE OF VIDEO IN THE MIDDLE.


Have you vertical deflection circuit checked for bad Vertical IC, and or Bad vertical Capacitors in the vert output section for the deflection board. Also have Vertical output Pump up Capacitor replaced, also have B+ voltage check coming from flyback transformer, for any open fusible resistors

Toshiba TV (about 7 years old)


You had parts in the vertical deflection circuit failing, most common are the vertical output IC and possibly several capacitors also in the same circuit.

Thin horizontal line with a Toshiba CF3062A


This is a problem with the vertical circuit that is usually a defective vertical IC. This part costs $10-$20 and is easily replaced. Sometimes there are capacitors in the same circuit that need to be replaced as well. Dan

No picture no sound


Did you mean the picture is collapsed only in the middle horizontally(white line appears on the middle part of the screen)?
If that is the case, maybe vertical IC failed or loose connection.

Look, replace all capacitors around horizontal transistor, if dont work, adjust eprom.

JVC AV-27790 - single horizontal line


Since Intermitant always inspect the vert ckt for bad solder connections. If not replace the output IC they're cheap and most likely the problem If you still have lines on the top or bottom I would replace all of the electrolytic capacitors in the vert ckt also. Without much test equipment rebuilding the whole little ckt is the best way to go.

Vertical hold


You dont have enough vertical sweep!! Best thing to check is the vert output device and I think its an IC . BUT before that check the b+ going to that device and see if its low. I will run through a silicon diode right next to the ic. Measure both sides of the diode and if theres a big voltage drop then the diodes bad. Now also these sets are common for the b+ filter cap off thge flyback transformer. Its the voltage line that feeds that diode and the vert output section. Now measure all caps out of cucuit as most will measure good if you dont. Also just for giggles right nrxt to the big IC that has the vert ,horizontal video and sound drive there is if im not mistaking the vert parts start with c4-- or the ic will be ic4-- Its a small cap that will sayc4-- attached to nothing but the ground and one pin of the ic. I've seen this cap cause all sorts of vert problems in the past as its the vert waveshaper capacitor for the vert osc/drive. Good Luck
