Question about Toshiba 32A33 32" TV

Toshiba 32A14 horizontal line

Hi-
We have the dreaded horizontal line on our screen. I've read some of the other posts on this matter and wanted to know if it's worth repairing. I don't have any experience with this stuff and I'd only screw it up more if I tried to do it.

As long as everyone agrees that the horizontal line is some vertical failure or capacitor problem, I think that is what has happened.

BTW, it's actually a 32A14 tv set, not a 32A33 set.

Thanks
FJT

This symptom is characterized by a thin horizontal line in the middle of the screen. This symptom is caused by the absence of the deflection sawtooth current in the horizontal deflection coil.
The trouble is easily isolated by a continuity test and by checking the most likely defective components such as A)open vertical linearity compensation transformer, B) open capacitor and C) open horizontal deflection coil.
Be sure to decrease the brightness first before trouble-shooting if the line is very bright,as it burn the phosphor screen..

Hope this may help;

My toshiba 55pd8800ta now has horizontal lines of picture across the whole screen. The picture and menu are out of sinc. Help!


These lines are called vertical retrace lines. Thin white lines are seen across all over the screen, at about an inch apart. If you wish to get more details, check this site.

It is a 32A14 model. power to house was cut off, electric people replaced phone poles. when power came back on tv wouldn't turn on, no red LED indicator light lit up, and it makes this chirping sound in...


The tv high voltage "H" horizontal transistor IC is dead.That "H" transistor IC sit out side outer wall of the FBT-the flyback transformer,that the big black block of a plastic,with a red wire with a cap hook up to the CRT-(tv tube).Best take to the shop for repair,because part for analog tv are impossible or near impossible to find and do for the replacement.

Where are fuses on Toshiba 32a14 TV won't turn on


The fuses are located on the inside of the set, remove the back cover and follow the power cord in, there should be a main ac fuse near the cord on the circuit board. Toshiba usually has a second fuse further up the power supply.

I have white horizontal lines about 2 inches at top of my tv


You have some bad grounds on the Vertical IC. In addition to this, in the immediate area of this Vertical IC, are a few bad capacitors. Look for this IC mounted on a large heatsink. It may have seven pins . I cannot remember for sure. I have not worked on this particular TV, so I cannot give you specific locations. But I assure the problem is in this area! If you have some electrical experience you can pull this board out. In this case only the caps need replaced and the IC resoldered. Good Luck and thank you for asking. If you have anymore questions, visit me...Thanks Again! Your south of the border tech!

Tv will not turn on


First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner.Feel free to ask and post whatever the result of your troubleshooting..

Hi,

From what I can understand, your problem is:
1. either a single horizontal line (from left to right), very bright, no picture but with sound, if yes then it is a failure of the vertical section. More often, it is the vertical IC that is at fault, sometimes the vertical capacitor. Still, in other cases, it is a case of cold solder; or
2. multiple lines across the screen with the picture overly bright and with sound. If yes to this one, then it is a matter of excessive screen voltage. This is adjustable using the HV Screen control that is at the rear of the Flyback Transformer.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
