Question about Portable Televisions
Stopped getting power is there a fuse in the unit itself?
Yes there is a fuse inside the unit,just open your unit and locate the fuse.If you aready change the fuse still not working then the problem go deeper.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. This TV monitor is small enough to take to a repair shop find a good one.You probably have to pay $50 - $75 dollars up..Feel free to ask and post whatever the result of your troubleshooting..
Hope this may help;
