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..


Hope this may help;

Connection


A couple possible ways:

1. The VCR has 2 threaded coax connectors on the back. One is input for your cable or satellite. The other is the output to the TV. You would set the TV on channel 3 or 4 (selectable on the back of the VCR). Put TV on channel 3, insert a tape and press play. When the VCR is off, the cable or satellite input is routed to the TV.

2. If your TV has Video and Audio RCA connectors, you can connect the VCR that way. You would then put the TV on Video 1 or Video 2 or whatever your TV set supports.

Good luck!

Vertical rolling in t.v.


Kamal, You need to find the sawtooth waveform which is generated by the vertical oscilator. There will be a pin on the IC that should show the waveform. If it is not there, then the IC is bad. If it is there, then there is probably an amplifier stage prior to the deflection yoke that has a problem. Either way, the sawtooth wave is not getting to the deflection coil which is why it is rolling. Ther might also be a coupling capacitor which has opened up. Hope this helps.
