What is happening is you have no vertical deflection,your video signal is out. make sure the tv is unpluged from the outlet,take the back off of the tv,then useing a desoldering iron,and wire wick for unsoldering,and a ohm meter set it to ohm scale.Locate IC 1509,and Q1505 and replace if bad. Check all solder joints for cold joints and resolder them. Check all connections.......hope this helps..........
There might be another solution beside the trash can.
You see often with audio problem the fault is the audio output i.c that is gone.
Also in the tv menu you may have speaker on/off, make sure they are on.
If it still doesn`t work then you may want to try the audio out connectors at the back of the set,there may be sound there.
What you`ll need is and audio system with aux/cd/tape input and a rca/phono stereo cable.
Just connect the tv out to any free input and turn up the volume .
By the way the tv audio out may be variable(option in the audio menu) which means that any amplified speakers(computer speakers) could be used as long as you have rca connectors on the end of it.
Hope this will help. Good luck
This indicates "vertical stop," meaning that the TV's vertical output circuit is not working. A number of thing can cause this: failure of the vertical output IC or related components; bad solder connections to the vertical output IC (a common problem); power supply trouble keeping the vertical circuit from operating (also a frequent cause). Without having the set available, it's impossible to offer any suggestions for you to attempt repairs beyond looking for bad soldering. Other troubleshooting would require the circuit diagram (often available from the internet), tools and experience working on a live chassis. If you really want to keep the set and don't feel up to self-repair, it might be worth getting an estimate from a shop. These Sonys are nice sets.
You could try touching a soldering iron to each joint, but if tv had perfect image before turning off, could be a bad flyback. Cheap part and easy repair BUT must know how to discharge any high voltage if any stored in capacitor of flyback. Might be a good repair to take in to have a pro fix it.
So far you have done all you can and you have done everything right. The fact that the TV turned off by itself and then turned back on by itself suggests that one or more solder joints have come loose inside the set. A qualified tech should find this easy to fix, and Sony sets are always worth repairing, so it is now time to have the set serviced by a tech experienced in Sony standard sets.
