Question about Sony FD Trinitron WEGA KV-32HS510 32" TV
7 blinks is an error code for "Horizontal Deflection failure". Once the unit gone to this fault, it will automatically shuts down the unit. This kind of symptoms is not DIY if your not handy with electronics because you will work in the high voltage circuitry section where the flyback transformer located.
Faulty electrolytic capacitor in this section will produced an out-of-regulation condition and will vary the high voltage output of the flyback transformer and will trigger the X-ray protection circuit. Sometimes it will work normal but there's a time it can no longer stable itself and will gone bad. Bad solder joints (cracked,dried,cold solder) will do the same symptoms and this section is prone for that because of heat build-up upon operation.
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to look for a qualified tv technician to isolate the symptoms.
Also, check if your unit is still under warranty/extended warranty period, avail it because the manufacturer will fix it for free. Don't attempt to open the back cover because it will void the warranty.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
