This Tv was given to me, but it won't turn on and the standby light stays on. What different things could I try to repair it? Fuses, switch, or a way to test for the problem? Any help would be appreciated.

Re: Sony KV-32S45 32"color won't turn on
If you know all the saftey aspects about tv repair then your gonna need some special test equipment to troubleshoot this set. There are no real user serviceablew parts inside this tv as they are all soldered in and you cant tell by looking at them if they are bad. Theres lots of hi voltage inside these sets even afterv they are unplugged for awhile. if you know all the saftey issues your gonna have to first disconnect the horizontal output transistor and measure it with a good ohm meter. If it measures bad ythen order a hi voltage transformer and replace both at once. If you dont have this equipment or know how to unsolder and solder then you should call in a pro to assist you with this repair. Good Luck

Visit this site for details. All information about this type of fault [2 blinks of standby light to sony Trinitron]; are described here in detail. "Electro-help", is the name of the site. Search for it on Google.
Try unpluging from the wall and theplug back in and try turning back on to reset. Sometimes holding the power button in while pluging back in will reset it, every brand is different for the hard reset.
To get the right colors, especially a plain white, requires the right mix of red, green and blue from the picture tube. Sony TV sets have a circuit called AKB that automatically keeps the picture tube balanced by adjusting the signals to it. If that balance can't be achieved it shuts off the picture. This may due to tube aging so one of the color guns is too weak to adjust, or failure of parts in the AKB circuit itself. If the sound stays on and the power light starts blinking when the picture goes off, this is likely why.
On the other hand, if the set is turning off completely with no picture, sound or power light, the set may have power supply problems or defective parts in the picture tube high voltage circuits.
Since there are several possible causes, this set needs to be checked by a technician who can diagnose the problem and decide what needs to be done. It's not a simple thing I can point to and say "change this part". If the picture tube is the cause, it's better to replace the set. Otherwise get an estimate, then decide whether to fix or replace.
Please check batteries in remote that seems not working. Sony TV would either turns On or standby light will blinks if TV gets any internal problem. You question shows standby light stays On that means TV does not receive power on command from remote. If standby light is blinking in sequence, let me know how many times it is blinking and also intimate exact model number of TV to find out possible solution. Thanks.
When attempting to turn on the set, the standby light should blink for a a while then stop once the picture comes on. If a problem is detected internally, the standby light should blink in a repeated pattern. Please count the number of blinks that are repeating and we should be able to help.
Five blinks means - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
