Hi you will be able to get the schematics for your telly if you use ask.com and type in the box. schematics for sony KV-T25SZ8 after typing that it will bring up a list of sites with the schematics you need just go through each site as you will find some sites that dont charge for the schematics then when you find it download and then you should be able to find the part you need. The schematics will give you circuit diagrammes and will have all the parts and part numbers in a list after the diagrammes. Once you find the part number you need if you then go back to ask.com then type in: capacitor cross referance this will then let you type in part number and then it will give you a list of compatible parts i have done this a few times and it saved me some money as i didnt have to stick to the one brand of parts. If you have trouble locating the schematics or part number let me know and ill have a look for you ive always found what i needed by using ask let me know how you get on ok

KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.
There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.
If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.
Since this seems to recover for a while, I'd first look for poor solder connections on the board. If you can solder, resolder any connection that appears grainy or has rings. Let me know if that resolves the problem. If not, the likely part is a bad capacitor in the kine bias circuit. I'll look up your specific model in that case and get you specifics.
Id you have no TV repair experience, play it safe and take the set into an authorized Sony repair place to estimate the cost to repair. Yes I know it would be nice to repair, but how much do you know about component level printed circuit board repair? You will need to first get a service manual, know how to read a circuit diagram, thats a schematic, and know how every circuit works with each other to make the TV set operate. I do appriciate the fact you would like to repair this yourself, but there is no magic fix in most cases when it comes to electronics. There is circuit diagnosise involved. Best advice would be to call in a pro to assist you in these types of repairs. Good Luck
