No video no sound on Sony KV32V40.

I recently lost video and sound on Sony KV32V40 TV set. Red light LED keeps blinking next to the power button, but nothing happens. Looks like Tube doesn’t get enough power to get initialize and TV is dead. I disconnect from the wall outlet to cool down. Research on the internet. I found a lot of similar issues where people experience same type of problem. People recommend simple solution by re-soldering IC561 (TDA8172). It is a 7pins IC (TV VERTICAL DEFLECTION OUTPUT CIRCUIT) on V-OUT circuit (module directly under tube on the main board) but it didn't help to me at all. I re-solder everything on the main board directly under the tube, but nothing helped. My next step would be to replace TDA8172 and if it helps that would be great. However, if someone found better explanation why this problem occurred and they have a solution besides simple re-soldering I would like to hear it so is everyone else who has this type problem with same TV set. Please respond. Thank you n advance.
