After reset by remote for sony crt 34 inches tv, the picture became small now, need to fix it, for model kv-lx34m50. color quality has changed and no good quality like before. what to do to solve it

A reset won't fix this. The standby light should be blinking a repeated count with a 3 second pause inbetween. Post that count here. That will indicate the circuit/condition that is preventing the set from turning on.

Thanks,
Dan

Its not matter of service code only. You also need service data to fix it. But question is, how data is being corrupted? It seems hardware failure in your TV set.

on your sony tv (not cable) remote - hit the MENU button, then scroll right to SETUP on the screen - the first choice - caption vision - is probably set on a close caption or text - change it to off. i had the same problem - would pop up occasionally and only on certain screens. this fixed it. hope it works for you.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.
