The 4 blinks usually mean a vertical deflection problem. If you can solder you should be able to repair this yourself. Let me know if you wish to attempt the repair and I'll provide more details and instructions.

SOURCE: Sony Trinitron wont power up
the red light flashing tells you and a service person why the tv will not power up . if you have test equipment to work on electronic equipment then we can move forward if not ,your tv will need parts replaced or board replaced . you dont have a failure that you can change a setting or push a reset button to repair . you will need to get in there with equipment inject signals,look at waveforms ,and check voltages . and know what you are doing with the information you gather ...the other answer you need to send it out for repair .... most repairs on this set will run 100.00-200.00 for common problems .........Please if this answer helped , please rate this 3 or 4 stars . and keep me in the paid answer department . A 1 or 2 may knock me down into the unpaid ranks. Thanks Cactus Bob .

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.
