  1. Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

Use a hair dryer on the back right side of unit. Humidity sensor may be causing the unit to stay off. The hair dryer may also remove dust causing a false humidity detection

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.

Four blinks to Sony CRT based standard televisions are not due the fault to any fan, as there is no fan inside any CRT based Sony TVs. Four blinks denotes this. Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505 Check for this fault. If you wish to get more http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by its left side bar, or view it in Timslide option.

Sony KV 27S66 - When power button is pushed the "click" is heard then the set shuts off and the stand by light in front flashes. Is this the main power supply board that has gone out?

Hello

Blinking of standby light in Sony sets anre fault indications. There will be a specific number of blinks for each fault, from which we can understand the actual fault section inside your Tv. Count the number of blinks by Switch On and Switch Off by its front panel ON-Off switch for atleast 3 times, and confirm it. Just send me the exact number of blinks through Fixya. I'll assist you Ok.

Sony Wega Kv-36XBR250 screen blinking

I have seen this flashing before, this could be an indication that the picture tube is weak, what happens is that if the white balance is off there is a circuit called akb it monitors the kathode of each gun and if they are not in balance it will attempt to balance it out. if it can't the picture will begin to flash, sometimes in some models the power light will blink 5 times. On some models the power light will only flash if the tv gives up trying to compinsate for white balance and shuts off compeletely. If you see the tv shutting off with 5 blinks then you know for sure it is time for a new set.

Sony shuts off after being turned on, stand by/timer light blinks

The blinking should be in a pattern of a count, pause, count. That is an indication of the problem circuit. Can you post that count please? That info will allow me to give you possible defective parts and costs for the repair.

Thanks,
Dan
