Wires going into the flyback are not removable but are integral to the flyback. The three wires comming out the flyback are the thick red one (anode button) which attaches to the tube is removed by pinching the button to release the clips on the tube. The other wire probably white is removed by unsoldering it from the small board on the neck of the tube and the 3rd and last wire is probably black, this is the one you may have your issue. To remove this wire, you must disassemble the tube socket..look for two tabs..pry open gently and seperate. Then with a small jewelers you'll be able to release the black wire..hope this helps.

    Wow....Yes your replacement flyback should have 3 wires comming out of it that are part of the flyback...May I ask, where did you get this replacement board/flyback, can you tell if the wires were cutoff. I would call and let them know that the wires are missing. Sorry for additional questions, but have been repairing tv's for over 30yrs. and have never experienced missing flyback wires...have certainly seen them cut. Some Flybacks for Projection type tvs have removeable wires....but your tv is a crt/tube type which should have the three wires as discussed. Good Luck

Hello tellis356,

He replaced the Integrated High Voltage Transformer (IHVT) (I so hate the term flyback even though it is descriptive of the function of the component). However he may have only solved part of the problem. My next question is did he perform a diagnostic on the CRT (picture tube)? It may well be the CRT, but I would first suggest that you have the repairman check the voltage and signal levels in the horizontal section of the TV and check the video signal and voltage levels at the output of the Video processor to the CRT socket board. Then after these are tested and proven to be within specifications, then run a diagnostic on the CRT using a CRT test set. This way he'll know for sure if the problem is in the circuitry or the CRT.

I am suspecting that the first trouble you experienced was the set was completely out? If so that is why he may have replaced the IHVT. He should have also replaced the Horizontal Output Transistor because it is in series with the IHVT and would have taken some of the damage that the IHVT would have sustained. So having him check that too would not be out of sorts.


I hope this helps,

Thank you,

You have a bad MCZ. Try taking a blow dryer to the right side of the TV to see if this fixes the problem.

You will have to find these and replace them both on the board to the most left of the T.V. There are two of them. The one closest to the back of the T.V. is probably the problem.

Sony TV Error Code - Seven Blinks


You try to turn on your Sony TV and nothing happens. Then you notice that the standby light is blinking. Counting determines that it is seven blinks about a second apart followed by about a three second pause. <br /><br />Your problem is that the B+ (high voltage) is over the normal maximum value. You have a problem in the <a href="/#"><span>power</span></a> supply regulation and horizontal circuit. It more than likely is a bad solder joint. Solder all the connections in the high voltage area. This is the area around the flyback transformer.<br /><br />The flyback looks like a can and is at the rear of the TV in a <a href="/#"><span>Sony</span></a>. It has large red rubber wires comming out of it. One of the wires is connected to the CRT near the top. <br /><br />If this does not solve the problem I have a tip at <a href="http://www.fixya.com/support/r4916851-diagnosing_repair_tv_high_voltage">http://www.fixya.com/support/r4916851-diagnosing_repair_tv_high_voltage</a> which should be helpful to troubleshoot the problem.<br /><br />If you cannot locate the problem or do not have the necessary troubleshooting skills a better plan may be to <a href="/#"><span>purchase</span></a> a new circuit board.<br /><br />Fortunately these days circuit boards are not that expensive. I would recommend replacing the defective board. The board with all the power supplies in a Sony is generally the "A" board and contains the High Voltage power supply. <br /><br />Two of the best places to get the board are <a href="http://www.encompass.com/">http://www.encompass.com</a> or <a href="http://www.shopjimmy.com/">http://www.shopjimmy.com</a> . <a href="/#"><span>Prices</span></a> are similar but both sites are trustworthy and will allow you to return the boards if they are not the problem. <br /><br />If you haven't replaced a circuit board I have a tip at <a href="http://www.fixya.com/support/r6981868-replace_circuit_board_in_modern_tvs">http://www.fixya.com/support/r6981868-replace_circuit_board_in_modern_tvs</a> which explains the process and should be helpful to complete the repair.<br /><br />Thanks for using FixYa and for the great rating.

you will need two STK392-560 Convergence ICs and possibly a couple 3.5amp pico fuses. also if the small wire borke off inside the flyback you will need to replace the flyback as thats the wire for the focus control block. You can get the replacement parts at the following link with free installation instructions.
