sounds like the LSB is defective as that controls all the high voltage and deflection circuits. If you go to the following link and leave them a email with your model number they should have a LSB board for your model.

How do I fix my KDL55HX750? It will not turn on. No sound or picture. Just 3 blinking red lights. What should I do next?!?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Blinking codes details of many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

My Sony TV that is only 9 months old will not turn on the Red LED is blinking 8 times and there is a pause and it blinks 8 more times. Thanks


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.
If you're sound in electronic, and wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.
It sounds that the TV is mew one, and come under warranty period. If so, it will be best to get it repaired by the authorized service center for Sony.

Hi,
5 times blinks shows incorrect white balance (AKB) error. TV needs Screen Volts (G2) adjustment.
Take off lower front panel, find Focus Block that has 6 control knobs, adjust Screen volts of each CRT (red-green-blue) and problem will be solved.
Be Careful while working in TV.
Let me know if you have further question.
Thanks.

Won't turn on


Although the other response is in much better technical lingo, it sounds to me like the television had a high voltage arc which I have seen on quite a few of the sony big screens lately. Usually, it causes a part on the circuit board, (one of many that were listed on prev. solver's list) to fail. This causes a delimma for the repairman, because when they find the bad part and replace it, sometimes it will pop again causing repeat failure of boards and/or parts on the board. Sony is known for having bad tubes on their projection sets, and it can be a difficult repair even for a trained tech. I suggest calling a sony service center in your area, and get an accurate estimate before deciding if replacing the set is the best idea. Hope this is helpful input, Russmann.

Check your CRT boards on the end of the tubes for burn spots, and burnt components, check the resistors to make sure they are not shorted, burnt, and they read the correct resistance. Check the diodes to make sure they conduct in one direction only and are not shorted or open.
