Sony trinitron kv35s26 no high voltage.

I tesed transistors and the small drive transformer they appear to be ok no ossilating ,does the ossilating signal come from the large IC 351 or is there a crystal somewhere on the board? i HAVE SOUND NO PICTURE OR HIGH VOLTAGE. SMALL LIGHT BLINKS CONTINUOUSLY. Thank you

Continuous blinking of standby light to Sony TVs indicates a fault with its II2C bus. Your set need an through checkup, which can only be done by any experienced service technician. Anyway, try the site linked here, and see is there any details which could help you. Do a search by entering the brand name to your device by its search box at top right of the display window, because, posts are not arranged in alphabetical order, but by brand name at first.

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.

Tube heater on a sony trinitron not working


They will usually be marked on the crt board socket on foil side with H, and another way to find them is follow them back to the high voltage transformer where the go---you will read a short and that is normal across them--I would bet if you locate you will find at the high voltage transformer or between it and the crt board broken connections or a open resistor----less than 20 of the connections between flyback (the transformer) and crt board---FYI the voltage across the two should be 6.3 volts AC.

You can trace it that way also if you locate the source. Worst case is no voltage at the source which would mean the transformer is bad but that is rare.

My 36xbr800 blinks six times then pauses then blinks six times, this is repeated......


Check the voltage input to horizontal output transformer [LOT]. Check the voltage at the collector point of the line drive transistor. If the line drive transformer primary gets open this type of fault mau occur. Also check the frequency ant the collector point of line drive transistor and the base point of line output transistor. It should be aroung 15625 Hz.
Check and replace the horizontal output transistor if needy. Replacing it is better. The horizontal output is not working or a short in secondary power supply of SMPS or lot secondary, is your problem

My triniton wega tv 32 inch flashes 5 times and i lose the picture then it comes back on lasts awhile then lose the picture again flashes 5 times again over and over


you can ensure the connection and Heater's voltage, start from Flyback transformer ( Heater Pin) to Heater of the CRT tube, whether exist and normal ( Include : check Resistor in Heater area), perhaps there is lost connection for a while and connect gain. There should be 5 Volt AC available. otherwise check the socket of CRT Tube, unplug and clean it. If there is any question you can ask me and clarification with detail result from my solution.

Standby light blinks you hear the contactor clicking in set, no audio and no video displayed. sony kv-36Hs500 only looking for response if this is free of charge


this symptom is usually caused by a breakdown in power supply circuit or it may also be caused by a breakdown in the horizontal deflection circuits which includes horizontal oscillator, pre drive or drive circuits, horizontal output transformer, horizontal output transistor and high voltage circuits (flyback transformer). pls observe precautions in dealing with this high voltage circuits and if so happen you are not inclined with this kind of work, it is better for you to bring it to a qualified technician to avoid accident. good luck!

The standby light flashes and the tv will not come on


check the power supply, its not giving out the required voltage output. if you cant repair a tv plse take it to a workshop, ask a technician to make sure that he checks the following components.
power diodes and transistor, fusable resistors around the power supply, and zener diodes.
he should make sure that an ht of 95-110 volts appears on the line transformer. later a transformer will produce various voltages to trigger other voltages to open up your tv. thanks

Sony trinitron tv loses picture but sound remains


Check solder joints on high voltage transformer and also on Q 502 transistor, this is a common problem for sony

KV-36XBR450, FD Trinitron WEGA


Hello maymet,

This sounds like the HV protection circuit is cutting off the TV due to a high current event in the set. This could be a problem in the High Voltage section of your TV (Horizontal output transistor, Integrated High Voltage Transformer, and y of the deflection components, and or the CRT in cases of shorts).

I would suggest that if you do not have a background in electronics, you should have an experienced TV technician troubleshoot and repair this problem.
This is due to the nature of the dangerous voltages that are present in the television.

I hope this helps,

Thank you,

No power.


Usually, in those Sony sets, a crack developes on a small transformer in the horizontal drive circuit, which causes the horizontal output transistor to short. This immediately shorts out the switching transistors in the power supply and blows the Sony 0.1 ohm resistor fuse. A shorted flyback (high voltage) transformer will also have the same result. The power supply does NOT need to be replaced. The parts should be replaced, the flyback checked and the board resoldered by a qualified tech familiar with Sony sets.

No picture and no sound,


Something shorted and shut your set down. Most likely the high voltage transformer shorted which also shorted the horizontal output transistor. Stargazer
