Question about Sony KV-36XBR400 36" TV

1 Answer

HV Sound no Picture

Problem began one month ago (and shortly after finishing a custom stand for it). Turn TV on, sound, no picture. Initially switching power on and off 10 or 15 times and picture would appear. As problem progressed had to operate for an hour or 2 with no picture then cycle power once to get picture.

Isolated to HV transformer. 30 seconds with hair dryer 3 inches from side of transformer before turning on works every time.

TV will now shut off and flash 6 on the LED after operating for a few hours (getting shorter) If I switch on again within about a minute or two I will have picture. If I wait more than a few minutes, the hair dryer is needed again.

Anyone seen this? Is the transformer replaceable? I’m qualified and competent with a soldering iron. Where can I order the transformer?

Re: HV Sound no Picture

Sounds as though there is an intermitant, heat-related problem with the HV transformer. You can order this at a tv parts shop or from Sony (probably more expensive) the part number should be on the part or on a schematic. If not, the parts dealer can look it up from the model number.

Good luck! :)

TV has no picture, but sound works fine

Are you using the AV input for the XBox or other cable? If you use AV, then use the same input that the Xbox does not show picture, plug in a DVD and see if it works. If it does not have a picture, so 100% your TV has problem.

1999 sony trinitron color tv -no picture-no sound.

Hello c_car,

What is happening is that the Shutdown Circuit is turning the TV off due to excessive current flow. The excessive current flow is most likely the result of a problem in the HV (High Voltage) section of your TV. This could mean that the Horizontal Output Transistor or the Integrated High Voltage Transformer has malfunctioned (developed a short circuit). I would advise that you let a qualified TV technician work on the set due to the nature of this problem.

I hope this helps,

Thank you,

I have seen this problem before.

The problem turned out to be caused by a poor solder joint on R530. This is in the HV
sensing circuit and is associated with IC501/ comparator. The resistor was replaced for
good measure and proper operation restored.

Stopped working and squealing sound

Your set is shorted circuit condition. The power supply is making the noise. Unfortunately almost any of the hi current circuits will do this. If picture went out 1st look for video or hi voltage problems.

No pic or sound but gets power

The power supply may have failed. Also, it is possible that there is a failure in the HV section.

You will have to take the set in for an estimate. This is something that I doubt you can fix yourself at home. The set will require troubleshooting by an experienced tech.

No picture but sound is perfect

Sounds like the video output has a problem. Maybe missing the 200 volts from the High voltage transformer. The vertical circuit may have an issue. Either way it's hard to diagnose without looking at it. If you need a technician contact JVC online at: Good Luck
