Either the flyback or the HV splitter are the two most likely causes followed by one of the CRTs.

I have a Sony KDS-60A2020. TV went blank. No flashing lights. I have sound, but the screen is blank.


have you tried a power reset, unplug all components from the TV unplug it from the wall, then push and hold the power button for about 30 seconds, then plug all components back in, plug it into to wall then turn it on again.

Re:toshiba 55h70 tv i unplugged the tv to paint. when i plugged back in a wk later i have no picture or sound. nothing. can't access the menu - completely dark screen. the red lite "on" button...


I would check the fuse on the main board. Check the Capacitors on the Power Supply board. Seeing that you unplugged it and replugged it in you might have bad caps that were weak to begin with. Please learn how to safely work on a TV before attempting . Even when a tv is unplugged it has enough power to kill you. Discharge all Capacitors first. make sure its unplugged of course.

When i power up the tv, it immediately shuts off


How old is the tv? Sounds like the bulb. Is there any kind of lamp light indicator blinking or on? Averager life of a bulb is a few years, but could very well be shortened. Also check any surge protectors you might have. Maybe you recently had a surge and it needs to be reset. Last but not least try recycling the power on the tv. Unplug for 10 seconds then plug back in. happens a lot with cable boxes, recievers, and tv's from time to time.

Sound but no picture


Can you bring up the TV's onscreen menu at all when the sound is being heard? Are you hearing the sound from the TV's speakers or from external speakers like a surround setup? If the OSD is not showing up, then a video sustain boards appears to be corrupt and the TV would require service.

You still could at least try a power drain as this has rarely fixed this kind of issue:

1. Unplug the product's power cable so that the device is not grounded to the house. Do not simply turn off the power-bar if one is in use.
2. Press and hold in the products power button for 1 minute to release the retained electricity from the capacitors and circuit board.
3. Plug the product back into the wall outlet rather than a power-bar to rule it out of contributing to the problem and turn the device back on.

No Picture - Sound


I just had this problem fixed. In my case, it was because the insulation on the CRTs was cracked, and when it would warm up, the shielding would separate and would let 5000 volts arc across the main board. This, obviously, damaged the board. The tech didn't catch the arcing right away, so they replaced the main board twice before they used a high-temp RTV to patch the insulation.

The power-cycling was a result of the damaged board.

The point of this story is that the broken part may be a symptom of the real problem.

I hope this helps someone!

Humming from HLP5063WX TV and no color


Hi,

Initially, it would be suggested to try viewing a DVD or a VCR and determine if the humming sound & no color persists. If yes then conclusively, there is something wrong with the TV. If none, then the source of the humming sound would be the tuner section (internal to the TV) or your cable TV/aerial or your cable box/decoder.

If the humming sound and no color is present in either TV tuner/channel and with an external video source such as a DVD, then chances are that a large filter capacitor inside the TV needs to be replaced. It would probably be in the power supply section AC side.

If the humming sound and no color is present only on TV tuner/channel, you would have to check your TV signal source. If you are using an aerial, it may require re-orientation; if it were a basic cable, then you would need to consult with your cable provider; if you are using a cable box/decoder, then the problem could either be with the box/decoder or again your cable provider.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Bad electric shorting sound


when your tv starts making this kind of noises is ussually related to high voltage or a degraded component,If you are familiar with tv service you can remove the back and take a look just to check if you can see what is making the sound,sometimes you can see it if it is a degraded component cooking but if it is a heavy leakage of high voltage you will not see it and it can be dangerous to be even close to it,If you decide to go in to check you need to be very carefull ,I would suggest you call for assistance from a servicer if you are not too familiar with tv service.
