If there is no power LED lights up at its front panel, it indicates that the main power supply regulator board inside the TV has the fault. It do not works at all, or it do not get the AC mains power into it to work.
If the power LED at its front panel is lit, and the set do not power up by pressing the power button at the remote control; it is the symptom of a faulty main board.
Fault to the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Sony klv 32s530a lcd tv program sound ok no pitcure but backlight ok


unplug everything and test one input device at a time (ie, game console, computer, tv, cable, etc) and select the appropriate input for whatever you plug in.

could be the device being plugged in and not the tv at all.

Also, do you get a menu when you press the menu button on the side of the television? If so, true, backlight could be okay.

If all this fails, turn off and unplug tv, remove rear panel, and, one at a time, unplug and plug in every connector jack (cables) that you can find on the back of the unit. check for loose jacks/connectors, smell see if anything smells burnt.

Lastly, try not to electrocute yourself when inside the tv.

Screen was pushed in, takin covering/surround off and fixed screen, replaced covering/surround but colour not right, can see rainbow effect on pitcure. is there a certain way screen must go to transform...


If this tv has a feature called magic focus or perfect focus which is a button inside door that flips down on the front, then it has sensors on the inside of the screen. When it was pushed in, these were probably messed up and will cause a poor picture. It may be difficult to get those realigned. Magic focus will not work right until they are realigned.

Whilst watching tv after 10 to 15 min screen goes blank but sound ok ,when u turn tv off then back on u get pitcure for about 10 minthen goes off again


I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

Is the TV losing power to it when you shut it off? This would be the only way that I can see it forgetting channel memory when off.
