Question about Philips 27PT543S 27" TV

1 Answer

Problems with sound, video , and powering on

When the power is turned on I would hear sound and then the screen would go off but the power light will still be on. I would the turn off and on again. Doing this four or five times would return sound and picture to normal. The symptoms got progressively worse wher I was turning the set off and on with the remote 30-40 times to correct the screen. After about 2 monts it then started clicking in the beginning of the process. And at three months this no longer works. Now when you turn the T.V. on there is only a high pitch ping or clicking sound and the power light does not come on at all.

This could have started as a loose solder connection or a capacitor going bad inside the set. By now you probably have a shorted transistor and maybe a defective power IC as well. At this time of year when there are bargains to be had for new TV's, I would just replace it as the repair would likely be over $100.

Tv problems lg and vizeo


Power Issues Troubleshooting
*NOTE* LG & Vizio TVs must be plugged in for 5 minutes before it will turn on*
1. Inspect ALL Ribbons and connectors. Any tears or bad connections between boards must be replaced FIRST
2. If you have any of these boards, it should be the first board to be replaced
A) T-Con Board - Video Problems (No Video with standby light on, audio but no video, grainy, distorted, or color problems in screen)
B) X or Y Buffer Board (Plasma TVs only) - Standby light is on but no power
C) Backlight Inverter / LED Driver - No Video with standby light on
3. Main Video Board
- Standby light is on but no power
- Either video or audio does not work (if no T-Con in TV. If audio but no video it is T-Con)
4. Power Board - No power AND standby light does NOT turn on. If standby light is on try other boards above
5. Panel - No power, distorted picture, lines, slow motion, half screen, faded in / out. Panel problems are usually not worth replacing the panel.

My toshiba at200 table 10.1 wont turn on


1. When you press the power button to turn it on, do you see any thing on screen, like the toshiba boot up screen or something like that. Or is it completely blank (black color) always.

2. Can you see a faint image of your desktop (try to see it in dark place with flash light). This is important to confirm.

3. Also, when you press power button, do you see the LED lights on laptop blinking or solid green (which ones are in blinking/solid) and do hear any sound ? Or do you feel that your laptop doesnt even try to boot.

4. Can you hear any Beeps when you try to turn on the computer. If yes, what is the sequence of those beeps.

Screen blank


I believe the sound you hear is simple static, if there are no power buttons showering where they should, look for a bad power adapter, make sure it is on, see a light? next check your battery.
Now past this you have a problem inside of your laptop, as in a bad motherboard or bad video chip....

While the PS3 is off (red solid light) hold down the power button until you hear the SECOND beep, quickly release the power button.

Let me know what happens.
