Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Please help... The red crosses refuse to move left or right, both. They move up and down just fine.  Is there an easy test I can perform to see if it is in fact the resistor?  How difficult is the resistor relacement as compared to the IC replacement? Will I need to solder etc...?

Yes you will need to solder in the resistors. How you check them is by unsoldering one side of the resistor and lifting it out of circuit and checking it for resistance. Ifd its open you will get no reading. If it reads less or more than 5 % of its rating it will need to be changed as well as it can weaken the Ics and they can end up failing if a weak resistor is left in circuit.

I have a sharp aquos tv model lc-32m400x. When i turn the power on via button at the back the green light comes on for about 10secs then turns to red and flashes about every 11/2 - 2secs. Any ideas.


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. In some cases, the remote control might need to clean.

I have checked cables and different methods of connecting, but the white and red audio out of my PVR appear to have stopped putting out sound.


Go through the setup of the PVR and check the sound settings. It sounds like it's only producing digital audio, that's why it works with HDMI but you want analog, so set the audio to stereo, or try every setting to see what works!

One thing is that unless it is usb you should always have the devices powered DOWN before connecting them via" wire electric data cables". it only takes 3 static volts of electricity to damage a circuit board. when you zap you buddy when you wear sox its 20 to 30,000 volts of static electricity so 3 volts would not be known let alone felt or seen. Power down and you will be well not you .
