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

1 Answer

TV will not power on

My TV no longer has a power button that can manually be pressed (button simply fell off, unsure of the cause of that), and I've had to use the remote to power it on and off for the past year.
Three weeks ago the remote became increasingly unresponsive and took upwards of 100 presses to power up the TV. I assumed this was a problem with the IR sensor on the TV and took it in for repairs.
Repairs cost me $170 and I got the TV back two days ago. They didn't replace the power button on the TV, but it seemed like the remote was once again working. That is, until this morning, when it suddenly is again completely unresponsive.
Power supply looks alright, fuses are all intact. I had a convergence issue, where I had to keep readjusting every few times I turned the TV on, but I'm assuming this is unrelated. Really I want to know what the problem could be. As far as I know, the IR sensor has been replaced. As I said before, my TV was working for two days after repairs and now is again unresponsive. I don't believe it's the remote, as I've tried three different ones (one that came with the TV and two universals which were programmed to it) and I keep getting the same results. The light won't power on or anything. It's as if the set is completely dead.

Magnavox tv when the power button is pressed the green light comes on but nothing else happens; there's no picture or sound or nothing; but the green light simply stays lit (no blinking).


Hello,

first, press the channel -/+ button on the TV. If that doesn't turn on the TV, then it means you have to replace the bulb of your TV. The bulb is most likely dead.

Replace the bulb and your TV should be restored.

Let me know if you need further assistance.

Regards.

Still getting "Projection lamp is nearing end of life"


KDF46E2000 - Change Lamp Warning - Reset

Bulb is most likely OK. Original bulb in Sony TV is Philips, label on bulb usually says Philips. Sony don't make bulbs. Sony Cost is usually 1.5 times other sources. Many shopping cart operations sell condemned, reject or poor quality electronic service items because cost of return and fooling with them is excessive. This is obvious and widespread with convergence ICs and other parts.

Lamp timer needs reset. This is usually an automatic function. TV detects Increased lamp current from previous failed bulb or weak bulb condition and resets automatically. TV must be unplugged for lamp replacement for this to work. Occasionally it must be reset manually, as below:

1. TV must be in standby mode. (Power off).
2. Press the following buttons on the Remote Commander within a
second of each other:
DISPLAY Channel 5 Volume + POWER .1. Access Service Adjustment Mode and select the Service Menu that
contains the Category with the Adjustment Item you want to change.
2. To change the Category, press 2 or 5 on the Remote Commander.
Note: Pressing 2 or 5 only changes the categories within the
Service Menu displayed. To change a Category on one of the other
Service Menus, press the JUMP button until the correct Service
Menu is displayed.
3. To change the Adjustment Item, press 1 or 4 on the Remote
Commander.
4. To change the Data Value, press 3 or 6 on the Remote
Commander.
Note: To go back to the last saved Data Value, press 0 then ENT
on the Remote Commander to read the memory.
5. To save the changes, press MUTING then ENT to write into
memory.
6. To exit service mode, turn the power off by pressing POWER .
Wait 2 minutes before restarting the set to allow the fans to
completely shut down or the Service Menu will appear on the screen.

My color is washed out and dim and the colors are wrong . Toshiba 65h83 projection hd tv


I don't know your model, therefore I will tell you genericaly what the problem may be.

There are many things that can cause this type of fault. The response of the video amplifier stages would have to be checked right up through to the output that drives the projection. it is also possible that there is a fault with the colour demodulator. If the set uses projection tubes it is possible that the tubes are weak, or there is dirt in the optics. Colour demodulation problems can also cause the colours to not be correct. Many models using tubes have an optical transparent cooling fluid in front of the tubes. This fluid may have to be changed.

Below is the website for the online manual which will give further instructions.  
http://dishnetwork.com/downloads/pdf/user_guides_and_manuals/remotes/6_3_RemoteManual.pdf

In looking at the manual no codes are given for the Coby brand TV. If the above process does not work, you'll have to call DishNetwork for further assistance. It may be that the remote will not work for your TV.

TV automatically turns magic focus mode on when the power button is pressed on the remote and even manually.


I have this problem starting today. Unfortunately, others who have fixed it have done the following.

* Unplug TV for hours and it worked

* Buying manual switch to the outlet or surge protector and switch power off that way.

It appears that I'm in no mood to spend hundreds to get this fixed for hundreds of dollars and just going the Radio Shack route of buying a switch which would probably be more of savings. But needless to say, I hope that is the only problem I have.
