SOURCE: humming noise

There are only two moving parts in this set. The fans and the color wheel. Typically when the color wheel starts to break or go on the fritz, the tv stops working. Count your blessings you've still got the picture. Open the back and turn the tv on. The color wheel is located on the optics block tray. The fans are very visible with the back off. Stop the fan for a second and see if the sound goes away. If not, you might want to start looking around for a replacement color wheel. Rivervalleyelectronics.net is a good place to start. Sometimes Discountmerchant.com carries them too. Be aware that there two different wheels available. If the fan is the culprit of your problem. Radioshack will likely have a replacement for you. If you need further help, post a comment or email me and I'll send you pictures of what to look for. Cfoley@hawaii.rr.com
Good luck.

Do the self check (hold menu and source for 5 seconds or more and release both) power light will blink a 2 digit error code like 1 blink, 2 blinks and pause and repeat it several times.

Panasonic PTL500 LCD HIDEF projector - Unit occasionally powered up briefly, lamp lit, then shut down, standby LED flashed orange/red. Sometimes lamp lit and sometimes not. Technician diagnosed bad ballast...


The bulb is a discharge type - it needs a very high tension to work. The role of the ballast board is to convert the low voltage DC current coming from the power source in a high tension DC current for the bulb. Unfortunately you were truly unlucky : when the ballast board died it sent a high tension surge thru the power source and from there at the other components on the mainboard - the processor couldn't handle it and got fried. So now when you try to start the projector this is what happens: the power source starts normally - the status light goes to green as it should; it functions normally so it powers the ballast board and the rest of the mainboard - the ballast works so the bulb lights up; the mainboard on the other hand remains dead because the processor is dead so no sustain signal is sent to the power source; without the sustain signal the power source goes, as it should , in an very normal stand-by - the status light goes to red.
The entire mainboard will have to be replaced - you can't replace just the processor, it's glued in there. This is going to be expensive so ask a quote before doing it.

Freezer wont freeze - digital display has no display at all -


Melanie--

Because this occurred as a result of a power outage, you need to check that the outlet is OK. Plug something in the outlet like a lamp and see that it works normally. If that is OK, check the display for a light bulb that is burned out--incandescant bulbs do that occasionally in a power outage. If it is an LCD or LED display, the power supply is bad on the display board. Is the motor humming and making normal noises?--and your freezer is just not cooling? If no motor noise, look for a reliable and trustworthy appliance repair person. If the damage is costly, try to pursue a claim with the power company.

I replaced the light bulb, now it displays -F6- and pushing any button causes a humming noise.


I left the unit unplugged over night, plugged it back in the next day and still had the same problem.

I have a 56" model that I have had a similar problem. My bulb burned out in <90 days. Warranty was 90 days on the bulb itself. When the TV picture goes out, the indicator LEDS blink on and off.

Here is what you have to determine:

1) First cover the left LED with a piece of paper so that you can't see it blinking. I don't know if your layout is the same as my TV. You may have to switch the paper blocking the LED.

2) Pay attention to the other LED and READ its' flashing code. In my case, the code was 2-3. It would flash 2 times, pause briefly, then flash 3 times. This meant code 23. That indicated the bulb was burned out.

3) If you look in the manual, It does have a code list of some sorts to tell you of the codes and their meanings. Hope this helps.
