Question about Panasonic PT-40LC12 40" Rear Projection HDTV

1 Answer

HEY ctf1800!! Green light blinking - need more clear description of what to do..(please :-)

I saw the post from ctf1800 and really need some clarification, hopefully you can help: ------------------------- Comment by ctf1800, posted on Jan 28, 2008 Found that the thermistor/temp measuring device is suspect, no resistance...ETC
-------------------------

However, i am a bit confused. you posted the link: http://www.goodmans.net/get_item_th-tf117c_thermal-fuse-117-degrees-celsius.htm
Which brings up a fuse...but then below you said "i purchased a NTE8115"...

Which fuse do you suggest to buy?

What is more confusing is what you wrote after that...

"remove the back cover and measure for continuity across the thermal fuse
above the lamp housing.
if open jump it wth a 5 amp fuse, be sure to close the safety switch with
the small blue lever then try to power on.
If comes on ok you will need to replace the entire ballast assembly to get
that fuse.
Panasonic does not have a part number for just the fuse on the PT40LC
series.
It is possible to cut off the fuse and replace with another but dont solder"


Basically, I have the problem where my "on light" just blinks green...repetitively without stopping or changing colors, or turning solid...it just keeps blinking green.

from the sounds of the similar posts, i need to change out a fuse. but you listed three fuses in the top part of your post, then you wrote the part in hte lower section of your post (which i pasted above) about there not being a fuse you can buy, that you need to buy the entire ballast assembly.

So, do you know exactly what i should be buying and doing to fix my unit? I realllllllllly appreciate any help you can provide.

Also, I DID NOT replace my lamp yet. i searched the internet and came across several people here that seem to have the similar problem and the lamp does not fix it.

Thank you!

    ok, so the fuse within the ballast assembly is the generic fuse "NTE8115". so i can just cut it out, put that one in there by splicing (not soldering) and then i'm done...right?



    anything else i should know?



    Thank you.

You can buy a generic fuse which is what those are.

One of my members has an HP Deskjet 3650 and it


See this article to resolve the blinking lights. Then see this article and possibly this one to clear the print queue. You may have to cancel an active print job to remove it, or reboot the computer. Here is the home support page for that model printer, should anyone have further questions or need more information.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

HP 1220C. I had a paper jam, removed the back and cleared the jam. The green light and yellow light are still flasing. I cleared all print jobs from the que, unpluged the printer and repluged, restarted,...


Make sure when you reset it you also remove the data cable from the printer, then unplug, wait a few minutes, or up to 30 minutes, then reconnect and restart.
Also see possibly helpful links here and here.

Mitsubishi wd52725 green blinking light


Haven't done anything as of yet. I saw many posts that stated it costs between 800 & 1500 to fix the problem with no guarantees on the repair or how long the repair would last. Still weighing my options.

Mitsubishi WS55909 blinking green light


how long was it blinking. after a complete loss of power the green light will blink on power up as it is resetting itself. It says in the manual that it should take about a minute. Over the last two days I've have to reset it several time both by unplugging it and using the manual reset button and it has taken about five minutes for the blinking green light to clear.

Blinking green light will not power up


My WS-55859, Did the same thing. Power went out, when it came back on the green light in front of TV would blink, but TV would not power on. Did some googling and saw multiple posts for "blinking Green light" or "Blinking Green light of death". Most of the posts pointed to replacing capacitors on DM Power board. I followed the direction and it worked great. Note the TV shop guy who did the soldering for me said the capacitors "looked fine" and they were not the problem. I couldn't tell the difference between a good or bad capacitor, so I asked him to swap them anyway. He did, I plugged the board back in, buttoned up the back of the TV. After 60 seconds Green light stopped and I started watching TV again... Here is the link to the best instructions I found (http://hdtvoice.com/voice/showthread.php?t=32186).

Mitsubishi model No. WS-55807 - In need of schematic please


I have a WS-55807 that will not power up. When the power button is pressed I hear a click from the back of the set, the timer light comes on and 3 seconds later I hear a click from the back of the set, and the timer light goes off. I started checking power to the unit with a voltmeter. For those intersted I have attached scematics: I verified that the PCB main fuse is good and there is 120V at point PT. 9f453c1.jpg
From what I can tell is happening, the power button is pressed and the P-ON transistor is given a signal to conduct which causes K9A50 to close. K9A50 opens after about 3 seconds.

I am looking for other troubleshootinng steps. I have checked fuses F9A01 and F9A06, both are good. What are some other things to check for? Where does the P-ON signal come from?

In the switched supplies regulator circuitry I found fuses F9A04 and F9A05 blown (denoted by red lines thru components). I jumpered around F9A04 and F9A05 with good 5A fuses and the TV powered on. However when the set was plugged into an outlet there was a huge power draw (sparks from the outlet).
1c13374.jpg
After jumpering around the blown fuses, the TV stayed powered on for about 30 sec and then powered down. I pressed the power button a few more times and the same result. The TV stayed on for only 30 sec.

I pulled the middle PCB whichs holds these circuits and I found the
D9A60 diode open and IC8C02, one of the convergence IC's fried. I don't know if these were like this before or after jumpering.

I replaced all bad components and I am back to square one. The K9A50 relay stays closed for 3 sec and the set does not power on any further.
Comment by TV_ITGuy, posted on Dec 19, 2007 Thanks for the advice ctf1800. I have read several posts that speak of the DM unit. I have looked in the back of my set and the DM unit is not in the location shown in the pictures. dcb8806.jpg
As I hope you can see in this picture, there is no DM unit to the far left, just open space. Also the service manual for the V17 chasiss does not speak of a DM module.

I checked the reisitors on the output of IC8C02 which are a couple of 3.9 ohm resistors in parallel. When I test them I get approximately 1.9 ohms, which is what it should be with them being in parallel.

Please let me know if I am off base on any of this. Thanks Comment by TV_ITGuy, posted on Dec 19, 2007 Also, I have replaced both of the Convergence IC's when I replaced the fuses and diode. postsolution.gif Post Solution addwq.gif Work Queue -->sameproblem.gif Have the same problem? --> Have the same problem?

first off you should replace both convergance IC and check the resisters coming off the output if any of the resisters are bad it will trash the ic on trying to power up.
i would also replace the caps in the DM section

Comment by ctf1800, posted on Dec 20, 2007 there are six fusible return resistors ranging from 1.5, 1.8, 2.2, 2.7, 3.3, 3.9 Ohms. I would lift one side of the resister out.
check for any caps that look puffy and check the horz. out put transistor.

Status light is red


Hi, Based on your post/description, the Siemens AP/Router is at fault. This could have been brought about by lightning, power surge, plain hardware failure or system/software error. The red status light - on indicates an error (on the firmware)(blinking during start-up or when firmware is being downloaded/updated); WAN light blinking green - data transmission to/from your ISP (it is also possible that the router is trying to download corrective software or firmware update). Suggest you let it run for sometime just in case it is really downloading/upgrading firmware. If full reset of the router doesn't correct the problem, you may have to replace the unit. Good luck and kind regards.
