Panasonic TCP42C2 42 in TV - Answered Questions & Fixed issues

You will need the remote for this function.

These 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. http://electronicshelponline.blogspot.com/ http://electro-medical.blogspot.com/ Blinking codes details of many popular brand TVs are given. Surf the site with patience.

maybe this can help.

This will depend on what type of wall you are fixing it to. It's a pretty big TV so for a solid timber brick or cement block wall I would suggest M5 or M6 x 50mm
If it's a hollow stud-work wall you will need to use specialist hollow wall fixings such as toggle bolts. again M5 or M6 thickness would be appropriate but you would be well advised to try to screw into the actual stud-work rather than just rely on plasterboard to support such a weight. You can buy an electronic stud detecting tool from DIY stores relatively cheaply.

It sounds that the main board is faulty. I2C bus short. Visit the site named 'Electro-help' for more details. Click this link. View it in 'Flip card' option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. There are more than 900 posts to different brand TVs now. Blinking codes and fault descriptions are given in detail in one among the posts.

When you say 'closed captions' I assume these can be seen but cannot be selected. Kindly look through the operation manual and check whether such features are there in the TV.

It is a common thing that all the buttons of a universal remote control might not work, as it meant to be. Try an other code. If this too won't help you, there is no other way than buy a new original remote control for your Panasonic TV. You can buy in from the authorized service center for Panasonic at your town. Just give them the exact model number to your TV. They will provide you the original one.

Using a box for signal and hooked via component or composite(rear jacks)?Got sound when playing a DVD etc via rear inputs?

Sounds like you have a bad joint on the tv circuit board somewhere.There is another thing it could be if you have a scart lead connected. Pull it out and check to make sure none of the pins are dissapearing inside the plug. Sometimes they slip inside. Check both ends of the lead.

If you are using a cable box or other device upstream, look into it's volume. Typically source units would like to be 30 to to% volume, with the tv or stereo being the final control. What happens is the source volume gets turned too low, and then the final unit (tv or stereo) has to have so much volume to hear anything, distortion and poor sound result. Start with both midway and you should be good to go. This presumes that you toggled any buttons that said mute or attenuate...

HI, to fix this problem you will need to know how to use a meter to test or read a capacitor..

Hi, Connect your multimeter probes to your multimeter. Observe the correct polarity. The red probe is the positive one, and the banana jack at its end is plugged into the red plug on the multimeter. The black probe is the negative or common probe and its banana jack is plugged into the black plug on the multimeter.

Set your multimeter function by turning the function knob or selecting a function button to measure voltage. Select either an alternating current (AC) or direct current (DC) voltage, depending on the output of your specific power supply. Most household power supplies produce a DC voltage.

Unplug the electrical device and remove any housing on the electrical appliance in order to gain access to the power supply. Being careful not to touch any of the electrical circuits, turn on the electrical device, which will also turn on the device's power supply. Make sure it is plugged into the right power source. Most household electrical appliances, other than dryers and ranges, operate by plugging into a typical 120 volt house circuit.

Touch the multimeter probes to the power supply output terminals. Make sure your hands stay on the insulated parts of the probes. Observe the correct polarity. Power supply output terminals are usually marked with a positive (+) sign and a negative (-) sign. Touch the red probe to the positive terminal and the black probe to the negative terminal.

Read the multimeter display for the power supply's output voltage.

After determining the voltage, remove the probes and turn off the multimeter. Unplug the electrical device and put the housing back on.

Static Electricity Warning
Some components on the power supply are CMOS integrated circuits and are therefore sensitive to static electricity. Before touching the circuit board, I make sure the TV is unplugged. Then, I touch a piece of metal on the back of the TV that is grounded, i.e. part of the metal frame or one of the mounting screws or mounting posts of the power supply board. This will dissipate any stored static electricity by the body and discharge it to ground. CAREFUL!!! This should only be done with the TV turned off and NOT plugged in. Otherwise, one might touch something with HIGH VOLTAGE and receive an electrical shock. In particular, stay away from the large heat sinks with the yellow stickers on them indicating high voltage.

Overview
The power supply is the large circuit board in the middle of the TV. It has many transformers, large capacitors, and a couple IC's. There are eight connectors attaching the power supply to the other circuit boards on the TV. Looking closer, one can see that the power supply(Model#:PSPF651B01A) is manufactured by Samsung, as is the plasma screen itself. The supply provides about ten different voltages; 190V, -180V, 60V, etc for the plasma screen as well as 3.3V, 5V, and 12V for the logic and digital electronics.

The power supply circuit board contains a wealth of information including its part number and a table of the different voltages it produces along their signal names(Va, Vscan, Vstb, etc). Test points for all these voltages exist on the left side of the board(looking at the power supply as it is mounted to the back of the television).

How to test
I used a multimeter to probe the voltages at the testpoints with the TV turned on. BE CAREFUL!!!! This is of course highly dangerous as HIGH VOLTAGES occur on the power supply and the TV was not meant to be run with the back off. Touching certain points on the power supply while it is powered can KILL YOU!!!! To be safe, don't touch ANYTHING inside the TV whilst it is plugged in. In fact, if you do not know what you are doing, just stop here. No point killing yourself over a stupid TV.

If you dare....
The RTN node (seen on the silkscreen at the top left connector(and others) ) is basically the common grounding point and is connected to Earth ground, the shiny metal backing of the plasma screen, and all the metal mounting pegs that the power supply is mounted to. The black or negative lead of your multimeter should be attached to this point. I just stuck the black probe into one of the mounting studs and let it hang there (out of the way) so I could probe using the other(red) lead of the multimeter with one hand.

Start off with the TV unplugged and turned off. Attach the negative or black lead of the multimeter to any mounting stud near the power supply board. Now plug in the TV and make sure nothing explodes. Now turn on the TV with the remote control and again make sure nothing explodes. Is the screen blank? If so, good. You'll be able to probe the test points on the power supply to determine which voltage is not being produced. In my case, it was Va which is supposed to be 60V. Make sure to make a good contact between the testpoint and the multimeter probe. If the contact is poor, the voltage readout may look as though it is fluctuating between the spec'd voltage and some lower voltage. For example, if the spec'd voltage is 180v, not pressing hard enough to connect the probe and the testpoint may result in a readout that wanders between 180v and 50v.

If all the voltages are being supplied and withing spec (as shown on the power supply's silkscreened voltage table shown in the fourth picture below), your power supply is most likely functioning correctly. Your problem may lie in a different area. Numerous people have mentioned a problem with their Y-Buffer, the circuit boards flanking the left and right sides of the plasma screen. Specifically, whitby905 (see the comments section) has found that the lower left Y-Buffer board was contacting the metal plasma screen backing and had shorted out. If your power supply checks out, look and smell for any indication that any of the Y-Buffers have shorted to the case. You may have to remove them and look on the back for shorted solder points. I don't have any pictures of this situation besides the one from whitby905 in the comments section.

My problem was with the Va voltage of the power supply so I will continue discussing it in the next section "Debugging on the Bench."

Hi,You can ask further question here about 7 times blinking problem as we were in chat session and lost the connection.Thanks.

Metric M5 or M6, you can get them from HD, or Lowe's for about 25 cents each. The length will depend on the thickness of the bracket and the depth of the screw's holes.
When you buy the mounting bracket, it should come with a bag of Metric screws for you to use for mounting.

Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.

Count the number times the red light blinks this is an indication of the error code as to what the probem is, if it blinks 10 times then this is a power supply failure.

The tv now,it is take about 2 or 3 mins for the picture to show up or no power LED light indication to the tv at all or power LED light indication it is flashing now?This problems it is the tv power supply board problems.That the board where the tv power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv power supply board for the replacement.

I have a Comcast HD DVR set top box and had to enable closed captioning from the Set Top Box, not from the TV
Hope it helps
