Question about Panasonic Televison & Video

1 Answer

During a storm a bit ago all the HDMI ports stopped working I am looking to fix them finally and wondering if anyone can help w a part # and instructions.

I called sears and they are unable to locate the model # of my TV. Im guessing I can just change part myself (or husband haha) and save $. But looking for what part # I should be buying. Husband has tried new cables all HDMI ports and none of them work. We had to more the apple box upstairs since it only works w HDMI and use component cables for other stuff. Well PS4 is HDMI only as well so it looks like I need to get this fixed or get a new TV. Thanks so much any help appreciated!

A basic understanding of electronics helps. I would look inside on the board and follow the traces from the hdmi back to the chip that feeds it. It would likely be an ic that has a voltage regulator in it as well as something to convert the serial port data. Write down the numbers on the chip and go to or phone an electronics parts supplier in your area and they will consult a cross reference manual to see if an after market version of the chip exists. If not they will order the original. Once you have the chip, you will need a decent soldering station ($100 or so) and a solder sucker. The solder sucker is used to desolder the chip or component slowly. Don\'t overheat the component but desolder as far as you can. then wiggle each leg one at a time until it breaks the remaining solder. If it does not wiggle off heat it again then wiggle it. Once all unsoldered gently pry out. (any other attempt to desolder without a solder sucker will damage the printed circuit traces) Before removing the ic verify which pin is pin 1. It may be printed on the board or a corner of the chip is marked somehow. Place the new chip in with pin 1 in the proper location. Use hitech solder that is hollow and contains flux on the inside to resolder. If the wrong solder is used the flux may attack the components and it will fail within a year (plus or minus). I would suggest finding someone who already does some electronics to assist you or to do the whole job.

Have you checked the fuse? If the fuse is good you have a problem with the power supply which can be repaired. You would need a service manual for the power supply. But that would be a lot cheaper than having it repaired by a shop. Power supply problems usually run about 400 to 600 in a repair shop. When often it is a 20.00 part. If I can assist you further please let me know.

SOURCE: Toshiba 52hm84 DLP-HDMI Component has been compromised?

This is a wild guess, but I believe that you are being **** by the movie industry. The HDMI protocol includes a form of DRM (Digital Rights Management) for high resolution content called: High Bandwidth Digital Content Protection Basically this means that the media (disk or broadcast) instructs the player (in your case the cable box) to insist that any downstream devices (your TV) is industry and DRM compliant. Specifically this evil protection scheme is designed to plug the analog hole and make it impossible for you to record or copy the movie by using an analog output from your TV. This even restricts the size of the TV you can play the movie on, thus preventing pubs and bars from displaying the content on big screen TVs without paying royalties. The message means that the manufacturer of your TV has refused to toe the industry line. 1984 Anyone ? Martin

It sounds like the 3 "GUNS" are not aligned.
One the controls at the bottom, left hand side You will see an arrow pointing to the first 2 on the left.
That will allow you to scroll down the list of options until you see....CONVERGANCE!
make the red gun center by using the up/down arrows on right. Then add the next 2 until you see a white X or cross.
Thats it!

If sound on one HDMI and not the others---all three should go to the same board--either something is not connected inside or the replacement board is the issue---Samsung is known for making boards with the same part number on them that from week to week have different features or do not have certain features.

Try to trace where the working input goes and if to same board as other two you know what to suspect.

HDMI PORTS NOT WORKING


Try visually inspecting HDMI’s that are not working. Occasionally, pins on HDMI connectors are getting bent or pushed-in. If you can spot the damage, fix would be to replace HDMI connectors. If connector are not damaged, then main unit of the TV has to be replaced.

It may be a problem with the DVRs. You can rule that out by connecting a different HDMI TV to one of the DVRs.

HDMI ports do not work after lightning storm


Probably not, but your insurance should pay if you have a renter or homeowner policy.

It is possible that the HDMI ports are blown. The work through their own circuit area in the TV set. This is a particularly complex area.

You will have to send the set to the authorized service rep for an estimate. See if your home insurance plan will cover for this type of thing. Some types of home policies will cover for this type of thing. The cost of servicing your set may be expensive. Damage from a lightning strike will not normaly be covered by warranty.
