20 Most Recent Panasonic Viera TH-42PX80U Plasma TV Questions & Answers


I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)


2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.

It sound like you are using a component video connection to the TV, which is of variable specification. Try a different type of video feed from your Comcast box

Those 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.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

You have to programme the correct code for your TV into the Sky remote.

You can get these via "Sky Active" (if your box is connected to a phone line) or from the Sky website, or google search: "Sky remote codes".

However your sky remote wont necessarily control more recent televisions unless you have a REV8 remote control. You can check this by taking the battery cover off your remote and looking at the sticker inside. If it says RC1600/00 you're probably not going to be able to control your TV. REV4 and REV6 are more likely to work - but not guaranteed. If it says REV8, then you are probably not using the correct code or you're not programming the remote correctly.

If you have REV8, the correct code for your TV (according to Sky) is: 0678 or 1678 or 0254

Sky remote code finder page is here: http://sky.uebv.com/

There are 2-3 z sustain boards at the bottom of the tv. reseat the ribbon cables first and ten if it does not change replace the board.

A black and white picture suggests you are trying to use a composite video input but the TV may be NTSC format while your game is PAL, or the other way round. Use a game with the correct format or use the separate RED, GREEN & BLUE inputs (may require a different type of lead).

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Does it turn the TV on and OFF? If yes, is it only some of the buttons that won't work or all of them? You said the batteries are good, but are the contacts on the remote where the batteries are seated clean and not showing signs of corrosion?
If it is a touchpad issue, open up the remote and inspect the rubber oad and the circuit board for foreign deposit. If so, use alcohol and clean and dry with a soft cloth or Q tip.
Hope this helps.
