Your fluorescent tube or the board driving it is bad. Have the tube checked out before you spend a lot of money on a circuit board, this is not something you should do yourself especially if you are not a TV service technician.

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.

Failing power supply

Here's the test to determine which board is faulty. With the TV on, as usual, shine a flashlight on the screen to see if there is a faint picture. If there is, then the ballast board for the backlights is bad. If there is no visible picture, then the T-Con board is bad.

Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" 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 1000 posts to different brand TVs now. Pull up older posts there. Faults to Plasma TVs are described in detail there. Check it. Just see, almost all Plasmas are built on same type chassis and board configuration, so the fault to these sets too will be almost the same in nature.

R U referring to your furnace, if so, does your furnace have a name? There should be a listing on your unit to explain the codes.

No screen boards found. Do you mean any of these?
Types of TV Boards Every TV uses a collection of various boards to perform every function imaginable in a television. The boards work together to produce sound and images on a television screen. When certain mechanisms in a TV fail, it might be time to start testing different boards to see if they are functioning properly.

Main Board

The main board is the central hub of a television circuit system. The easiest way to identify a main board is to find the board with the various video and audio inputs/outputs. Generally speaking, main boards also contain a tuner, HDMI, USB, and S-video port. Main boards are one of the largest boards in a television. Main boards might also be referred to as a motherboard, main module, or an A/V board.

Power Supply Board

Another large and important board inside a television is the power supply board.. Usually found in the center of the TV, the power supply board has several connectors that supply power to the other circuit boards. It can contain transformers, large capacitors, and integrated circuits. There is usually a table on the power supply board indicating the different voltages it produces in addition to the signal names.

Inverter Board

Found on LCD TVs, inverter boards are used to mount the LCD backlight. These are smaller boards, usually shaped like long thin rods. If an LCD TV's screen is dark, distorted, or difficult to see, it can be the result of a defective inverter board. Inverter boards fail when inadequate power is not allowing current to pass through the backlight bulb.

Timing Control Board / Logic Board

The timing control board, known as the T - CON board,, is typically only found on LCD and LED TVs. Plasma TVS, on the other hand, use a logic board.. The functions of the logic and T-CON board are similar, as each functions to digitize the information it receives from the TV's processor. This allows the screen to display images on the pixel level. When the T-CON or logic board fails, the screen images may become distorted, leading to pixelation and the appearance of lines on a television. On a logic board, there are slotted connectors on all four sides, while T-CON boards have connectors on just two sides.

X-Sustain and Y-Sustain Boards

Also known as the X-SUS and the Y-SUS, the x-sustain and y-sustain boards only appear in plasma screen TVs. The x - sustain board might also be called the Z-SUS. These boards function similarly, producing proper screen images. Although they serve pretty much the same function, the two boards work independently of each other. The x-sustain board activates all the display lines at once, while the y - sustain boardaddresses all the individual lines of display. When one board breaks down, it probably will not affect the functionality of the other. However, it might be a good idea to have both replaced because X-SUS and Y-SUS boards have a relatively short life span anyway. A failure of one could mean an impending failure of the other.

Buffer Boards

B uffer boards are also only found in plasma screen TVs. Connected to the y-sustain board, a buffer board works to turn output to the plasma display. Common defects of buffer boards include the burning and shorting of power lines.

If you have a flashing red light, try this first: The flashing red light is, according to the Hitachi service manual, an indication of exactly one problem. It is that the fan (internal, blows air over the power supply heat sinks) has failed. In my case, it failed by continuing to spin (very confusing), but put out a signal (3V on the white wire of the fan harness) that it has failed (I had to look up the data sheet on the fan to figure this out). A new fan from Arrow $10 fixed the problem. If you suspect your fan, spinning or not, you can safely short the white to the black wire to see if your TV remains on after being turned on (solid red light), and then try turning your TV on (blue light) to see if it works.

That POP that you heard is most likely the end of the line for that plasma TV. From your description it sounds like the Z/Xsustain board has failed in your tv . The cheapest way to repair this of course is to buy that board and replace it yourself.
This is not as difficult as it may sound if you are handy with a screwdriver and used to repair things like your own pc or your car etc.

Second cheapest option would be to buy that board yourself to avoid markup prices and have a pro replace it for you.

Check the manual. I doubt that the rca audio is for output. More than likely it's the audio input when using composite video.
