In fact, the TV is in dead condition now. It will be best to contact any service technician. Troubleshooting should start from the main power supply regulator board itself.

You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

This is a display device or monitor only. It lacks a tuner, so there is no way to connect an antenna and tune off air TV channels - and as such; fails the definition of a TV. A TV by very definition is a monitor AND a tuner. Without the optional "RTB421 RCA Terminal Board" installed in the monitor, it can only accept a PC Input signal (VGA).

If the RTB421 is installed, you will be able to choose from PC, Video, S-Video and RGB signals. The full details on this RTB421 Terminal Board and how to connect source video devices for playback is explained on pages 32 through 35 of the manual.

If the RTB421 is installed, and connected to a source video device (Cable TV converter, Satellite Tuner, Blu Ray player, DVD, VCR, etc.) as shown in the manual, you should be able to scroll through the inputs by pressing the Input button on the monitor or remote (make sure the batteries are fresh). Keep the lower left bezel of the monitor clear of obstructions that can block the infrared (IR) remote receiver window.

I hope this helps and good luck! Please rate my reply - thank you.

if the screen is physicly broke not worth repair. if you just cant get video it could be y-sus board or z-sus there are just a lot of things it could be kinda hard to give you a price a repairman might charge sorry

It may well be repairable since it probably isn't that old but with the plunge of flat panel prices, it may cost more to repair than replace. 
If you replace the whole set, don't buy another plasma; while they are a tad better than the LCDs of the period it was manufactured, there isn't much difference in the two systems today and the LCD display will not decay over time as the plasma is known to do.   

Power board require changing.It dead.

My experience with 42" plasma tv's with no picture or sound was a missing power supply voltage. On the power supply board check voltages on the plug. The voltages should be marked on the board,

It's not difficult, but it's dangerous. Your best bet is to look for a repair person right here on Fixya - just click on the link that says My Products above, and it's cake from there. 
It's a quick process, and it shouldn't run you too much more than  the 252 you already spent... and you're saving yourself the risk of electrocution. Those parts are crammed in there like a game of Tetris.
Good luck!

This is a known issue with this TV. The following might resolve it: Check Mute and Volume: Ensure that the TV is not muted and that the volume is set appropriately. Sometimes accidental button presses can lead to muted sound or low volume. Inspect External Speakers: If you're using external speakers, verify their connections. Loose cables or faulty speakers can cause sound issues. Test Different Inputs: Connect a non-HDMI device (such as a DVD player) to the TV. Observe if the sound distortion occurs. If it doesn't, the problem might be related to the HDMI signal from your Virgin box. HDMI Troubleshooting: If the issue persists with the DVD player over HDMI, consider the following: HDMI Cable: Check the HDMI cable for damage or loose connections. Virgin Signal: Contact Virgin to inspect the signal/lines and replace the box if necessary. Mainboard Replacement (if needed): If the sound distortion persists, it could be due to a faulty sound processor chip on the TV's mainboard. In this case, consider replacing the mainboard.

1. Locate the Battery Cover: Look for the battery cover on the back of the remote control. It is usually a small compartment that can be easily opened.
2. Remove the Battery Cover: Depending on the design, there may be a latch, screw, or sliding mechanism to secure the battery cover. Use your fingers or a small screwdriver to open the compartment.
3. Remove Old Batteries: Take out the old batteries from the battery compartment. Pay attention to the orientation of the batteries, so you know how to insert the new ones correctly.
4. Check Battery Polarity: Take note of the positive (+) and negative (-) signs inside the battery compartment. Make sure to insert the new batteries with the correct polarity to match these markings.
5. Insert New Batteries: Place the new batteries into the battery compartment, ensuring they are properly aligned with the correct polarity. Press them down gently to make sure they are secure.
6. Replace Battery Cover: After inserting the new batteries, close the battery compartment cover securely. If it has a latch or screw, make sure it is fastened properly.
7. Test the Remote: Point the remote at the device it controls (such as a Toshiba TV) and test whether it responds to your commands. If the remote is working correctly, you have successfully replaced the batteries.
8. Dispose of Old Batteries: If the old batteries are no longer usable, make sure to dispose of them properly. Many communities have designated recycling locations for batteries.
