Check the heater power supply. you can find it at the CRT circuit at the back of the Picture tube. labeled H1 and H2 check the resistor Bias or re-heat CRT socket.

    tv life is only around
    7 years. there is several different circuits in the tv that can cause
    this problem. a repair cost will range 800.00-1500.00 depending on what
    boards are bad. it could run more but the set needs to be looked at to
    be sure.make sure when you call a repairman he knows what he is doing..........

    good luck..............

    That also means that either the X-sus, Y-sus or the Z-sus board isn't
    powering up the pixels....I doubt the power supply is faulty since you
    do get sound.

    I suggest that you check the cords again and see if they are loose
    Also check the display settings and television settings by using your
    remote. If these do not work, try getting your television checked by a
    repairman as maybe he could fix your television set.

No Picture on Magnavox 42" Plasma TV


Plasma displays use a fairly high voltage and the supply for it has failed.
If you want to check on your own, remove the back panel and look for one or two boards with far fewer and larger than average components on it or them.
If two boards are present, the one most obviously related to the incoming AC cord will be the main supply but in some sets, the main and HV supplies may share a board.
Locate the part # and email the manufacturer for a price on repair or replacement.

Check your cables and TV input settings.  Can you get to the on screen menu?  Does anything appear on the screen when the tv is on?

RCA 42" plasma: The screen suddenly displayed distorted random colours & stuck on that, Sound works but the screen is stuck.. it does not work anymore. Is this a common problem in RCA Plasmas?


yes this is commonly happening to these plasma tv's, it is the video processing board
and it will need to be taken to a repair shop , because only certified service centers can get these parts from the manufacturer , there is a replacement kit that is available for these problems , do you still have a warranty?

Plasma TV buzzing


If the adjustments on the power board are correct and if you are not at high altitude, the plasma display panel is defective. If the set is off warranty, it is not cost effective to replace the display panel. If it is off warranty, you should give the manufacturers Customer Relations a call. The phone number is usually right on the back of the tv. The manufacturer of the tv might make a warranty concession if they are concerned about their brand reputation. Some manufacturers find it less expensive to just switch brand names rather than make good on defective products. If all else fails, you might get some money back by selling the circuit boards on eBay.
