I have audio but no picture on my Zenith Z50PG10 50" plasma tv?


Plasmas are like tube TV's(CRT). Once the plasma tube breaks, air gets in, plasma gas gets out. And that's it. They are an enclosed vacuum picture tube. I don't know why people buy plasma. The newer LED have a much better picture. Rich people who swear by plasma, are ridiculous in my opinion. Again, if plasma tube breaks, thats it. Any wrong jarring can break a plasma tube.

How long u have this RCA analoge tv?Around 10 years or more and used it like about 5 or 6 hrs everydays?Yes,than ur tv it is losing CRT tube radiation cohetion.As times go bye years in years out the tv CRT-(tv tube) radiation will slowly dying out,Tv actual pictures will lost some of it luster and it brightnesses to the tv auctual pictures.Brightnesses of CRT tube will get darker and darker until the tv actual pictures barely it is watchable anymore.Contrast,Brightness and Colors adjusting more will help some.But u have to take this tv aparts and take a Flat scerw driver turn up a little bit more of the tv HV-(high voltage) SCREEN button on the FBT-(flyback transformer) to make any big differences of the CRT tube brightnesses.The FBT-(flyback tranformer) is the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).This adjustment on of the FBT,HV-SCREEN button will help the tv CRT-(tv tube) last another year or two.

I have no picture on my JVC AV-27730 tv. Where is the picture tube and can i replace it myself?


Hello
Picture tubes are available at electronic spare part shops. You have to give them the number and type of the picture tube, to which your JVC TV has. Picture tube, along with its Yoke fittings are integrated, and you can replace it by yoursef at home. Be very carfull in handling the picture tube, as they are highly vacumed, and will explde by hard hits. There will be four seating screws on the four corners of the picture tube, and these slots will clearly alaign if the picture tube selected is orginal number. Diamentions of these holes will be different to spherical and flat picture tubes. So you must first aware of the type of picture tube, which the TV has fitted earlier. OK.

Turn tv on the the morning has sound but no pic until tv warms up (about 15-30 mins)


Hello
Your TV has CRT socket problem. This is due to the improper contact of that socket to TVs picture tube. All TVs picture tube [otherwise says as CRT means Cathode Ray Tube] is connected with the remaining control circuit wia a picture tube base card, which can be located at the extreme back side of the picture tube. It is plughed in to it via a socket, and that socket is directly soldered to the base card. The socket mentioned above is faulty. This fault will be more at rainy and winter seasons. During these seasons, your tv will take more and more time to display picture. Because, during this seasons, humidity in the atmosphere is high.
Here replacing that CRT Socket is the only remdey. For that you have to open the back cover of your tv. Locate the base card, can be seen at the back of the picture tube neck plugged in. Unplug it with care, not to damage the picture tube neck or its pins. Do not apply high pressur or sudden jerks. It may break the neck of the picture tube as it is very tender with respect to the other parts of the picture tube.
Desolder the socket from the base board, it may have 9 to 12 connections to be desoldered. Take it out, and go for the same type number and pin confugaration. Replace it with the new one.

NB: Keep children away from you when you do this work. Be sure to unplug the TVs power chord from the wall socket before attempting to open it. Keep out all the connections to the tv, and make it idle. Ok

Horiznal line across screen


The picture tube itself is not longer being manufactured and the replacement might exceed the price of a new TV.
The vertical line you see on the picture tube is not a failure with the picture tube but a different part inside the circuitry.

RCA Model # 20F510TD TV/DVD


What makes you think the picture tube is bad? What exactly are the symptoms you see? The RCA 20 inch picture tube is a good quality long lasting tube and I doubt I have ever seen a bad one.
