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.

My 21" Plano TV , replace the Picture Tube becous


It sounds to me like it has the wrong scan coils fitted to the replacement tube and there is no fix for that. You will need to fit the correct tube or have the old tube re built.

My tv picture turns all blue in about 2 minutes after the television comes on.


Hi,
I'm afraid, it is problem of blue picture tube in your tv that will be replaced to solve this problem.
Since tv is an old model so it is quite possible that blue picture tube would not be available any more, call local tv repair shop for blue picture tube replacement, if available somewhere, as it is not user level fix and experienced tech can do it.
Thanks.

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

Where can i find a replacement picture tube for my akai 42" LCD tv?


Due to residual electricity, replacing a TV's picture tube is very dangerous. I would NOT do it myself. Besides this, getting a new picture tube frequently costs almost as much as a new TV would.

You can contact a local repairman (if it's still under warranty just send it back), and get an estimate, but seriously consider getting a new TV.

Sony Trinitron Picture Tube replacement


I think that you will find the picture tube to be more expensive than a replacement TV, if it is still available (unlikely). That being said, it is also unlikely that the tube itself is the problem, The more common problem is the horizontal output transistor or the flyback transformer. Either part should still be available for a reasonable cost. Check with a local servicer for the part numbers and costs. These are common parts.
