You cannot rejuvinate a Sony CRT without permanate damage. The set monitors the red, green and blue cathodes for current drain. If one cathode is drawing conciderbaly less current then the other two well then a blank picture will result. You notice when you turn the TV on the timer light flashes and when it stops the picture appears? I bet the timer light is flashing alot longer than it used to. This is just a sign of a failing CRT and the TV won't be worth replacing it as Sony CRT's tend to be on the expensive side.

I AM GETTING BRIGHT HORIZONTAL LINE IN CENTER OF THE PICTURE TUBE.& AND ALSO SCREEN WIDTH IS MORE


Sounds as if you have an older model T.V that still use Light tubes to produce the picture,both conditions are indicators that the picture tube is failing. Not many TV repair shops around anymore,since the price of Good quality TV's are realetively inexpensive. may need to buy another.the tubes themselves are very hard to find.

Sound but no picture. I'm thinking I need a new picture tube but how much is it going to cost me?


First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working.
You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.

My rca 52 inch hdtv turns itself off after a few minutes


Sounds like the green tube shorting intermittantly. Have a qualified tech use a tube restorer to check for shorts, or the loss of the 300v line to the green tube.

You have a convergence problem. Go to the convergence menu or consult the owners manual on the convergence procedure and try to correct i if you can.. However if the red image is bowed and or not linear you will probably need to call a technician to repair your set. Most likely the red convergence output chip has failed. This is a common problem with all CRT ( picture tube) rear projectors. Good Luck. Happy Easter

Picture vanished


The problem might have started because of loose conections in the vertical circuit,if the vertical circuit fails completly the screen blanks out to prevent a line being burnt in the picture tube so that part is normal but the problem is still in the vertical circuit.Maybe the IC just went bad all the way and it might have taken a fusible resistor. If you are familiar with tv service you have a place to check but if you are not too familiar be safe and call for assistance from a servicer,is a straight forward problem and it should not be expensive.Let US know how it goes or if you need more information.

Tv has sound but no image


When you say no image this could mean anything from, snow picture, blank screen, blue screen. Also, dry joints on the PCB can cause such a problem. More especially on the picture tube board.
