My Sony CRT TV produce red picture that shakes, I have tried to adjust on FBT without success, please help me

Buy a new TV, no one repairs bubble tube sets anymore

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.

open the back cover of your TV (unplug the unit) using a soldering Iron,resolder all the components at the CRT socket .the small square board attached to the tail of picture tube That's it! good luck and please dont forget to rate I need it to keep going...

The set has a high voltage problem, "the flyack transformer is defective" It generates the high voltage in the picture tube and with the help of the video circuits it produces a picture. It is not cost effective to repair the tv, cheaper to replace.

Lines means Screen Drive is overdriving, try adjusting the Screen control on the FBT flyback Transfomer, adjust it down. If that does not Clear out Problem then replace the CRT Board that is connected to Picture Tube.

U have a soldering iron,desoldering pump or a roll of desoldering braids,a roll of solders?Can u do basic soldering and uderstand basic electronic?FBT- the flyback transformer,the big black block of a plastic with a red wire with a cap hook to a CRT-tv picture tube.Near the big block of a plastic with a red wire with a cap hook to a CRT picture tube.Inside to the right of the FBT,there are 2 power supply ICS,those 2 ICS are dead.Replaced these 2 power supply ICS near the FBT,will solved this tv LED power light indication blinking and will have stable tv power again,and tv will work.

Take the tv aparts.Caution high voltage ERA FBT.The FBT the flyback transformer.That the big block of plastic,with a red wire with a cap hook to the CRT(Tv tube).On FBT that big block of plastic there are 2 knobs one said FOCUS the other said SCREEN.Turn knob said sceen down a bit,will stop get very bright pictures and shutdown,the screen will hold high voltages.

HIGH VOLTAGE WARNING - open the tv and on the flyback Xformer, there should be a knob that is labeled FOCUS try adjusting it. the flyback has the red wire on top that goes directly to the the top of the picture tube.
