I would suspect one of two general things---one if the picture dims out and does not just cut out bad solder connections for the filament in the neck of the tube---a look there with set on will when bad reveal if this is the case.

Bad solder connections somewhere on the main board--this happens with age as the board expands and contracts from heat and then cooling down.

If not a do it yourself person it may not be worth a shop repair on a 8 year old set------

Let me know if need advice.

SOURCE: Sony Trinitron experiences

The screen control inside the set may be on the highvoltage transformer or on the crt socket; either way if you can turn it up just a little clockwise and the picture comes up but doesn't look good you are likely to have a bad tube. Or try tapping lightly on the glass neck and watch the picture as you tap. If it reacts to the tap you have a bad tube. but the turning the screen control is the best test. Turn it the other way the picture goes off immediately. bad tube: too costly if it is available.

SOURCE: tv screen goes black

No, if the picture of your tv screen is clear when when you watching. the troble of your tv is looseboard, and you replace your CRT socket too.

SOURCE: cannot get good tv signal since ITV and other

The transition from analogue TV broadcasting has been painfull in some areas. the only way to get out of this frustration is to buy yourself a digital set top box . This will convert the digital TV signals to analogue form so that your TV can pick them clearly. In any case ,the trend is to have all analogue transmissions phased out altogether

Yes.Take the tv aparts resolder the FBT-the flyback tranformer,that the big black block of plastic with a red wire with a cap hook to a CRT-(tv tube).Also resolders the video board,that the board connect to the CRT-(tv tube) those pins sockets keep the video board and the CRT-(tv tube) together.Tv should be working again,if get these two soldering places parts resolders,FBT-resolders for stable tv high voltage.Video board pins sockets resolders for better joints connections between the video board and the CRT-(tv tube) connections.

17 yr. old 35" RCA loses color intermittently. Picture & sound ok


Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.

Sony kv32s42 trinitron color tv blinking


sounds like a bad picture tube. Picture and bright settings cranked up for a good pic? Test/rejuv with a crt tester and/or look at the Ik signal on the crt board. A good tube has 3 small pulses during blanking. The crt cathodes are checked with these pulses, pulses too low and the jungle IC will blank the drive. If the picture fades in and out I would check the filament ckt but that doesn't support the "blinks"

Constant changes in picture colors.


It is a 20" TV set and will most likly, im afraid to tell you, cost more to fix then it is worth. The problem is a bad Picture tube, an intermittant CRT socket or the video jungle IC is intermittant. If you want to invest in an estimate, check out first if it will go towards the repair, as then maybe you can get it fixed at a good price, as long as the picture tube is not the problem Good Luck
