I have owned an emerson tv for two years now. All of a sudden the picture has become very blurry and white. It is not the cable connection and a DVD is also white and blurry. Even the input channels are...

you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again

Toshiba 32D46 - White Lines at Top Of Display and TV Not Turning

as i've read you statement your tv need to check parts by parts, the one you mention upside trace vertical line, that part control on vertical ckt faulty parts nearly to faded filter capacitor you can directly replace all capacitor of vertical section. the one you adjust is that the playback transformer the upper portion is focus and the lower portion is screen voltage controlling screen voltage supply to crt g2 pin. if you turn this high that resulting hazing sound come from 2nd anode cup.

This is usually caused by bad capacitors in the vertical circuit. If you have an electronics background you should be able to find the defective ones with an ESR tester .

JVC AV-32F704 32" TV Picture is blurry - cannot read any writing on the screen

You didn't mention if you saw fine white diagonal lines running through the screen from top to bottom. If so, you likely have a shorted Picture Tube which is not usually fixable. If there are no lines seen running through the screen, then it is possible the High voltage transformer which also has a screen voltage and focus control built in that could be bad. I would expect the cost of that part to be about $100, so the repair cost total could approach that of a new set I would guess.

Toshiba 36zp38b picture problems

With it only being about 3 years old, I would suspect bad solder connections rather than defective components like Capacitors. You may get the symptoms to come and go by slapping the side of the set or jaring it slightly which would prove the bad connection thesis. It is not a permanent cure however and you can make it worse if you keep doing that. A solder repair shouldn't run over $225 in my opinion.

TV has cloudy, blurry haze

The two symptoms are related and are associated with the high voltage transformer,since the problem developed overnight is going to the help of a qualified technician to diagnose the cause,if you are familiar with tv service look at the horizontal output transformer for signs of damage but be careful,there are dangerous voltages present.Or be safe and call for help.

Blurry tv

Sounds like theres a leaky capacitor in the screen drive circuit. I have seen this problem also be a gassy crt but was able to clean off the grids of the CRT with a crt/rejuvinator. It happens because of low emmissions in the tube and when white is on thats a mix of all the colors, so the tube works harder. I bet when you whatch a movie and the scene changes suddenly to a white or brite scene the pic looks a little washed out. If this is not the case then I aggree with the Pravin and try it on another TV just to be sure .. This is not a repair for a consumer to do, though however it is only a three year old set you stated, so there should be life left in the tube, so im kinda thinking a capacitor is bad. Seek out a yechnician to check this out for you as a TV is not a place to see it you can fix it or to exoeeriment with. Good Luck
