Sony KV-32FX20U picture has a colour cast

Check its video output card [a card directly plugged on to the back of the picture tube] for any loose solder terminals. Re-solder all the suspected solder terminals there, by applying a little more solder to each points. A bad solder point can cause this type of problem.

The picture is really dark even though I have the brightness set to a hundred percent

brightness isn't brightness, its technically called white level, as for the fault, probably a power supply issue, also turn the brightness down as having it set to high can cause long term damage to the tube.

Oversized picture problem

Several possibilities, if you use a set top box to get your signal like a cable box or satellite receiver they will have settings that effect picture size. It could be a high voltage problem inside the TV causing an effect called blooming, if that is it you can usually change brightness and or contrast and see the picture get smaller and larger. I don't recall that set having any customer settings that could give that symptom.

Hitachi Standard T.V.

Some of the problem could be a weak or damaged picture tube - especially if it encountered rough handling in the move. Other possibilities are bad capacitors in the power supply and deflection circuits which are common with this aged set. No adjustments come to mind that could permanently fix these symptoms.

Tv has bright green color

you are having a problem in your video circuit and your tunner section if the green is smooth also have the deflection ic checked.but this set needs to be taken to a qualified tech repairs could cost about $1oo.00 good luck.

JVC 27" AV27F803 Brightness fades to dark intermittently

I likely you have a loose conection in the crt board at the neck of the picture tube or a loose conection close to the high voltage transformer,I would suggest to tap the main board as well as the crt board with a wooden or rubber handle(not metal),be attentive were you tap to see if the set reacts ,if the set reacts you will need to resolder those places ,be carefull working on a set that is on while you do it,this should give some idea what the problem could be in case you want to call someone to help you with the repair.Let Us know if you need more information.

Television fault

On this set its a common thing to have an intermittant connection on the crt driver board. That would be on the socket itself or on the driver transistor. Also could be a driver problem as one of the drives comming from the video jungle IC could be bad or even in some cases could be the picture tube. Hope this helps.
