Re: lines on tv
Set starts, horizontal and vertical deflection work, HT ok, crt heaters ok, but no sound or picture
I turned the G2 voltage up and noticed a white screen with flyback
lines, frame ok. I detected two badly soldered double diode rectifiers
in the secondary part of the power supply ! I checked all other joints,
and everything was ok !! success
White horizontal line (no vertical deflection)
Check / replace R548, R549
Sound but no picture except for a couple of horizontal colour lines
Replaced the frame chip TDA8356, set now ok

Sounds like the CRT tubes are going out which is fairly common on Sony. Inside the back of the TV there are 6 knobs - 2 for each color...one is for focus - dont touch - the other for brightness...turn down the brightness just a hair untill the lines go away.
I have red concave lines going across the screen, plus wording appears double like a ghosting effect, this is ongoing from the time the tv is turned on until it is turned off. This started 3 days ago. Is it time for a new tv, its 9 or 10 yrs old now.
My unit is 9 years old, almost 10 (in 2 months) and started the same a couple of months ago. The only way to fix it is to have them serviced by a tech and replace the projectors. Its just the age/use of the unit catching up with it.
Many resellers sold them with an offer to sell you an optional maintence service where they would fix/clean/replace the projectors for upto 5 years after purchase. I'm not sure if they even have the parts anymore since these tv's are no longer produced. After market repairs are likely to cost as much as or nearly as much as buying a new flat screen tv.
yes there is a small black box with 6 controls on it, take off the bottom front of the tv, behind that you should find a black piece of plastic you can remove by taking out 2 more screws. the black box should be in the upper rhs.now i don't remember if the top 3 are the screen controls or the focus controls. the rows should be labled, you are looking for the screen control row. the green control is the middle one. you can try turning down the control till you no longer see the green lines. try adjusting in a dark room, it will be easier to see the lines & when they are gone. if you problem is not solved by trying this, then i agree with your tech & the green tube is bad. good luck.
they gona get worse to dead circuit, a small capacitor (problably in the neck board) is bothering you, get a tech now that he can see the problem, gonna be cheaper now....good luck
ps some times the picture say to the tech was going on
