No picture When I turned on the television, it made a popping sound, then just a thin line in the middle of the screen. I could smell burning plastic or something after this happened. Sound is fine. Thanks, Mountain Man

Most likely the vertical oscillator circuit has failed. As CRT televisions have gone the way of the dinosaur, my advice to you is to give a fond adieu and invest in a new TV.

Sounds like the picture tubes are failing,common on sony. do you notice any thin horizontal lines? You mite get lucky and be able to adjust the voltages. Remove back cover and look inside to see which tubes are lighting up.The front panel below the screen will come off and behind it is a small access cover.remove it. there you will find the voltage controls (its a plastic square with 6 knobs). 2 knobs for each tube, 1 is focus the other is the voltage labeled "screen". they are marked so look closely. Green is always in the middle but sometimes they flip the controls for red and blue so pay attention to which you are controlling .slowly adjust screen voltages to see if you can get it to stay on. If you over do it those thin horizontal lines will pop up and the tv will shut off again. If you already have lines back off the voltage by turning knob to the left slowly until they diappear. If that seems to fix it but the problem but it comes back later, then the tubes are shot. good luck!

Hi
This is more than likely your screen controller board that has gone faulty, if the lines cover the screen vertically and are very thin and rainbow kind of coulored then i would say 98% this is the faulty board, Remove the back from your tv and look for a little board (rectangular in shape) that connects to your screen. (Middle top)
Get the part number of the board and Google or Ebay for a replacement.
Hope this helps

I assume this is an LCD tv that you have? I would think a fault has developed on your inverter board with one of the components having burnt out & shutting off the drive to the backlights hence the smell & lines on the picture. It would be advisible to take it to a repair centre to have it repaired to check the burning issue as a matter of safety

It is my guess that you have some intermitent solder connections in the Vertical output circuit.

TV will need service soon, blue CRT is on its way out, will need replacing

Remove the front speaker grill and you will find an access panel (2 screws are hidden behind 2 little plastic caps at very bottom of speaker grill,just pop uot to access screws) .Remove the panel and you will see the picture tubes.In the middle you will see a little black control pack with 6 little knobs.The 2 in the middle are the green controls.They will be labled screen and focus.You will have to look hard for which is which.There may be glue over the controls if so just remove it.Slightly rock the screen control back and forth to adjust retrace lines out.If the unit shuts down during this process back it off a little and turn the set back on and proceed.

This set should be taken back for exchange under warrantee

yes it can still be fixed! the pop sound you've heard maybe came from a blown capacitor in the vertical deflection circuits. this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
