My crt tv picture is fine. but the sound startes after about 30 seconds

change crt baise socket , it will clear your problem

My Loewe did the same thing tonight. The picture went blank and the rered and green light came on together. Any suggestions?

Yes.... u must adjust the screen voltage going to picture tube....located on the CRT module>>>little board connected directly to picture tube (take back off TV and you will see ) play around with screen control on the CRT module......can be adjusted at times to keep from losing picture!!! tube is bad...i know sure looks good when showing a picture....TRY adjusting screen voltage ( YES while TV is ON>>>CAREFULL ) gl

If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

Sony put i pic killer circut in there tvs. if the tube was not
giving the proper feed voltage on the guns in
the pic tube it blinks off ,sound good no pic.
if you turn up the brightness
on the flyback transfromer you can
get a little more life out of it ,

One of the power supply areas are most likely going intermittent. This can be from cold solder connections on the circuit boards, or from some components failing due to age.

An experienced tech should be able to service your set, but it will be expensive for the time involved. Sometimes these types of faults can be very time consuming to resolve.

it sounds like your "lamp" is going out look for a hidden compartment.. or in your owners manual to see where its located its an easy fix and costs much less than a new tv

Your power supply is going south, I have an old sony with the same problem. The voltage level drops and does not have enough 'kick' to start. It will work better when it is warm. The module will need to be replaced.

Not acutally a solution. We are having this EXACT same problem; it started this week. Let us know what you are having done. I've called Toshiba and service reps but they are all quoting a price which is almost half the value of the tv. Have you been able to fix it? We are pretty upset since the 2year warranty recently expired. Obviously, it seems that others are having this problem as well. Email us: [email protected]

I unplugged it for 24 hours. When I plugged it back in it was ok. It has done it a couple of times since, but only for a few seconds.
