Most likely, the power supply, and or one of the scan circuits are in failure.

You would have to have an experienced TV tech do some diagnostics to determine where the area of failure is.

TV loses its picture after 1-2 seconds after switching on, but sound continues normally. Why is this?

have someone take a look at the power board in the set for any sign of puffed up filter caps--ones in example below are extreme--tops must be perfectly flat with no signs of brown material leaking at top of bottom.

Common failure in sets around 2 years or more of age and some it happens much sooner.

My Sony Trinitron TV 1999 (KV-32V42) made a strange popping sound and I lost both the sound & picture. When I turn it back on, the two red lights on the front of the TV(standby/Timer light & Stereo...


The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.

Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

If the issue continues to occur, service may be required.

Thanks for using Fixya.

Although you did not mention what the make, model number or type of TV it is, I will assume that you are using a cable or satellite box, and the most common reason for what you are seeing is the TV is on the wrong channel. Using the TV's remote, make sure the TV is on channel 3. Most of the time that is all you need to do.
