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.

Toshiba tv - power on - black screen and power light blinking -

Read below and decide if you want to tackle the problem yourself if so I’ll help along the way with what info I have. If not contact the nearest repair shop armed with the info below.

A dead set (no picture no sound) can indicate any number of problems – Usually the set is in shutdown or protection mode – this means that the internal circuits have detected a problem with a supply voltage missing, drawing too much current, going over voltage or a short condition.
The first thing to do is power off the set unplug it for 5min. than replug and try again. This in effect resets the main micro and will sometime unlatch a fault and resume working. There are certain common problems based on the make model – for instance convergence output IC’s(CRT projection TV’s) can cause a dead set symptom in many models. Vertical output IC failure can also cause the same symptom (CRT standard and Projection).
The only way to determine the real cause is :
By an educated guess based on experience or by directly troubleshooting the set – checking fuses, measuring voltages and checking for shorts. Many of the intermittent problems such as, int.(Intermittent) no sound or picture, int. picture shrunken or misshaped. These problems are generally due to cold (bad) solder joints (all TV’s and electronics) that break down under slight temperature changes or vibration and are usually verified by physically tapping the suspected area on the circuit board, or by quickly heating or cooling a suspected component or area ( cold spray and hot air gun). The other main culprit is leaky or dried out capacitors or capacitors that change value depending on temperature. These can sometimes be seen as bulged or leaky and have an acrid odour.

The TV will not power on at all

Is the set completely dead? if so you should see no indicator lights and hear no "click' when the power button is pressed. If so than the only thing wrong with the set ic the main Fuse (6.3A 250VAC) has blown.

I have a Sony Trinitron KV-1214, manufactured in 1975. When I pull the power-on volume knob, the channel indicator lights up - but there is no picture and no sound. Is it simply dead or possibly...

It sounds pretty dead and the odds of a tv that old being repairable are quite low. To be honest i would say that you're luck for it to have survived that long but it's time to get a new tv. You can get a new tv for the price of a repair anyway.

Toshiba cz32v51power light flashes, with no picture

That means that an internal error had been detected, and now the TV is on protection mode.

To start unplug the power cord for ten minutes, and see if the TV restart.

If it does not try leaving the set unplugged for longer, let say two hours.

If still no luck call the number listed on the user manual, as the TV has an internal fault, and must be repaired by a technician.

Flashing power indicator

Sounds like a power supply problem unless there is a short in the deflection circuits causing the power light to flash. I'm afraid it'll take a technican to figure out what is wrong. If it's more than 7 years old, you might consider replacing it.
