Question about Toshiba CZ36V51 36" TV

1 Answer

Power light blinks and no picture

Occasionally when turning on my TV the red power light will blink and there will be sound but no picture. Then it will stop blinking and the picture will be perfect. It happens more often when you turn the tv on more then once a day or if I used the remote to shut it off.

Re: power light blinks and no picture

No picture - screen is empty. Sound is ok
Check IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this IC
No picture and sound, only a high pitch sound at switch on
Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 200ohms
Picture fades away few seconds after start-up till no picture. Sometimes no picture at all. Sometimes picture OK for longer. Sound unaffected.
Faulty joints on CRT pcb. Cracked solder joints at tube socket connections on CRT circuit board. Caused variable supply to CRT heaters. Resolder all socket pins to pcb.

Sounds like you have an internal fault (probably on the power supply board) This is the board that generates the various voltages for the various parts of the tv circuitry. The best is to take it to reputable tv repairer(just what you didnt want to hear hey)

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.

Power surge-no picture or sound, just red blinking power light

Any malfunction associated with a blinking redlight usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.
