My toshiba 32av500u has no picture completely blak only power little lit in front . turns on green no kind of sound


I have the same problem with the black screen and no sound. Also the green light turns on and off while hitting the power button. Although if i turn it on then off multiple times it eventually turns on and works perfect... Could you do the same thing before it finally quit all together or did yours just happen over night?

42 inch Toshiba Plasma TV has sound but no picture, wife heard a small pop when the picture went off. It is about 4 years old. What could be the problem and is it cost effective to fix or replace it.


That popping sound is usually a capacitor or "cap". Depending on what board it was on, would depend on what needs to be replaced. Usually its the main "power" board. I would say it probably would be worth replacing as these boards are generally not that expensive. If you take the back of the TV off, you can look at the boards. Caps are cylindrical and are various heights and widths. However they should have a flat top and bottom. Look for one that has a round top or bottom. Do NOT touch the boards though. Caps can store energy long after the TV has been unplugged and static electricity can damage sensitive chips.

Tuns on sound but no picture


It looks like your inverter board went bad. what you can do is turn the tv on and make sure you have a chanel set where you can hear voices, now with a flashlight go aroudn the screen to see if you can see a picture. If you can, then the inverter board is not sending power for the backlight lamps

Toshiba 37 lcd tv picture gone sound remains ok looked in back none of the backlighting is lit any ideas.when turned power off heard a pop


The power supply module will be the first place to look, it may have bad DC filter caps, blown or burnt parts, cold solder joints, etc.
Here is the service manual:

My Toshiba 32AV500U - the picture went blank.


This problem usually happens when the lamp runs out, verify how old is your TV, lamps have a life spend of aprox. 3 years, most likely you would have to replace the bulb so your TV can start running again!!

Sounds like it could be a problem with high voltage stages. Definitely a job for a TV technician as it is dangerous try to repair it yourself.
