Question about Toshiba 32A43 32" TV

3 Answers


The TV will play perfectly for extended periods, but then shut off with the "on" light blinking. I am on digital cable and had 3 diffrent boxes installed, but the problem continues. I can unplug the TV from the wall socket and after a few minutes or hours, re-plug and start the unit normally. The cycle has been ongoing for several months and the TV is only 2 years old. Store service folk indicate that this is not a good "in-home" repair item and want to carry to their shop to observe for a period of days and then install one or more "cards" to solve issue. Only problem with this is that with pickup and delivery, I am looking at $225.00 minimum, not including the cost of parts. This is scary, since I paid less than $400 for the unit in the first place.

Most Likely it is a bad STR (the Power Regulator IC) in the Power supply circuit.Get it replaced and it should sort out. Should not cost u more than 15-20$ for the STR + Technician fees.

My Sony Trinitron stand by/timer light is on and will let me put tv on but only stays on for a few seconds . Model #KV27S66 Oct 99

Your TV has an overload due to some faulty components inside it. This type of fault is usually noted with overheating of horizontal output transistor connected to LOT of the TV. This may be due to LOT fault, or fault to the transistor itself. When it overheats, it put a short between supply rail, and the power supply regulator system inside your TV will detect that short and will shut down automaticaly. Please note; if the TV works after some time, say after 15 or 20 minutes; and again shuts down after working for a short period, and the cycle repeats, surely there is a winding short inside LOT, which cannot be detected by normal multimeter measurments. If it is so, replace LOT and the horizontal output transistor at the same time.

My screen will turn on right after unit is plugged in and stay on for a short period of time, then it shuts off and the red light near the power button blinks and teh tv will not turn back on. This could...

Unfortunately it has nothing to do with the power plug.

If you turn it on and it works normally but then shuts down it's activating an internal protection circuitry to prevent damage to your set. It's not an adjustment, it's not something you can fix at home. Sorry to be the bearer of bad news but it will likely require a shop repair.

TV goes to green, sound stays on a few seconds then TV shuts off.

Sounds like you have a bad picture tube. More than likely the CRT could be shorted, which would cause the set to shut down.
My first advise would be to power up the set with an isolation transformer with the voltage about 60% approx. 72 Volts AC, and monitor what happens when you increase the voltage slowly.
If the set remains on at 60 -70 %, then when increased to 90 - 100% it shuts down, you have something drawing too much current ( which could be the CRT )

Sony TV shuts off automatically

1.Check first if the shutdown of your tv follows a certain period of time. Example after using it within 12 hours it automatically shut down. If so the the matter is only on settings of your tv.
2.But if your tv shut down at an irregular time the problem is in your board. In this case if your tv still work but still shutting down automatically its better not to use it so that their will be broader damage.
3.The most common defect on this case is loss contact of components due heat and mechanical undergone during the usage of the tv. If you know how to resolder board, try to resolder the components specially those who are showing loss contact. You can recognize it because a good solder one has shinny and no round like on the soldered surface.Try also to resolder important parts such as IC's and transistors. note : a good resolder needs to be done in order to avoid problems and damage.
4.Another possible cause is the tack switch for channels,menu,power and etc. You can remedy it by spraying it a contact cleaner.
5.If the problem still going even after the procedure its better to bring it on reliable and trusted service center.

I have a sony wega

Generally speaking whent he set shuts itself down, the standby light will blink a code. This will be a count followed by a short pause and then the count again etc.

When teh set shuts down, count the blinks and post it here. That will indicate the circuit that has the problem.
