    My Toshiba Proj TV year 2000. Model TZ43V61 has a flashing light. I have already tried leaving the TV unplugged for days anbd it still does the same thing. I have read notes about a mother board problem. If I am looking at my TV from the back where would the mother board be located and what am I looking for as an indication of a problem with it. I feel like I am looking at the inside of a space ship!

Fot flashing light on toshiba tv .--check following.:
From the main power supply,
check diode, capacitor after the chopper secondary windings, the positive of the diode is the B+

if good, check these:

If the supply rail B+ is only about 45V or still lower
solution : replace the horizontal deflection flyback transformer maybe partially shorted

maybe no voltage at all
solution : check horizontal output transistor might be defective, replace if found shorted

maybe there is a good supply say at least 110V , but no oscillator drive on the horizontal output transistor, or blocked oscillator signal drive

thanks.please do accept the solution.keep updated.

Your projection tv has an auto protect mode and it shuts off whenever it detected a hardware problem and thus gives you the led light flashing. It shuts off to protect itself from further damage.

There are several causes like a blown or faulty bulb, the power supply needs replacement or some leaking or bulging capacitors. But be very careful and do not touch these as you might get hurt since those capacitors olds an electrical charge that might cause electric shock that would injure you.

If you are not technically skilled to do electrical stuffs, you should seek assistance to a skilled tv technician.

Should you have any further questions, please dont hesitate to ask.

My blank screen, red flashing light projection tv


Most likely the lamp has failed. The red light will blink with a pattern (number of flashes then a pause) You can refer to the users manual for information as to the nature of the problem by the aforementioned pattern.

Power indicator blinks; but no picture.


Likely to be the STK convergence chips causing a protection circuit to cut in and switch the TV off when turned on. Do you hear clicking when you switch on?

Toshiba TZ43V61 43 in. Rear Projection... Problem


Try unplugging unit for 5 minutes, then plug in and turn on. If this works, your power supply may be going. However it is more likely that the bulb is gone, you can replace it yourself, but make sure you get the right bulb for that unit and take care in the installation of it.Go to the manufacturers website and look up your model and find out how to inspect and remove the bulb.
Bulbs can run for 140 to $300 and can be found on EBAY

Model TZ43v61 Toshiba TV will not power up appears to need reset,power light blinks but no picture. Never had any problem for 7 years.


There are many things that can cause this problem you would need someone who can use a meter and troubleshoot to find the definite cause but the 2 most common are the Convergence circuit and the Z801 module in the power supply. These can both run you $300-$500 if a repair man were to fix it.

Toshiab tz43v61 power light blinking


I had the same thing happen to me 3 times and the first time it was 2 months off of warranty. It is costing me $395.00 each time, the TV is only 7 years old. Lets see I paid $2400.00 for the TV and also have another $1185.00 into it for repairs, and it is doing the same thing again. My suggestion would be NEVER buy another Toshiba product. I find it interesting that their website says "As a proven technology leader, Toshiba is committed to the goal of ensuring that, to every customer, the Toshiba name remains synonymous with lasting quality, durability, and value." WHAT A LOAD OF ****!!!
