Question about Toshiba 40H80 40" Rear Projection Television

1 Answer

Toshiba 40H80 --- When the TV is off, there is red light that is turned on which is on top of where green light is. UNderneath where the green light is, there is a red light that keeps flashing even when the TV is off. Then when we turn on the TV - The green light goes on for 2 minutes blinking and then the green light goes out and the bottom red light keeps blinking. If you try again - Same thing happens except the green light blinks for even longer than 2 minutes but never goes steady and turns off. No Sound and no picture ever comes on. Tried pulling the plug and re-plugging in.

    Given prices of 40" LCD or LED TV's these days, would you say it is cost prohibitive to try to repair the set?

The reason why its not powering on is due to a protection fault. That is the reason why the green light comes on, blinks for a while and is turning off. We should perform component level testing on the components, to locate the faulty ones and replace them. This gonna need skills in 1) Using a multimeter 2)Using a soldering gun(to remove the faulty components and replace them with new ones). I do have a service manual for this model and I will guide you to do this yourself if you have worked on electronics circuits before. Note that the set holds residual voltages that can cause permanent disability due to electrocution if not handled carefully. If you want to continue let me know. Otherwise get me your zipcode and I will get you a list of techs in your area.

    Considering the fact that this repair is gonna cost you about 200-300$, it might be a good idea to get a new set. This set is rather old anyway right(10-15 years?).

Toshiba 40h80 red light blinking


I would suspect the problem is in the convergence circuit---only one simple way to know---get at and un-solder all 18 pins on both the STK chips it uses.

Once they are free try to turn set on--if it comes on one of the chips is bad and both will have to be replaced.

Tv has died!!!!


Sarahp_21,
Check the 2amp pico fuse at F470 and if open replace it and Q404 2sc5570 the HOT (horizontal output transistor).. If not open check HOT for short EtoB and inspect the solder connections of Q801 in the SMPS.
If any of that sounds greek you need to take it to a shop or find someone handy with a meter and a soldering gun that can do the work for you.
If I can help any further just let me know.
