That is the deflection board which is no longer available. I have a source that rebuilds circuit boards but that item would be around 350.00 to rebuild the entire deflection board. Heres the link if youd like to contact them.

My Toshiba 65H81 65" rear projection TV's picture


You do not have individual lamps in that model. You have 3 individual picture tubes of which I don't believe they are bad. They have fluid in a reservoir that becomes cloudy after time and needs to be replaced, however this is something you cannot do yourself. I recommend you call a qualified technician to take care of it for you.

Tv will not turn on....power button only flashes...what's wrong????


There are a number of fuses on the main board about 10. One is and glass fuse were the power cord is, that one is ok because of flashing. the other ones are solder-in and you will need a meter to check them, they start with an F---- and some numbers and are marker on the board. Good Luck

Somewhere along the line you may have missed a cable connection. Recheck to be sure that all of the wires are reconnected. Also, check the +5V line. In the area of the convergence Ics there should be a number of pico fuses. One of those may have opened up.
Keep us posted.

Toshiba 65H81 blinking power light


Hello

I have the same thing going on with mine. What it is the SLR main Reg. is bad. The only way you can fix it is you can't put just one part in it you have to replace one of the boards. When you open the back panel up you will see three boards in a roll the one that needs replacing is the power board you have to get the model number. My Tv is a 65 HD model 65h81 the board on mine has a part number of PD 7400 yours will have something like that. Well let me know how it's goes my E-Mail is kenjr1@iwon.com

Toshiba 65H81 blank screen and red blinking light....help


I don't think is any lamps.
If you are handy try to open the back of your tv, (unplug it first) don't touch anything just yet, you need to make sure you discharge any static left on the power board (the first from your left )Unplug power cord from the board. Take a heavy long screwdriver (Isolated) and lightly, touch a few parts on the board including the thick red wires that go to the lamps. Once that's done its time to put your dexterity at work. You need to lift that board (PD 0074) so that you can check some fuses like F850, F852, etc. for continuity. Mine were out. I had replaced those two and I had tv for another year. Remove the screws that hold the board. Now, this board PD0074 is connected to the next board by two white connectors and one blue. ....lift them up from one side with your finger nail. Don't unplug anything from the power board, just loose some wires so that you can lift the whole board on one edge. Get a voltmeter and set it to check continuity. Mine has a buzz. Look for them fuses if they are bad , ....replace them. (You can buy them at Partstore.com.....punch in "fuses"or "125V 2A")
In my case that was the only problem a year ago. Now I also have the same problem but this trick didn't work for me anymore. The Power Co,. messed me up big this time. In fact the problem with these Toshiba rear proj. is that when the power in your house goes out and comes back right a way in a split second and you don't have a power regulator, guess what : 'red led blinking'
In my case this time the whole power went on and off a few times within 10 sec. and by the time I got to the TV to unplug, it was to late. I think I have to replace the whole PD0074 board....and that's expensive.
Good luck

No need to take the front screen out. The power deflection board is messing up with that red light.
