Question about Toshiba 65H80 65" Rear Projection Television

1 Answer

My 65H80 is dead

I have a 65h80. It has worked great for 9 years. Last week while watching, it just turned off. We unplugged it and plugged it back in and it worked. This happened a few times. Then last night, it happened again and now it just won't go back on. when we plug it in and turn it on, it makes a clicking sound, but nothing else happens.

Kind of sounds like open conections on a regulator ( bad solder) give it soft shake
and see if that causes it to work or not work.

Disassemble Toshiba 65H80 tv

No, cabinet is glued and screwed---entire front screen can be removed and the mirror inside also(be very careful with that) as they are the two things that get damaged most when transporting a set.

Moving a long ways or just across town?

Our school has a 65h84 65in.; someone moved the t.v. without unplugging it. The prongs from the cord are now in the electrical outlet. We have no way of plugging in the t.v. 1. Can we get a replacement...

1. You can get a replacement "male" end of the cord for a couple bucks at Home Depot/lowes/tru-value etc.etc. It just snaps right on the end of the cord.

2. The plug can be detatched from the wall?

My Toshiba 65H80 has red convergence problem. It

You may have cooked your new IC's
I am working on the exact same problem with the same symptoms. Make sure the tv is unplugged for at least 5 minutes before poking around. The power cord can be unplugged from the power board and removed to keep anyone from plugging it in while you are working on it.
Check the output resistors that are beneath the heat sink on the left side of the board. There are also fusible resistors, like #7711, on that side.
Check fuse 853 on the Power board. This is the board on the left when viewed from the back of the TV. You can remove both boards in the carrier by carefully unplugging all connectors, noting their locations and routing.
To remove the high voltage wires from the splitter, mark them for position then grasp the boot and turn counter-clockwise about 10 degrees to unlock them and then pull up while holding the High voltage splitter. The small high voltage wire can be removed from the flyback transformer by pulling hard while holding the flyback.
STK392-110 can be replaced with STK392-120, STK392-180, STK394-160.
I have found most of the parts at Also check out this site for some very good info:
btw: I am not affiliated in any way.
Make sure that while you have the boards out you look for any bad solder connections. A lot of problems arise or return because of this.
I hope this helps, I have been doing a lot of searching to get this info and hope it helps you.

Too many people want to trickle the info and pretend they are giving you gold. A few hobbyists or people that can't afford to pay $300+ for repairs are not going to hurt their business.
Be safe and share knowlege freely!

ONLY HD2 works, which is used most of the time.

I would look to see if a set up menu on the set has the other inputs lock out.

Toshiba 65H80 has yellow hue.

Check you HD inputs or source. Sounds like the red stream is missing; maybe a loose cable.

Yes look for and check your set and make sure it's the stk392-110. If you can solder you can carefully change it. I would replace all, you may have 2 or 3 in there. Also make sure you don't bridge the pins. Meaning soldering 2 pins together, just be careful. Unplug set and be careful of unscrewing board.
