    i checked all my soldering they were bridged and i fixed that. I checked my connection they were hooked up right.

    I got the same problem but the blinking light in the front still flashes but it only flashes four times (a second between each flash) and then it stays red. When i push the power button again nothing happens.

Check the pins with a strong magnifying glass to make sure they are solderd correctly with none of the pins bridged with solder, then recheck all the wire connections to make certain they are correctly hooked up.

    If the pins were bridged and you powerd it up you may have opened a couple of the convergence resistors located right next to the ICs these will need to be checked with an ohms meter but 1 side of each resistor will need to be removed from circuit to acurately check them.

Will not come on

It will be the mainboard but not 100% sure because I need a more detailed description of the sympton.

But by the look of your description if it is not fixed with a mainboard it will be the powerboard for sure.

Adjusting the blue convergence on tv

1st. Go back over your soldering and make sure you didn't break a trace and joints are solid.
2nd. Make sure you installed the correct value resistors in there places.
3rd. I believe the blue crt is on your right, follow the convergence leads down to the board to the 4pin plug. Go from pin 1 of the plug to pin 11 on each of the IC's ( 1at a time ) with an ohm meter, when you see 0 or just about 0 that will be the blue IC, I have the PTV 915 manual that i'm using. I suspect you will find a mistake along the way. Take your time and double check everything again and let me know. Good Luck!

Hitachi projection tv

Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence or magic focus section
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
You can get a repair kit that includes all the parts from
They have put together a kit for the Hitachi TV sets.
The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself. Its a fairly easy fix on the Hitachi sets.

Toshiba TN55X81 Wont turn on but I hear clicking

Pull the three connectors to the yokes on the convergence board. If the set powers up, it's a good chance the STK392-110's need to be replaced. I fixed one today, and it has been running for 6 hours now.

I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce

No power,red power lights keeps flashing.

I had the same problem with the 47" version. I called the Sears technician who tried for more than an hour to fix the problem, even calling Panasonic. Final solution: a board repair for $550. Now I have a plasma and a big desk.
