Question about Projection Televisions

1 Answer

Samsung HCN473WX/xaa This problem on model HCN473WX was fixed by a Samsung authorized repair center july 06((both IC's STK302040 on convergence ) - 1 month later the same thing happened - this time they took the set and held it for about 2 weeks - returned it and it ran fine for about 4 months- now the same problem is back. (out of warrantee). I have some experience in electronics, and took a look at the CG board and noticed a cluster of resistors that appeared to be burnt (RZ123,124125,126). Rechecked solder joints for IC's replaced and they look ok. Does anyone have the specks for this cluster of resistors.

Re: samsung HCN473WX/xaa

The tv shuts on and off by itself and the timer light flashes while doing so. I unpluged it for a couple of days and plugged it back in. The tv worked for about 5 hours and then it started shutting on and off again by itself.

Help not sure

This maybe the problem why it is repeating. They didn't change all return resistors. they are different sizes all are probably smaller than 100 ohms. You will need the exact size and there are caps that maybe bad and maybe fuses also

Another Question Please.

Horizontal lines can be cause by many things. One of which is the convergence module. $130.00 is a little high for something that can be caused by other things as well.

My sanding tv hlt4675sx xaa keeps turning off. When I turn it back on here a little grinding noise... now when I turn it on can here the fans come on nothing else. No light from the bulb is showing from...

It sounds like the color wheel has fallen apart. I would recommend calling Samsung at 1-800-samsung to find the closest service center. This can be a difficult repair and I would strongly recommend a Samsung authorized repair center.

Replacement color wheel for samsung 50'

I am having the exact same issue with the exact same TV. They no longer make that color wheel, so I am looking for a replacement part as well.

I am looking at the 01103A as well from here:

I think I might just order it, and if it doesn't work just return it.

Dead Samsung

I don't recommend working on the TV unless you have some experience and knowledge relating to the safety issues and electronic repair. Most rookies will not successfully complete the repair and probably do more harm than good.

Sometimes when the convergence chips fail, the TV senses the changed load condition and shuts down.

Unplugging the blue, red or green convergence connector on the convergence board removes the overload condition if the IC is shorted and allows the tv to run, with one color missing.

This is done with the tv unplugged. Then plugged in and turned on to see if it starts. Turn off immediately if you here it start.

Now you know if convergence failure caused the shutdown. You can repair the convergence circuit if that is the problem.

If this has no affect, then you could have a number of different faults in Vertical output, Power Supply or HV circuits that require the expertise of a qualified service person. This would be a bench repair in most shops.

If you live around Calgary, Alberta try me instead:

Or try to the find the repairperson part of this website (on the Homepage) and search postal code. Maybe you will be lucky and someone from your area is listed for Projection TV repair.

Most rookies doing this job will cause damage and not be successful. They will pay double for someone to fix their mess or end up scrapping the TV. It is not a simple task. It is more difficult than batteries on a remote.

Good Luck

Samsung HCN473WX

you may need to do convergence to align the colors up.
the only thing other than the ic that need to be replaced are resisters and if the resisters are bad you would not be able to move one of the colors, and blow out the ic you just installed.
