your problem could be anything from a blown fuse to a faulty regulator transistor. I would check the fuses first followed by the regulator transistors. Let me know if you need any additional info.

the deflection/convergence board requires replacing.the set is checking itself and found a problem and went into shut down.

IF THE CONVERGENCE IS NOT ADJUSTING COMPLETELY THEN IT PROBABLY NEEDS NEW CONVERGENCE IC's . ALSO CHECK OUT THE SHARPNESS OF EACH PICTURE TUB (CRT) THESE SET ARE NOTORIOUS FOR HAVING BAD CRT''s (WHICH ARE NO LONGER AVAILABLE).

Check the following :

1. when you switch on the TV will you get any burnt smell near TV,will it try to on or will it make any hissing sound .

if there is any hissing sound there may be some short circuit happening inside ..
if it doesnt tries to on then the powr supply might not be coming to the screen or the CRT might have got damaged ..,, if this is the case then CRT must be replaced ...

if the power is not coming to the screen then there may be some problem in the transformer or due to some short circuiting some of the component might have burnt you need to identify that and replace that ... this solves your problem ..

thank you
regards

use manual convergence to re align the colors. the owners manual tells you how to do this. No manual go to samsung. com in the FAQ section

Your power button may be stuck? Depress it with the TV unplugged. Make sure that the button is moving in and out properly. If this does not fix the problem, it probably needs service by an authorized service center.

You need to check for bad soldering in your tv .

Also bad capacitor can cause this problem ,

How old is your tv ?

Samsung HCL4715W... | Answered on Oct 18, 2008


Have you tried unplugging the convergence yokes and then try powering up the set? Its not uncommon for that chassis to shut the set down when the ICs are bad.

That model is quite famous for the deflection board going bad . They arent that exspensive to replace. If you need more info just respond to this same post.

Samsung HCL4715W... | Answered on Sep 07, 2008


In these projection sets, usually the convergence board has failures. These can be some of the IC's and or a number of the capacitors in most cases.

You will have to call the authorized service rep, or a service center that is familiar with your set and has availability of parts for it.

Considering the age of your set, the risk of investing in to an oder set, it may be a better option to consider a new one at this point.
