I have a Samsung Tantus HCL473W, when adjusting the convergence the screen bowed and it smoked. Is it possible the power supply went out, or worse?


Itispossible that the high voltage module went out, and to have it repair you are looking at babout 500, at the lest, and if it was me I just buy a new LCD, prices have really went down.You can good to www.partstore.com and checkand see if they have a highvoltage, deflection module, for your set, Take care.

If the lines are slightly curved and stationary on about 2/3 of the screen its either the Blue CRT or the Blue CRT drive board which is having the problem.

Convergence circuit correction


BEWARE some people suggest that the IC's can be replaced and that they are part of the convergence circuit, they are on the POWER board for the convergence circuit, the convergence is a separate 'card' that is almost the same price as the 'sub board' with the IC's. Although most people favor the sub board as the culprit.

My Philips HDTV 60PP9202 has blue and red curved lines



Check to see if you can adjust the convergence. If you can't adjust the red and blue in all directions you need to replace the convergence chips and resistors. If you not sure how to check the convergence goto the site www.TvRepairKits.com and goto the Tips section.

I need to really find an HCL473W tube, can you help me??


Hi,

Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.

This requires the replacement of the defective IC or ICs and any damaged or smoked resistors. Usually there is little alignment required after the repair. If you play with all the adjustments before the fix, hours may be spent re-aligning.

Don't monkey with it.

This is a delicate and difficult repair. If not done by someone with some electronic repair experience, the TV will likely end up as junk or cost considerably more for a tech to fix the damage done.

If you live in Calgary, call me. If elsewhere, find a competent tech.

It sounds like you may have a loose solder connection either in the convergence circuit or the pincushion correction circuit. If you can't visually locate it, you may need a service manual and test equipment to track it down. I doubt that changing parts will be the cure if it is an intermittent problem.
