Samsung HCL473W - Doesn't turn on

It worked fine one day and then the next it wouldn't turn on. I had a repair man come and he suggested that I spend my money on a new TV. He pointed out a large module with cards or smaller modules sticking out of it and said the whole thing could be bad or just one of the cards. He's quoting anywhere from $300-700 for the repair. If I new what the part was that is bad I would order it and install it myself, but he never gave me a write up of his findings. My TV is only 6 years old which I think is way too early to send it to the junk heap. Any suggestions?

    Set would not turn on...

    Repair man pointed out the Blue side cooling fluid has leaked out onto the board and done damage to the board...

    I've seen many questions about the blue side leaks. Seems like a known issue.

    Repairman said it would be $600-$800.00 to fix and closer to the $800.00.

Hi. Did the ngineer say that it was problem with convergence pcb ? To be honest the lil git hitting the screen is more likely to damage the screen than convergence. Try going in to the menu then convergence & adjust red & blue to try & get the crosses white with no coloured halo around. Post on here with results your model of tv is pretty straight forward I work for an indepedent tv repair shop the manuals are easy to get hold of thats if he even needs one. Chris..

SOURCE: HC-P4752W - IC Replacement vs Convergence Module.

The colors weren't lining up correctly on my HC-P4752W which is only about 30 months old. I did a little bit of research and got ahold of the people at http://servicemanuals.vstore.ca/ They recommended replacing the IC's as well as the IC resistors. I purchased the replacement parts from their site and made the repairs myself. I should mention that I didn't have any previous soldering experience. The repair was easy and a complete success. You may find replacement parts elsewhere for slightly cheaper but what you won't find is the prompt and detailed customer service that they provide. They gave me there # and said to call if I had any questions before or during repair. I took advantage of their services and got answers every time I called.

SOURCE: Samsung HL-S4266W 42 in. TV has a bad DLP module.

The part # all depends on which version of the set that you have. Take a gander round the side of your side. Right side, if memory serves. You should see a sticker with 3 lines. One for model #, one for serial and one for version.

On the off chance you don't see one, check around the left side of the screen and take note of the lamp code. Your version will probably be a PB01 or PB02.

Depending on the version, the part # changes. Either way, you're looking at about $200.00 for a DLP chip. That's just the chip mind you, not the DMD PCB that drives it, or the rest of the light engine that helps process that information. I have had, during the course of my career, replaced a DLP chip to address white spots on the screen and found that insufficient voltage from the power supply cause the issue in the first place, or that the light engine itself was a contributing factor.

If you were to replace the light engine itself, you would replace all three components here and guarantee yourself a solid repair. You would hit the LE, the DLP and DMD all at once by doing a light engine. Granted, the cost is substantially more, but it might be easier in the long run to swallow $600.00 for a completed set than to swallow $200.00 for a DLP chip that didn't fix the issue and now can't be returned. Plus, a light engine will literally take you 30 minutes to put in and be done. Maybe even less.

PS - Don't touch the surface of that chip. And when you remove the DMD, pull out the old DLP chip and insert the new one....you're going to have to have help. Someone is going to need to watch the screen while you manipulate the DMD--set on and running--to align it back to the aperture. Have fun.


Part #s: Version PB01 :
4719-001968
Version PB02:
4719-001981

My Samsung hlt5055wx/xaa has 2 green lights lit up but won't come on ? We replaced the picture tube 2 weeks ago and it has been working fine until I tried to turn it on today.


Your TV doesn't have a picture tube but rather a bulb. I would eliminate other possibilities first like cable connections etc first before looking into the set. Check all inputs with DVD or Bluray and see if it malfunctions across all inputs. If so it would be time to open up the set. If you are not comfortable with electronics you will have to bring it in.Really these sets are being given away these days and a repair should be considered carefully before spending any money.

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.

Black pixels in shading and back ground turning red


This is not a "rear projection" plasma TV for whiuch you offered solutions, It is the LCD Flat panel the Liquid Crystal Display a 40" Samsung. I do not think this problem is a dead pixel as that woulde be "black" Reading on the web I found only one post that appeared to be the same or similar and the person said somehing about "switching the red wire" Maybe it is a "stuck" pixel -- sticks on red once in a while. Like previously after the first time it occured it has not come back in three days now. Samsungs repair comes today i will cross my fingers.

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.

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.
