Question about Samsung HCL4715W 47" Rear Projection Television

2 Answers

Anyone need any parts for the HCL4715W? Parting mine out.

Something burned out on the board with the IC chips and I got a new TV. I took all the electronic components out of it and I have all 3 guns intact. Let me know if you need any parts.

I also have a spare brand new STK392-040 chip, i bought 2 when mine went bad but only 1 needed replacing. Convergence board should be good. I also have a spare brand new remote for the HCL4715W.

All parts are sold as is since I have no way to test them. Make an offer before they go off to the e-waste recyclers.

Its almost always a convergance inverter that has burned out. The IC chips as they are called aren't too cheap, Even the repair shop would suggest a new tv as a cheaper route in the long run. To make your set reliable again the convergance board needs to be rebuilt with all new chips, and pico fuses.

I got a Samsung HCL4715W from a neighbor and did not get the remote. I turned the TV on and the red lamp did not come on but when I pushed the menu button all three lit up. It also looks like it is not...


Hi , first thing is check for leaks coolant in all 3 tubes. It is a very common problem in Samsung projection TV. This means, if you have a leak, it makes no sense to repair your TV, isa big money for parts. Another possible solution would be convergence board is damaged, two STK 392-040 IC's number; also has associated resistors that can be opened or burned. Be careful, Try to open the TV and watch these two important details. If you have further questions, do not hesitate , I will be here.

I was watching my HCL4715W TV and the picture


It sounds like one of the convergence Ic chips is bad---you will need to locate and replace both of them and look for any damaged parts around them; there usually are two pico fuses in this area, one for each IC. The fuses do not look like glass fuses--they usually are green or orange in color and will have the amperage marked on them and on the top of the circuit board.

Samsung three colors on screen, out of focus #hcl4715w


It is a convergence problem. The IC's (integrated circuits) or STK chips or the "guns". You have a red,and blue, IC's that provide all the colors. When the colors are out of convergence, you get ghosting or what looks like 3D pictures. I haven't been able to locate the part numbers for the IC's or STK chips but have located a convergence board. No luck determining if IC's are included (a phone call first to verify) but if they are, would make life much easier for you to install. Part # is BP95-00415H http://jr.partsearch.com/Part/Samsung/Samsung/BP9500415H/New.aspx?ModelMfgName=Samsung&ModelBrandName=Samsung&ModelNumber=HCL4715W

Typically, IC's cost around $10 or less. here is a link to a guy who provides pretty good instructions on replacing the IC's along with pictures.

Convergence gone bad on Samsung HCL4715W


you can test the Is for having the proper incoming voltages and then checking to see if they have the correct output voltages. You willnee the service manual with schematics to be able to test all the voltages for the pins on both ICs. Do you have the servicemaual? If not you can get one at the following link they email them or provide download link depending on the size o the manuals

Have a philips magnavox 8p6044 c102


Hmmm... I dont know where to find those CTR Circuit boards I'll post my general post for you about what I know it has links to the manual and some other sites it may help.

how bad is it burned, did some chips go or just the copper circuit board tracers. you can use circuit board wire and solder it from point to point,
I had somewhat of the same problem with my IC board, I had a bad portion of the board where I had to build a new copper routing with circuit wire, the copper burned off when the resistor failed, you may need to do a little Frankenstein work on your board as a last resort... remember use a low 15 watt soldering pencil, use leaded solder, and USE flux!
however with all my work, I got it running but the IC board is still not running perfect. if you decide you cant fix the TV I would love to buy your IC convergence board from you.
GOOD LUCK! hope I helped...

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted pictures on, check out page 3

Where I got all my parts that worked:
Suburban Electronics http://www.suburban-elect.com/

Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads



What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux


BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com

How to remove back of Samsung HCL4715W 47 in rear projection TV


the screws are identified by little arrows pointing to the screw holes. However I would be surprised if its the convergence board most times its the Convergence ICs located on the sub board

Magnavox big screen will not power on button blinks but wont turn on


Need model number really, but sounds like a bad SSB module(small signal board). It would have to be replaced and depending on the model they can be expensive.
