Question about Philips Magnavox 51MP392H Rear Projection Television

1 Answer

51MP392H17 Convergence Well I tried to fix the convergence on my Magnavox 51MP392H/17 and replaced both STK392-120 pieces as had been suggested. But it didn't do much good, and is as if I hadn't replaced anything at all! The blue converges fine, but the red exhibits the same inability to converge laterally. Further, I've looked all around the PCB to find those 6.8 ohm resistors to replace, and they simply aren't any there. Could they be hidden? Perhaps this model doesn't require them? Could the problem be upstream or downstream from the IC's? Other ideas or things to check? Thanks!

Yes your model has the 6.8 ohm 1watt resistors there are 11 of them often marked as 6R8 1wJ instead of color bands. They are resistors 3149 through 3160 you can get replacement resistors at the following link.

My tv is a magnavox and we bought it about 3 years ago and it is now showing like a double picture the color is hazy and pinkish looking the model is 51MP392H/17


The problem of your unit is the convergence. Try to adjust it using the original remote control in the setting menu, then goto the convergence section adjust the red and blue convergence, you should move red and blue UP, DOWN and LEFT or RIGHT, if you cannot move them far enough the convergence IC is defective, replacing this IC will restore the original setting of your tv. This convergence IC is attach to a large aluminum plate it is the heat sink this IC has a marking of STK-#### followed by numbers, remember be careful when replacing this IC you may accidentally tampered or damage the PCB and cause much damage to your unit. Or you can contact a technician to do it for you and save you from stress good day and best regards. Try to check this link for the convergence http://www.google.com.ph/search?q=convergence+ic&hl=tl&sa=X&tbm=isch&prmd=ivns&bav=on.2,or.r_gc.r_pw.&biw=798&bih=472&ech=1&psi=JZdtTvDCPIe4iAe72sTABA.1315804977740.3&emsg=NCSR&noj=1&ei=MpdtTpa4OKKSiQfBpcjGBA

No.Should cost u like $300-350 for parts and labors.Get it fixed any local tv shops can fixed this problems,very common problems for DLP CRTS tubs design projection tvs Tv have a problems known as a convergence problems,it is dead.The tv convergence board it is dead,that why ur tv picture colors lines R,G,B mis alignments,have pictures colors shadow or 3D pictures look alike.The tv convergence board must have it parts replace like 2 STK convergence ICS and some or all of it resistors to fixed the convergence board to solved convergence pictures problems.

The convergence ICs and resistors have failed. You will need to install a convergence repair kit. The Phillips DPTV305 chassis convergence repair kit is the correct one for your magnavox. Its available at www.tvrepairworld.com and the kit contains the 2 ICs and resistors and the CD with repair instructions.

Magnavox


Need more info, does it click on and off, make any noises, was the picture going blurry, did you just move it, was in built into a wall where it wouldn't get air to cool???

Here is what I know about the 51mp392h this is a general post below I used for some other peoples fixes without more info on yours I suggest reading thru the below and links and add more info to your post so we can trouble shoot it.
51MP392H/17

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!

Manual Library you should find all you need here:

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

Wavy lines


I have the same problem with this tv. i took it to a tv repairman, and he told me my convergence circuit board was the problem. the circuit board itself is about $300 and the labor to fix it is another $150. So i never got it fixed, cause it's just too expensive.
