Adjusting the crosses can be a pain, because adjusting one will affect the cross next to it. try to pick a pattern, like working from the center outward might help. You can go around several times, don't try to get them perfect the first time, just closer. You can do this in the user menu.
If your convergence ic's are no good they might not hold an adjustment.
be sure to purchace OEM ic chips from reputable online store or repair shop if replacement semiconductor have bright white lettering good chance there aftermarket spend the extra money dont buy cheap ic chips check the datasheet and conpare specs if there not the same as the stk392-120 specs 18 pin sip 44v 4a 3.0 deg c/w, i used stk392-150 that where aftermarkets luckly lasted a year the resistors are pt#rmo 1w 6r8 j or philips #212010690297 12 to be exact been there done that the stk394-160e are custom made for hitachi sets wont work in your philips .
My 60pp935217 had the convergence issues as others have described, so I ordered the STK's and installed them. Problem solved. Now the picture is not shaped correctly. When in the convergence mode the crosses on the right of the screen are to far up, and to the right, for the top half of the screen. the bottom right part of the screen is almost to far down to see. I have the service manual but am not sure what settings to mess with. I believe I need a screen template, and then need to make adjustments in the convergence alignment mode, starting with green. I have tried to make some adjustments to the green, and it will not adjust. What to do now?

it sounds like you didn,t replace the 12 6.8 oms resistors when you changed the ic- chips when the ic-chips go bad the resistors burn also check the blue resistors near the ic chips there will be some that are discolored the resistors are numbered on the board (3149 thu 3160 ) replace them , dont replace just the burnt ones mcm electronic has them , the philips pt#212010690297 there ( blue - gray -gold - gold ) color bands good luck nascarfan
I measured the resistors in circuit and they measured 3.5 ohms. I figured the were in series so that was an OK reading. I looked at the entire circuit visually and no parts seem have have let the smoke out so they should still work. But I have all day, I will do some double checking.
I took all 12 of the resistors out of circuit and measured them, 6.9 -7.2 ohms. picture is still distorted.
I have found that the green will not change when I am in the Convergence Alignment mode. The manual said this should never be changed without a screen template, well I was messing with it anyway and I cannot get it to move at all. don't know if this piece of info helps. I hope so.
But also double check wires/connectors, including wires at the back that may have slipped under the chassis, continuity (traces) to and from conv. resistors, stk's for solder bridges.
You shouldn't have to replace all resistors, just the bad ones. Make sure the replacements are the right type flameproof/metal film/fusible not ordinary carbon.
6.8 ohm Convergence resistors should read about 3.4ohm in circuit.
kickercrv , be sure the ic-chips are OEM replacements if the pt# number on the part is white-bold print theres a good chance there aftermarkets the printing should look like your orginal chips , i bought stk392-150,s from electronix last year because they were cheaper only lasted a year nfg, i just bought stock 120,s for my tv from www.prelcoelectronic,s they are OEM parts i talked to bill at prelco asked him about the stk394-160 he said dont use them in my philips there not for the phlilps tv sets, i replaced the 2 ic-chips & the 2 burnt resistors this time & had to take ssb board back out & install the other 10 6.8oms resistors because i couldn,t adjust the red-blue multipoints w/ my remote, last yr i did the 2 ic,s & the 12 resistors & did the adjustments w/the remote was perfect also check the spec,s to make sure they are the same as the 120,s, i also had to adjust the color this time to get the picture right. i bought the resistors from paul @ [email protected] they were the correct resistors and a decent price i found him from another site nice guy. nascarfan

hey also if you take off the upper cover go in to the convergence settings w/ your remote adjust cross,s off a little then adjust them at the black box on the crt bracket the lower knobs are for focus, adjust while looking thu to screen do that thu the convergence menu then adjust the cross,s so they line up then store the settings see if that helps correct the fuzzy picture i also had to adjust the color down a little bit on my set . i,d like to somehow install a cpu fan on the heat -displacer or on the back cover too remove some of the heat- buildup trying to investigate that best way to power it so it would run when tv is on would,nt hurt .
problem is getting worse. I installed the STK392-120. TV looks exactly the same as before, but now if the TV is on for about a minute or longer then turned off, the TV will not turn back on until all components are room temp again. It will try to turn on but it powers itself down, I am guessing to prevent something from overheating.
The picture is so far out of convergence that the crosses used for convergence are not visible on the screen, the crosses on the left side of the screen are totally off the screen. I have read every page of the service manual but without the green having the ability to be adjusted, I believe my TV is dead. there is nothing in the manual about if the green does not adjust anymore.
I could probably take some pics of how bad it looks, not sure if that would be helpful or not.
do you think the liquid is bad? forgive me I dont remember what it is called. or that you touched/mis-aligned the rbg lights? Just a suggestion. a tiny movement could throw the alignment off.
2) Buy the exact same chip that was in your set. Magnavox sets typicaly have STK329-110 or STK392-120. Don't substitue, upgrade, etc the chips no matter what you read. If you put a different chip in the set it will most likely smoke the resistors.
3) Replace all 12 of the convergence resistors. Every day a dozen or more people complain that their set is still broken after replacing the convergence chips. The number one reason is that they did not replace the resistors. Replace all 12 even if they don't look burnt. Testing with a meter is not reliable because the resistors often fail once under load.
4) Check/Double-Check your soldering. Make sure its clean and does not have any bridged connections.
have an old maggy, the RK8519 AK04, IT has no STK IC's anybody have any old info for this beast?it uses the seperate PNP & NPM transistors as a push pull amp circuit but this monster has a problem on the power board.

Can someone tell me the two numbers on the circuit board that is for the 6.8 resistors that need to be changed when you change the stk392-120's for a 60pp93-5217 Phillips rear projection hdtv. Thank you, Gary
mr.g said: I just recently fixed my convergence problem and all colors line up, but now the picture is fuzzy. Looks like its out of focus a bit. Anyone know how to focus this tv. Is there a certain voltage to set each tube at? I am trying to do this myself if it is all possible. I am working on a Philips 60PP935217 TV. Mr.G
I am replying to you with a question since you just fixed you convergence problems. I own the exact Phillips you have and I am replacing the stk392-120 ic's. I was told that you should also replace the (two) resistors that are part of the convergence as well. They are 6.8 ohms and are 1 watt. Do you know what numbers on the circuit board is the two resistors that need to be replaced? I think 3151 and 3152? Just a guess? Do you remember? I own a 60pp93-5217 Phillips hdtv. I beleive it is the same one as yours. Thanks, Gary
all the 6.8 oms resistors should be replaced , can you adjust all of the convergence settings with the remote ? red-blue-multi-point ? if all where take-off upper cover go into converge settings adjust cross hairs off abit if there fuzzy there,s a black box attached to crt bracket /top three adjustment screws are for color / bottom are for focus , adjust red so the cross-hair is crisp then go to blue convergence do the same, the black box is marked r-b-g i did it this way didn,t have someone to watch front of the tv seemed to worked for me, make sure you can do all the convergence first if the red&blue multi-point wont adjust you,ll have to change the other 10 6.8 oms resistors first there numbered 3149 thu 3160 then do the focus adjustment .
I finally fixed the whole Multipoint problem, I opened the back up and looked at all of the lenses. Seem to be find until i spotted some leaking.. Then i found that the rubber washers wasn't put on right. The guy that fixed out tv last time put it on wrong. So I added some of that liquid, and fixed the washers. worked fine until few months. I called the repair man and i had same problems.. Multipoint, darkness and so on and on. Apperently the fluid i put in was a different mixture and it created bubles. I cleaned it out and I filled it up with Baby oil. Baby oil can be used too u know.
There is a square box in the back of the set. It has 6 adjustable screws for settings. There are three for focus and three for color. The center screw for color is the green.

I bought STK392-150 as replacements, could that be doing it? should I buy STK392-120? There is nothing else wrong that I can find.
You should use genuine stk392-120 for 60pp935217 according to the manual.
http://www.techlore.com/forum/thread/22659/STK392-XXX-Spec-s/
But also double check wires/connectors, including wires at the back that may have slipped under the chassis, continuity (traces) to and from conv. resistors, stk's for solder bridges.
You shouldn't have to replace all resistors, just the bad ones. Make sure the replacements are the right type flameproof/metal film/fusible not ordinary carbon.
6.8 ohm Convergence resistors should read about 3.4ohm in circuit.
thanks for the help, I will order up the 120's and try that.

If you do the following it will work...If you don't you are wasting your time and money.
1) Buy only Sanyo brand chips from B&D ( www.bdent.com) , Acme (www.acme-sales.net) , or Tv Repair Kits (www.TvRepairKits.com )
2) Buy the exact same chip that was in your set. Magnavox sets typicaly have STK329-110 or STK392-120. Don't substitue, upgrade, etc the chips no matter what you read. If you put a different chip in the set it will most likely smoke the resistors.

in the service manual it explains how to do electrical focus and static focus
You may want to consult a technician before doing so.

Thank you. I just thought that there were 2 main resistors that had to be changed when changing the ic's. for convergence problems. Gary
