Question about Philips 51PW9303 51" Rear Projection HDTV-Ready Television

Open Question

Green Tint Over HD Input

I just recently replaced two stk-120's, and two small resistors (6.8 ohm/1W/5%) on my 51PW9303. Now, the green is back to normal and the set looks great.

However, when I go into my HD Input (with my xbox 360), I get a green-tinted screen. I went into the Service Mode --> GDE SAM --> Geometry and noticed that "Fast Blank" is set to 1. If I set it to 0, the problem goes away.. but there's no way for me to save it.

I tried shutting off the set both by remote and on the tv itself. I've also tried unplugging it after initially shutting it off, and another time I unplugged the set after I shut off the TV. Each time, I left it unplugged for a minute.

What is the problem here? If it is the "Fast Blank", how do I get the 0 option to stick? I feel so close, yet so far...

Thanks in advance!!!!

SOURCE: Screen Green Tint

Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.

SOURCE: Green Tint Over Entire Printed Picture

I had a very similar problem and found out that the problem was the quality of paper I was using. Remember, a photo printer is expecting high quality results. Cheap, low quality paper will not accept the ink as well as higher quality paper. I can't guarantee this will solve your problem but I have not had any green tints since switching to a higher quality photo paper.

I have a hitachi 43FDX15B RPTV It appears to have a convergence problem, I've read about replacing the stk IC's but which resistors need to be replaced and what are the values on the DP15k/08 Board?


This model uses two of the STK-392-120 CHIPS and here are most of the usual resistors to suspect or check:

Hitachi AT03411S RK43 RESISTOR Hitachi AT03608S RP22 RESISTOR Hitachi AT03195S RK46,RK54, RK62 RESISTOR, 1.8OHM 1W Hitachi AT03857M R815,R865 RESISTOR, 1/2W 100 OHM Hitachi AT03191S RK50 RESISTOR, 1W 1.2 OHM Hitachi AT03197S RK50 RESISTOR, 1W 2.2 OHM Hitachi AT03199S RK41 RESISTOR, 2.7 OHM 1W Hitachi AT03202S RK42 RESISTOR, 3.3OHM 1W Hitachi AT03204S RK58 RESISTOR, 3.9 OHM 1 WATTThe RK ones are all marked on top and bottom of circuit board---usually if one is bad you will be able to see it is discolored---all are very low value and should read open or good only.

This is a fairly easy set to do this on---the whole convergence board (right side from the back view) is held in with 3 screws and an assortment of plugs--3 plugs are identical (convergence yokes and you need to mark so you get each back in same place)

A row of black snap plugs on the left side and with the screws and other plugs removed the board will lift up and out of the set.

DON'T waste your money on one of the "kits" being sold on the net---you can buy a pair of the chips for about 12 dollars on Ebay and usually only one (if any) of the resistors will be bad---those kits sound like a good idea but at 50-80 you are buying things you will not likely need to repair the set.

Let me know if you have any questions and if this information helped you rate this solution as I do this here for free.

Red blue and green lines on top on phillips hdtv. What can I do to fix it.


1.) This sounds like a convergence problem--with the original remote go into the customer menu and select convergence--see if red or blue will not move in some direction.

2.) If some color (red or blue) will not move in some direction--you need to replace both of the STK-392-120 CONVERGENCE IC'S THAT THIS SET USES along with any of the green 6.8 ohm resistors around them that are discolored(bad).

3.) With the back cover removed the chips are on the left large board on two metal heat sinks with fins--they are black and about 2 1/2 inches wide and 1 1/2 inches tall and the STK-392-120 is printed on the face of them in white. The resistors are in front of the one near to the front of the circuit board and left to right around several plugs there(convergence yokes).

4.) You can buy both chips on Ebay for about 13 dollars plus shipping; If you are able to do this repair you can save a lot of money---after the chips and or resistors are replaced you need to go into the Convergence Tech mode(I can tell you how to access it) and adjust the convergence in first the regular non Hd and then in the Hd.

5.) Most shops TRY to charge 300-400 for this kind of repair--I have done hundreds of them here for 200-250.

6.) If you are not able to do this repair shop around your area for someone who can do it---if a shop says "It has to go to the shop" keep looking----any good tech can do this repair in your home in about 1 hour.

7.) If you have any questions or need advice reply to this posting.

I do this here for free so if this information has been helpful please take a minute and give me a vote here-----I am here to help people.

I have a Hitachi 53FDX20B and the picture is looks stramge


It is not your Picture tubes that are bad, it is your Convergence IC's. The IC # to use is STK392-180. These are better than the originals, also invest in these resistors: 1.5 ohm 1w,,,1.8 ohm 1w,,,2.2 ohm 1w. (watt). I would by 4 each. Your soldering skills will come into play so roll up your sleeves and go to work.....Good luck ! and let me know how you do.

I have the mitsubishi 55711,i have a double image


This is a V-21 Chassis common, with these symptoms, for failure of the convergence amps. This set uses two STK 392-110 Sanyo amps mounted on a heat sink and hard to miss. They're a 40 pin ic about the size of a half pack of cigarettes.
It has also been my experience that two or more of the yoke return resistors need to be replaced, most commonly R8c21 and R8c22, both are 3.9 ohm 1w but test all of them for reliability.
Hope this helps!

Is the power supply completely dead ? If so with this model of power supply its very common for the resistor 3318 on power supply to go out. Causing the power supply to completely die. Take out the resistor 3318 its a 470 Ohm 1W resistor. check it if it doesn't read around 430-530 Ohm Its gonna be bad ( most likely ith will read in the mega ohms. Replace with a 470 Ohm 2 W resistor. Also check power supply for cracks

Convergence problem???


Check the resistors by the STK ic's, should be 2.2 ohms. Under the heat sink, also check the 1.8 Ohm 1W, fusible resistors found around the area as well.
Good Luck.

Convergence problem


That unit has a convergence repair kit that should fix most problems. Order it directly from Hitachi p/n# X480295. It contains: Rk42 3.3 Ohm 1w Rk46 1.8 Ohm 1w Rk50 3.3 Ohm 1w Rk54 1.8 Ohm 1w Rk58 3.9 Ohm 1w Rk62 2.2 Ohm 1w Ik04 Stk392-150 Ik05 Stk392-150 And I would strongly recommend testing all the resistors in that circuit for change in value. Are you using a good heat sink compound on the STK's when you installed them? That and ordering the japanese knock-offs for STK's are the two most common critical mistakes made. Originally that unit had two STK392-110's for conv. amps. Even Hitachi recommends subbing to a STK392-150 or 180 for greater reliability. You do realize that for the cost you have after two failed attempts you probably could have taken this to a reputable shop and watching the ball games now. :) (no disrespect intended) Good Luck!
