Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television

1 Answer

Philips 60pp9202. When power is turned on the blue CRT arcs and then the TV shuts down (the arcing is in the tube above CRT board). Also the convergence reistors are burnt (3149 and 3150). I replaced the resistors and turned power on and they burnt again.

Picture is getting darker all the time.I updated the software.Still same problem, Adjusting personal prefrences doesnt seem to help.


Check the CRT fluid in the blue and green CRTs to be sure it is clear and not cloudy. A common problem. Since you mentioned the problem was gradual over time, I'm guessing it is the fluid. This would be more obvious if you were seeing like a frosted look to the picture or dark areas and bright areas, which are caused as the fluid clouds up. The picture tends to be more red as well.

Your alternative is to try adjusting the screen voltage of each bulb on the focus block of the tv. I think with an older Philips the screen/focus block is in the back of the tv. This is the little black module with six knobs coming out of it. Three knobs are for focus, and three are for CRT voltage.

Follow these steps:
Note: Be careful here, as hazardous voltages are very near by. Only use one hand inside the tv.
a) With tv turned on, go to a blank input screen
b) Very Slowly, turn the screen voltage up carefully for each CRT until you see arc lines of that color on the screen. Slowly back the voltage down until the arc line disappears. Do this for all three.
This should help with brightning up the picture if it is a voltage issue.

If the fluid is not the issue, then likely the flyback transformer is slowly failing and not providing enough voltage to the CRTs. Adjusting the screen voltage would help in this case.

MY SONY DOESN'T WANT TO START..IT WILL SNAP TO TRY AND COME ON...THEN TURN OFF AFTER ABOUT 5 SECONDS..HELP?


The snap you hear is likely from the high voltage in the set. The worst case scenario is that the picture tube (CRT) is shorted and is arcing internally causing the set to shut down. There are other less expensive possibilities such as the flyback transformer which can also fail in such a way as to arc. You may be able to see through the top ventilation slots in back as you power the set. The neck of the tube extends back into the rear cabinet and you could possibly see a flash inside the tube neck if it is arcing. I would have to recommend you have a technician check this problem to diagnose it. The tube, if it is defective and out of warranty, would exceed the cost of replacing the TV. Check your warranty as the tube generally has a two year warranty and other parts one year with 90 days on labor.

Ed did you change the yokes when you put the DPTV series CRT into the PTV chassis? If not its most likely the vertical output or the Horizontal output that got destroyed. If you changed the yoke its most likely the HV generator.
On the DPTV chassis that should shutdown the vertical deflection which would leave audio working worse case scenario would also be the HV generator and Horizontal output.

First of all you need to find out which CRT leaked and replace it before any other repairs are done. The clear liquid is conductive and has done damage to the CRT board or boards.

HD52W59 CRT Arcing


Blue Crt arching... on the board or on crt? most likely if it is arching you are right in suspecting the tube. These tube are around 240 dollars per tube and then i would sugest replaceing crt board. I work on alot of these at the shop. bottom line if there not under warenty then really not worth fixing. these set cost about 800 new it would cost around 500 to fix. crt replacement of these set is a very involved process. I think almost ever screw in the set has to come out and then after you get it all back together. theres the alignement issues.. im not saying dont do it just if you like a challenge go for it.

Replacing CRT neck socket after arcing problem.


Hi.

Don't know what happened to the last post I sent you its disappeared.

What I think you should do is definately replace the CRT white socket (tube base plug).
You can either take the CRT number from the label on the tube & put it in to google then search for Crt base plug.
Or see if there is A repair shop local to you who can order the tube base for you.
Are you definately sure the arcing is external to tube & not happening in the tube neck ?
Is the CRT made by LG / PHILIPS. These are notorius for for arcing over internally I must write at least 1 A week off for this problem.

If you can still run the set try tapping the neck of tube with screwdriver handle if pic flashes or goes predominately1 colour you are looking at the tube with internal short.

If this is the case there are ways of trying to get rid of the internal short let me know what you find ?
