Problem with Samsung PCJ522R 52": White is yellowish
Hello tech gents! Gradually, over the years, my 52" projection has started losing white in the picture. I hardly noticed it, until my visiting brother pointed it out. Now, no matter what it is, when something comes on the TV and has white in it, it's yellowish. For instance, looking at a wall on a TV show, is yellow.
I tried taking the back off the TV, and cleaning the mirror and lenses with rubbing achohol, as a friend suggested, and although they are now clean, it still hasn't fixed my problem. I tried going into the menu and adjusting the tint, but that didn't help either. I also went to convergance, but it's only allowing manual, and only Red and Blue.
Does anyone have any suggestions? I want to hold out for another 6 months before I buy a new HD, but I was planning on putting this in my son's room.
Any help would be appreciated!

It is possible that you may have had a leak in one or more of your CRT coolant chambers, see:
Product: Projection TV Bulletin # PJT01-001
Model: PCJ, PCK and HCJ series Bulletin Date: 6/1/01
SUBJECT: CRT Leakage
Background: When repairing set for CRT leakage, check if CRT has Expansion Chamber installed. If not, install Expansion Chamber on all 3 CRTs. Production during November 1999 ~ September 2000 will need Expansion Chamber installed.
Rear panel will indicate production date.
This can also leave a residue on your printed circuit board that would have to be cleaned off to prevent further corrosion and leakage currents.
Hope this helps.

If this is an old 52 projection with bad color your oil in the tubes may need to be changed, focus & screen can be adjusted to improve picture. Changing oil is something a tech defintly has to do. Call a local tech & get pricing. Then u can weigh your options. Also tubes may be weak. If they need to be changed probably won't be worth it.

Sorry...I got out of television repair before ever working on projection screen sets, so I have no idea.
I know there should be three tubes, one for each primary color, but I don't know if there is some way to discharge all at one time, or individually.
If Fixya has me listed as a projection tv expert, then I apologise, I am going to check that now.

Samsung rear Projetion Tv Model No. PCJ522R
i was cleaninthe inside when i spilled oil on half of the board power supply,when the tv is connected power button is light up but wont turn on,what can i do?
It sounds like at least one of 3 "IHVT",s popped. in short, a "IHVT" is a high voltage transformer. It will have to be replaced along with any other parts that were damaged in the process.
They do produce a strong odor when they pop!!
It is repairable but at a price. there is a good chance that parts will have to be ordered.
you might consider buying a new LCD HDTV instead of fixing this one.
if you look into the blue crt it will be very foggy..the coolant in the crt needs changing.
you may want to contact a local tv repair person for more advice and coolant changing procedures....john
