Samsung pcj522r Put a new blue crt in and now the manual conversion will work and you can tell the old one was bad, but the convergance sets a little to the left not straight. Would that mean that the crt electronics are bad in it?

Not really, its possible that the Convergence yoke rings may have gotten misaligned when installing them onto the replacement Tube. Usually you need to realign when installing a new tube.

Its the digital convergence unit. If that goes out you will not have any control over the convergence. I have seen many times where the convergence ICs were suspected to be bad, and then after changing the ICs the set still wouldnt converge. the magic focus is controlled by the DCU often the magic focus will work only part way, then other times it will go farther then back to nothing. The DCU is usually suspect if more then 1 color is out.

That sounds like a solder issue on one of the CRT drive circuit boards. Check the CRT boards for bad solder joints especially on the socket connections.

no but the board which is on the upper neck of the green CRT could its the velocity board which has an effect on all 3 tubes convergence.

No blue manual convergence - Samsung pcj522r


Thats a very strong possibilty the phosphorus may be burned off the CRT face. Does the blue project when powerd up and looking in from the raer of the set? Look into the blue CRT lens while its playing If you can see a clear picture I would think that you have some open resistors in the blue circuit, If you cant see a picture its time for a CRT. If you need a CRT let me Know I have a good source for them Used.

Samsung pcj522r shuts off randomly


samsungs have convergence ic that heat up and cause tv to shut off but most of the time the colors will be off. Alsp solder connections could cause this on voltage regulators.my guess would be convergence ics cost for repair is 250.00



thanks doctor video

Samsung PCJ522R Pictures is completely shaded with yellow


Everybody here seems to have basically the same problem so I will write a general fix for these Samsungs. First what you got is known as Convergence failure, A Ic or resistor, fuse or some other component has failed in the convergence circuit. So finding the service menu and trying to align the colors or spinning magnets on the CRT’s or a real bad idea of tipping a CRT or mirror would be the equitant of ripping the transmission out of your car because it had a flat tire. When the convergence fails no adjustment will bring it back, and if you do one of these stupid things then you have two problems. Now most of these Samsungs have an easily replicable board that all the convergence amplifiers are on. This can be found by removing the back and seeing if there is a board about 9 X 5 inches big and mounted to the CRT mounts, there will be 5 connector to this board. Now if your set does not have this board and instead has the two convergence Ic’s (these are about the size of a playing card and have the numbers STK392-040 on them) mount down on a board below and to the right ( this is known as the deflection board) this repair will not work for you. Instead you will need to component level repair the convergence circuit. But if you do have this separate convergence board the repair is fairly straight forward. Go to www.vancebaldwin.com or some other supplier and order BP95-00142E this is the convergence board. This board has been crossed several times through the years but this is the current version. Now once you get this board simply replace it making sure to get al the connector back in there original spot. The fire up the set and run Flash focus and for about 95% this will fix the set

Blue lens works, but has a weak projection compared to the green and red lens


The most common problem I have seen with these Samsung projo units is the blue CRT (picture tube) failing. They usually form algae on the face of the CRT which means replacement of the CRT or rebuilding it by a CRT rebuilding company. I wouldn't suggest the novice to pull the CRT out because if the wrong mouting screws are pulled you will spill out the cooling fluid within the face of the CRT and that will cause more problems.

Problem with Samsung PCJ522R 52": White is yellowish


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.
