Question about Philips 9P5531C TV

1 Answer

Blue Glow I just bought this TV for a killer deal knowing it would have some problems. They picture isn't too bad for a 9 year old tv. But theres a definite Glow around Whites and blues but the picture isn't blurry. Doing Some research I found that I may need a Coolant Change or possibly replace the Convergence IC's. Could I get a few tips on how to do the coolant change. Also if any one could guide me towards which IC's I need, would be great. Thanks

    I'm fairly good with electronics as it is. I do alot of wiring for cars and computers. I'll be ordering some coolant from MCM 32 oz's total and ordering the Service manual. At the same time I might as well replace the Convergences IC's. Thanks for the Clarification Video-tek. For someone who has a decent amount of knowledge in electronics should this be about a one day job?

    I feel that after working on car audio for 3 years and computers for almost 10 I should be more than capable of changing out the coolant. I'll order the service manual and likewise I'll be ordering the coolant from MCM and draining all three projectors. Hopefully I can get this tv working properly!

    I will be sure to take pictures for you as I take it apart, and if only this coolant flush was as easy in a car! I'm ordering the coolant tomorrow and I'll be taking on the task hopefully next friday.

Chad, sounds like "FROGGY" coolant to me, Philips brand tv`s are infamous for this problem usually the green & blue tubes, you can confirm this by removing the back cover (carefully it`s heavy and has a large mirror attatched to the inside) turning tv on and look directly into the red lens, you will see a clear image, now look into green & blue and there probably very cloudy. Bad news is this is a very long, dirty, job and very diffiicult for a layperson, if you want to attempt it you MUST buy the service manual (any tv shop can order it for you) I would also advise you to NOT buy philips fluid as the **** they sell will become cloudy again (I use RCA cause it works and it`s cheap) good luck if you attempt it, I would advise you to calll a tech, video-tek

    chad, get the manual first, you`ll need coolant and the gaskets, be sure to THOROUGHLY wash out each tube with a bleach & water solution to kill the bacteria, (not mentioned in manual) mark everything as you dismantle it, try not to move the lateral magnets and yokes (mounted on narrow end of tube) or your in for a mother of a job getting it lined up correctly, I`ll be on here if ya need help video-tek

    chad, I`ve done this approx. 100 times, never had to do a red one so don`t bother unless when you look into the red tube it`s cloudy like the other 2, first time around it will take about 8 hours to do 2 tubes IF you don`t move the lateral magnets or the yoke, remember that the coolant is poison and be SURE to wear some kind of eye protection when you crack the 4 bolts because the **** goes everywhere, (no drain plug like a car) if you have a digital camera take pixx`s as you take it apart, gl video-tek
