I dont think you need a picture tube. If the audio still works when the picture goes out I would suggest checking the solder on the vertical output IC that could make the picture tubes blank out. Look for hairline cracks and resolder just to make sure. Let me know how you make out or if you need more info.

Pioneer 52" projection TV, SD-533HDS,


It is likely that the CRT's (picture tubes or bulbs) are weak. It is a major job to change and all three should be changed to make the picture like new. However, it is not costwise to repair this old of a TV even if you can get the tubes. I estimate the cost of each tube is at least $200 each. I would call Pioneer and give them your model number and see if they are available. Only a trained technician should change the tubes because it requires a lot of time and setting up of the tubes and other things.

You TV has a bad CRT, a red CRT by the sounds of it. This TV is rather old, perhaps 11-13 years of age? Your TV has given you many years of service and I do applaud you for the care you have given it and the TV for it’s reliable in your home. The trouble you face with a rear projection CRT set of this age is that you can’t just change 1 CRT tube and expect it to be reliable and produce a good picture. All 3 tubes should be replaced, as they have all aged the same. The lives of these tubes are only about 7 years. A tube is not any easy or inexpensive repair on any RPJ TV. When you are faced with the cost of 3 tubes, which may not even be available in the market place… You should consider retiring this old friend and keep the manufacture in mind as you make a new purchase.

I need a picture tube for my mitsubishi vs-5051 40in projection tv, how much do they generally cost? whats a good website or store in my area of manor texas?


Honestly, sorry to give you the bad news and I'm one for trying to repair then throw out but, buy a new 42" flat panel it will be a lot cheaper. Mitsubishi quite making these size CRT's over 5 years ago and a replacement tube would cost more than buying a new replacement 42" TV.
My thoughts is that this 5051 is over 13 years old.

How much would it cost me to replace the picture tube for rca big tv screen that i got it for free ? where do i buy it at ?


A CRT (picture tube) for an RCA projection TV will cost $300-400 If the TV is more than 4-5 years old, you'll likely have to replace all 3 CRTs to obtain a watchable picture. Its probably not a good idea to spend that kind of money on a "free" TV.

Bad picture


A 10 year old Rear Projection tv is usually at the end of its life. No such thing as "fluid". Best advice, get a new TV.

Philips Projection TV Bulbs need changing


Buy a new television. The "bulbs" are actually small picture tubes, also referred to as CRT's or guns. There are three of them, Red, Green and Blue. The cost for the tubes alone will probably exceed the original purchase price of the television. If the new tubes do not have the lens assembly attached, then you will need to transfer the old ones. This involves draining, cleaning, and refilling the coolant chambers. Once installed in the set, there is a series of mechanical and electrical adjustments required, to get the picture aligned or converged. This procedure is not recommended for the inexperienced. If cost and time are not an issue, then everything can probably be found on the Internet. Simply search the web for your model number. You will need the remainder of the model number first. There are at least eight models starting with 46PP9302. You are missing three additional characters.

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
