I am Curoius about the sony model number

Some sony televisions has model number containing with "XBR" as I have read up on the operating manual.

I have the Operating manual for the following sets

they are:

KV32V15
KV32V26 AND,
KV32XBR37

According to the spec on the sound system both KV32V15 and KV32V26 has 5 watts per channel and the KV32XBR37 has a whopping 15 watts per channel.

What else differnce between an XBR and non-XBR?

XBR was (is?) Sony's top of the line, they generally have all the features their regular sets don't have including picture refinements.

There are folks here that can give you much better information that I can but I think that's basically correct.

I had a KV27XBR10 from 1990 to 2005, it had the best picture of any CRT set I ever owned.

My sister and her now ex-hubby bought a KV20XBR in '85 or '86. For it's time, it was an advanced TV over most of what was on the market. It had stereo sound with detachable speakers and every kind of A/V jack known to man on the rear. One could even connect a computer to it. That set saw heavy use until the mid '90's, when the CRT got weak.

The KV-20XBR and the KV-25XBR came on the market in 1985, and they were the all-in-one replacements for the Sony Profeel KX-1901/KX-2501 monitors and their separate tuner/switchers. They had incredible performance for their time, even better than the Profeels.

I had one of these, I had the KV25XBR. Beautiful picture. Used tilll 2004 when I gave it to a friend who lost everything in thier home.

As said, it was the "loaded" model of various years. The first ones (KV-20XBR & KV-25XBR, and KP-36XBR) had digital comb filter, multiple RGB and composite inputs, and built-in antenna A/B switch, and all kinds of bells & whistles. They also had a very fine pitch tube, which as Freakaftr8 said, has one of the best pictures of any TV all time. Later however, the CRT was the same from the cheap model to the XBR.

Sony recently put out a notice advising people to stop using there sets made before 1990, due to "risk of fire":

http://www.sony.jp/products/overseas/contents/support/information/notice_100610_en.html

I think I'll still hold on to my old pre-1990 Sony's anyway...

I like the way they DONT tell you what the defective part is. I think I'll keep my old Sony's too.

I smell a class action liability lawsuit.

Are these the sets that use a whole swath of ceramic high wattage resistors and that dreaded "silicon controled switch" in the power supply?

My conspiracy detector indicates however...

They opened a can of worms by making that announcement. thats for sure.

I like the way they DONT tell you what the defective part is. I think I'll keep my old Sony's too.

I feel the same way. I have a mid '80's 19" entry level trinitron that I got in around 2001 from a TV shop that was about to toss it. I replaced the bridge rectifier, a resistor, and a fuse and the TV still works fine to this day and I see nothing out of the ordinary that would scare me into thinking it might catch fire. The only thing that might go up in flames would be the flyback transformer; and, there's a risk of that with any CRT set. I think this is more of a stunt to scare people into getting rid of their old TV's.

What is different in a KX-1901 or a KV-20XBR bought at a PX versus one bought in anywhere else?


From their website http://esupport.sony.com/perl/support-info.pl?info_id=606&template_id=1&region_id=1

Notification to stop using Sony color CRT TVs manufactured prior to 1991 that were purchased at a foreign U.S. military exchange Sony has learned that Sony CRT color televisions manufactured prior to 1991 that were purchased at foreign U.S. military exchanges, contain a particular inner component that may suffer age deterioration following very long term usage and thus overheat. This overheating may, in rare cases, cause the component to catch fire and result in a burn to TV set and at times damage to surrounding property. As a result, Sony would like to ask you to stop using these televisions.



Only Sony televisions which meet all three of the following criteria are affected:



Your television model must be listed below: KV-1215 KV-1484P KV-1712D KV-1946R KV-2156R
KV-1216 KV-1513 KV-1713 KV-1955R KV-2182P
KV-1217 KV-1515 KV-1743R KV-1967RWP KV-2184P
KV-1221R KV-1541R KV-1746R KV-1982AEB KV-21VX1P
KV-1332 KV-1542R KV-1920D KV-2073R KV-25XBR
KV-1356R KV-1543R KV-1921 KV-2092AEB KV-27VX1P
KV-1370R KV-1545R KV-1922 KV-20XBR KV-27VX1PH

KV-1442AEB KV-1712C KV-1943R KV-2145R

Note: The model name is usually located on the back of the TV.

The television was purchased overseas at a foreign U.S. military exchange.
The television was manufactured before 1991.
Note: The manufactured date (month and year) is located on the back of the TV.

IMPORTANT: This issue does not apply to any of these models that were produced, sold, or marketed in the United States.

Sony supports a national network of e-Recycling Drop-Off Centers as part of its Take Back Recycling Program. To dispose of Sony televisions covered by this notice, please visit www.sony.com/recycle for details or contact your local waste management and/or recycling center for a drop off location near you.

Please contact Sony at (888) 649-7669 with any additional questions or concerns related to this matter.

Now I really want to know what part this is

I'm guessing this can either be the flyback or those big resistors...

Since it's sets sold overseas on Military bases perhaps something related to Dual Voltage operation? if they had such a feature that is?

I see several US-only models in the list, so those wouldn't be dual voltage.

Here, off the top of my head, would be the best guesses at the part causing the risk:

Degaussing thermistor (gets bad connections and keeps cycling on/off, causing AC line voltage to burn a hole in the board)



Flyback (most likely cause in my opinion... Arcs, smokes & flames, but usually blows the fuse before starting any fire)

HVR block (can arc and flame out like a blow torch, but seldom seen in Sonys. More likely in RCA CTC-169 projection version, etc)

AC line input choke (can arc and cause AC line voltage to burn holes in the board)

With that said, ANY, and I mean ANY item which plugs in, or has batteries, can cause a fire. So can Coke bottles, fancy crystal decorations in the sun, etc etc etc.

If everyone used common sense, there would be little to worry about. If you leave your 1984 Sony TV, or any appliance running unattended in an empty house, you probably are asking for a problem sooner or later.

I think the clue here is what design / part change Sony made to there TV's after 1990.

At least to me, it seemed like every sony had significant chassis changes, while alot of it remained the same as well....

I agree with Charles, you can't mandate or design in common sense. On the overseas list, there is a swath of US models. Notice that a lot of these aren't on the US list.

Before 1990...a LOT of Sony sets were "hot", in regards to the power supply, (like my little 1985 model KV-1371 sitting behind me with RTV on it right now), and they liked to used a pretty big series resistor in them in the power supply and a series regulator. It MUST be something like that. The flyback of course could do this--but the 90-on sets did NOT change the fly's by that much---if in any significant way. However...MANY of them were then "cold" with a switching power supply.

. I think this is more of a stunt to scare people into getting rid of their old TV's.


I FULLY agree... scare the masses into getting a new, crappy flat-panel set.

I guess sony is scared that these sets actually last awhile. lol.

If I remember right, I have changed a number of convergence blocks in that era set(s). The block cracks and can arc to the point of burning its plastic housing.
It was mounted on the side of the CRT shield.

I cant rememberr seeing a sony sety go up in flames? Anyone?

I picked up a KV1473RWP at a thrift shop a couple years ago. It appears to mid 80's design. Dont know where it came from, but it says on the front " TRINITRON AUTOVOLTAGE" It definitely was made for a foreign market.

I worked on tons of 20/25XBR's when i worked for Sony. never saw any lawsuits or units exploding into flames

I cant rememberr seeing a sony sety go up in flames? Anyone?

yeah anyone??? not me and i worked on em

They said due to the age deterioration of this certain part, it might cause a fire. If Sony will ever say what this part is, people who are good with working on TV's should be able to just change the part out for a new one unless it's a special part.

If I remember right, I have changed a number of convergence blocks in that era set(s). The block cracks and can arc to the point of burning its plastic housing.
It was mounted on the side of the CRT shield. I know my '84 sony Trinitron has a slight convergence problem in the lower left hand corner of the picture. It might need a new convergence block?

it was called an HVR block. to adjust convergence. it caused intermittent shut down. ususally the crack was on the bottom. thye were money makers

we used strip magnets for corner correction.

Other than being PX-sold models, this list includes most of the Sony sets I have ever owned (at least three I can see), or wanted to own.

If someone wanted to try to determine the bad part(s), I notice the KV-20XBR and KV-25XBR are both on the list, and the KX-1901 is there but the KX-2501 (and the KX-1901A/KX-2501A) are not. Also, none of the early 26" sets are on the list. The 27VX1 on the list is probably really a 25" set as sold in other countries where they could get away with counting the CRT dimension as the "screen size" still.
