Question about Sony KV-36XBR400 36" TV

Open Question

Sony 40 XBR tube cable bleeds through to inputs

I have a 7 year old 40 inch trinitron tube tv (300+ pounder). It has developed a problem in the last year where the cable input bleeds through to any other input I have selected. It is the video only, not the audio. So when we try to watch a dvd or play a video game, the cable video comes through. If I unplug the coax cable, the snow bleeds through. Any help would be appreciated. Thank you.

My experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Another option is to wholesale replace the main board by sending it to Module Exchange at 972-298-1212, or PTS Electronics 800-844-7871 ptscorp.com.
Be careful on buying a new one though. Often times, these new technology ones are much worse. Always Google the model number of the set you intend to buy and add the word 'repair' or 'complaint' to see if it is one of the many models that are customer service nightmares being produced by even the most reputable companies today.
Hope ya fix it!

SOURCE: Sony 36 Wega XBR Flat Screen - sudden death.

This could be a scan amplifier failure, and there is a loss of high voltage to the CRT. Part of the power supply may have also failed. In these sets, if the CRT emission goes low in emission, or the CRT goes defective, the bias supply to the CRT will go in to protect.

An experienced TV service tech can troubleshoot the set and give you an estimate for service. Considering the age of the set, the cost of service may not be worth it.

Sony Trinitron TV now taking around 5 minutes for picture to appear (sound comes on instantly) Is it worth repair or should I cut losses and replace set?


How old is the TV?
Sony Trinitron sounds like it may be from the 1980's?
Some TV engineers can use a piece of equipment to do a "tube boost" but this is sometimes risky and can completely ruin the tube, but it's a risk you would have to take.
If the TV is over 15 years old, and has been used regularly, (like 4 hours every day or more) it seems likely that the tube has reached the end of life.
TV cathode ray tubes are like light bulbs...they do not last forever!

Is the sony trinitron 23 inch tv hd ready


You will need a model number before anyone can even do any research.
In general, there were never many CRT (picture tube) TVs made with the required ATSC tuner and if your set is 5+ years old, it isn't compatible with digital reception.

Green screen and distorted picture sound is good but no picture


It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Intermitant color bursts of red, green, purple


Kevin,

for the color problem,most likely you do have problem with loose contact of components from C-board ( small board connected at the back of CRT "picture tube" which drives every color and size of the screen)if you have knowledge with soldering electronic component parts, resolder this board and also check main board for possible loose contact.

cheers,
mark

Tube going out? Picture goes on/off/on/off/on/off til I go nuts!


If it does this on all inputs (cable, and dvd player) then yes you have a bad tube. If however you have cable and have a cable box it could be the box causing your problem, same with satellite, if you have satellite it could be the box causing your problem. The cable/satalite thing is just kinda a long shot. You most likely have a bad tube, just trying to give you some hope! let me know!

Sony Trinitron experiences


The screen control inside the set may be on the highvoltage transformer or on the crt socket; either way if you can turn it up just a little clockwise and the picture comes up but doesn't look good you are likely to have a bad tube. Or try tapping lightly on the glass neck and watch the picture as you tap. If it reacts to the tap you have a bad tube. but the turning the screen control is the best test. Turn it the other way the picture goes off immediately. bad tube: too costly if it is available.

36 inch sony wega trinitron


I had the same issue earlier this week. 4 year old sony trinitron wega 32 in. I was told by Sony to call technician to repair and have called tech....could be anywhere from $200-$300 repair. I did research the blinks (google "sony blinking codes" to find out what each means) Ours was 6-7 blinks which meant power surge to tv. I advised to Sony that i saw many of the same issues with many of the newer tv's and suggested a recall issue--they denied and where no help.
I will buy a new tv now--definitly not a Sony.
