Question about Sony FD Trinitron WEGA KV-36HS420 36" TV

2 Answers

KV-34HS420-Sony Tv Recently my TV seems to have developed a black "frame" around the picture. All around the edges of the picture there is a section of the screen that is only black. The picture does not seem to be distorted in any way, it just seems as if the picture no longer encompasses the whole screen. The black section is approxiamatley an an inch on each side. Any ideas?

Are you sure you don't have the zoom changed on the TV? Check what picutre selection you are using.

Well based on ur info, ur tv has a prolem in power supply section, particularly regulation circuit. the regulator of the circuit seems to be mulfunctioning thats why insufficient voltage is coming out from B+ which in turn goes to high voltage circuits thats why the produced picture is insufficient. if this is very technical to u, have it check with a qualified technician.

How many times do this light flashes. Count it. These blinks are fault indications. From these number of blinks, you can get an idea about the faulty circuit section inside. It will make troubleshooting more narrower. If you wish to get more details about the blinking codes to Sony TVs, check this link. Pull up older posts there.

Our Trinitron KV-36XBR400 powers up then no picture

How old is this tv?More than 5 years old.Not worth it to repair CRT tv at this prices.Tries unplug,replug an hour later,might help,see if reset itself.U can buy a pretty good 32" LCD tv at $400 or less these day.It not heavy as the CRT tv,it alot easier to move the tv around the house or other locations.

Sony KV-36XBR450 seems to turn on but screen slightly pops white around edges but immediately goes all black and will not show a picture.

According to the symptom the problem seems that the high voltage cap is loose and not plugged properly. For your convenience see the below pic and reset it. The number 11 is the target component in pic. Hope this will solve your problem.


Note: This component has a high voltage, please don't forget safety measures.
Thanks for using fixya.

check the heater as your tv is ON, there must be a yellow light at the rear of the CRT tube. If the heater is ok then check the IC jungle side. resoldering the leads sometimes will solve. If not refer to your local Tech.
