I do wish i had more but one thing that will cause a problem like this is spraying air freshener or spray cleaners where the spray can get inside the back of the TV. It will also cause it to pop. Hope its this easy to fix for you, good luck. spray the cleaning rag then wipe TV clean.

There are several possibilities. This model is based on CRT (picture tube) technology, and has a high voltage circuit. This circuit consists of three heavy wires, one from the side of each picture tube (red, green and blue) going to a single connection block. There is another heavy wire from this to the high voltage transformer on one of the circuit boards. First, unplug the set, and wait 20 minutes to make sure everything is cool and residual high voltage charge has drained away. Check the wires at the connection block to make sure they are not loose. There is usually some sort of retainer clip to lock the wires in place, make sure these are not broken or unlatched (sometimes they get brittle with heat and aging). Frequently these are covered with a thick layer of dust held on by electrostatic attraction; gently vacuum this off. If all looks good, plug in the set, and wait until it's dark outside. Turn on the set with the room lights off, and look at the high voltage parts. If you see a blue corona glow or sparking, that part has an insulation breakdown problem or a bad connection. It is normal to see an orange glow at the bottom of each picture tube, and you would also see the three colors of the picture coming out of the tops of the picture tube. WARNING: do not touch the interior of the set while it is on, especially not in the dark. Another probable cause is a cracked solder connection on the power/deflection board (the one with the high voltage transformer on it). If the flickering is one color rather than white or a momentary darkening, the problem is in one picture tube circuit (yellow -> blue dropout; ->cyan -> red dropout; magenta -> green dropout). The picture tube circuit includes not only the high voltage (second anode) section, but also the picture tube drive connection on the base of the tube all the way back to the video processor and switching circuits.

Have you taken the back off to see what is visible to you ? it could be a high voltage transformer or bad connections on the bottom of the SMPS deflection board being the board on the left looking in to the back of set. or a you should be able to see something burnt or a smell of the area some times helps to locate what you don't notice . but most likely the problem in on that circuit board .

Use the focus button.

have you checked in your audio menu on the set to make sure the balance is not turned to one side . the next thing to check would be your input signal if your using av cables or HDMI port . if your using av cables try switching the red and white cable around and see if you have corrected your problem . if not then it starts to look as if its a TV problem you could ohm out the speakers there usually pretty tough but its not impossible to have one that failed . if the speakers check out ok then its going to be on the main board in the set and would require further trouble shooting to determine if the audio output iC has failed or where the problem is located on the board from a coupling cap to iC or associated components . but id check at the signal going in first and work my way back to isolate the problem .

Good Morning if you remove the signal either being HDMI or Av Cables from the source are the bars still there ? if they are id suspect a signal board problem . if there not try unplugging your signal source for 5 min's and then do a restart if problem still exists then contact your service provider for further assistance .

The DVI cable was the early HDMI cable . all later sets have the HDMI port . when you had it hooked to a DVI source did you select that port with the remote ? if it did not function the port may be damaged . as to picture it should give you a HD quality picture that your cable box is broadcasting .

My sony did the same thing and worked fine after replacing the bulb. A pop sounds followed by a squeal is what I heard during and after the bulb blowing out. I hope this helps. And the red light flashed similarly.

you could have a bad flyback usually they will make a sort of a hiss as there is a short internal and even the after market replacement flybacks can be new and defective .. or loss of horizontal drive . also the two chemical ribbons that jumper over from the signal board to the smps /deflection board the white ribbon connectors can cause problems also if you have the black one's there probably alright . or a shorted crt could send it into a shutdown . there are a few things to check and it appears your on the right track you have changed the caps on the deflection pwr board . let me know how it goes please

Yes it has a stand by light and it is red . once the power on is started it checks the rest of the command lines from micro and starts the initialization process once all are satisfied it un mutes the picture . however it appears your fighting a one problem and possibly compounding the problems now .

FX transmitter If you need further help, I’m available over the phone at https://www.6ya.com/expert/richard_b59056c0c62ecb00

is the time and date correct ? if not that should be the problem then

I would say approx. 75 lbs.

strange question, but in this country possetion is 9 tenths of the law, unless you have a court order against you regarding the kids then the law expects you to come to an agreement between yourselves, so they don't have to live with her if they don't want to

hope this helps

Go into the menu and select picture settings and then advanced picture settings. I'm not sure on that model that you can manually change the aspect ratio from zoom to 16:9 or 4:3 ect... But select Auto Format and the TV will pre-select the correct format for viewing..... Any questions just let me know. Bill

Hello there are caps on the SMPS module usually associated with that the tops will be bulged up . id look at the values and check a local electronics part supplier or a local Tv repairman for these caps . Shop Jimmy should have them also on line . or Matt Electronics sells these cap's

So Far You've Done Very Good, The Horiz Output Is Located Very Near Or On The Flyblack Panel, It 's Usually A Rectangular Transistor Mounted To A Very Large Silver Like Heat Sink ..It Does Sound Like It's Shorted, But If Not,Check The Focus Divider Or Hv Tripler..

Your Set Is In HV Shutdown,Probrably Caused By A Shorted Flyback Transformer & Horiz Output Transistor,With That Model Rca, These Items Are All On One Separate Module Or Board,Which Can Be Purchased Seperately..
