Question about Sony KP-61XBR48 61" Rear Projection Television

Popping; sparking of Red Projector to metal frame

Bought this Sony Projection new, but started to crack and pop a few weeks ago. Removed the back and found the Red Projector Unit is arching to the mounting rails from the projector power cable; could this be a bad windings? If so is there a fix or does the entire Project need to be replaced? How much and where can I order one.

Thanks,

Sounds like the red CRT has an internal short. Sometimes happens that the picture tubes develop an internal short and cause arcing. I world CAREFULLY disconnect all of the wires to the CRT and see if the arcing goes away. VERY IMPORTANT!!! there is a high voltage wire attached to each pictur tube, usually a red wire that goes to the side of the tube. You can get a shock even if the TV is unplugged, as the tube will hold a charge for years after the power is disconnected. If you don't feel comfortable doing this, DON"T since the shock is powerful enough to stop your heart.

    Yes you need to replace the RED CRT but there is more to consider. The arcing may have damaged additional componenst, so there is that cost to consider. A CRT (if available, and some no longer are) will likely run between $150-$200. Second, the CRT which does most of the work generating the brightness is the Green CRT, so if the picture is dim you may be looking at replacing another one (or two) CRT's in the near future. Bottom Line: In my opinion, investing in repairs for this set is risky, but the choice is yours

60in Sony KDS-60A2020 LCD rear projection picture goes on and off


yes replace the lamp, sony units have certain specs that the lamp must meet to operate correctly. If the Lamp you purchased is made by LTI, these lamps do not last long as they are poorly manufactured. Look at the bulb and see who is the maker if its says LTI then replace with a Phillips brand that meets spec's for sony.

Loud popping noise and spark coming from red projector


I would guess you have a High Voltage Leak at the Anode Lead Cap where it Mounts to the CRT. This is not a area to mess with You are better off calling a professional to fix it. It may be a little difficult to confirm if it is a intermittent problem.
Hope this helps,

Sony grand wega kf-50we610 red lamp light blinking


The red light means that the prjection bulb needs to be replaced. They ony last about two years depending on hours of use. The low popping sounds as well as fan noise is normal for the Sony projection TV. You can Google the owners manual by entering the brand,model etc. and ask for the owner's manual. I had to go to several sites but eventually found it.

Popping, snapping sound


Hello fulby2001,

Have the CRTs checked for grid to cathode shorts. The CRTs do this (pop and crack) when they have Grid Cathode shorts. I would advise having a qualified TV technician do this for you.

Thank you,

I hop this helps

Panasonic PT-53WX54 What is that popping noise?


A loud popping noise, like a sharp "snap!", is usually caused by high voltage arcing. Somewhere in the high voltage system an insulator may be cracked or loose, such as the plastic around the flyback transformer or one of the rubber cups on a picture tube. When the high voltage arcs, it momentarily drops and the picture could go out for a split second. High voltage is dangerous in projection sets so allow a qualified tech to service it for you.

Flashing color in and out with popping sound


This sounds like the solder joints have cracked on the AFT can inside the tuner, a common Sony problem. Removing the tuner, opening it up and resoldering the grounds and small transformers inside should clear it up.
