    I can't work out how to get the get the back off the TV. I have taken all the screws out but there are two narrow rectangular slots along the top edge at the back of the TV about 5cm from the each outside edge of the TV. Are these some kind of fixing?

    Hi Nate,



    Thanks for your responses. I haven't managed to get the back off but I can now see through the rear panel something that every now and again glows like a burning ember. It's about 5mm long and 0.5 mm wide. Everytime it glows there's a puff of smoke.



    The TV is about 20 years old so maybe it's about time I replaced it. I'll probably look for a used CRT because I'm still not convinced by the picture quality of affordable flat panels.



    Thanks, Jon.

Are you able to visually inspect the circuit boards and looked for burnt solder joints or cracked ones. Im assuming since you hear crackles they might be burnt if so you can attempt to remove the solder in place and resolder the joint also look for any bulging or leaking capacitors.


lemme know so i can further assist you.

    ok then dont turn it on or try and do anything else then the damage would be visible if you opened it up for service it is probably best to call a technician and have it repaired proffessionally.

When I turn on grand WEGA KDF-55xs955 55 in. projection tv it does nothing but make a crackling noise from the left speaker. The screen stays black, I get no picture at all, and it also starts to smell...


Have you checked the lamp? I would start there if you haven't. Take the lamp out and look down in it to see if the filament is cracked or broken. That is definately what it sounds like. I have seen many of these at shop.

Tv all the sudden wont turn on and wires smell like they are burn


What worked last night and last week does not play any role on what works now. The issue here is power supply that you smelling, and that crackling sound backs it up. Now you have choices but there not all in your favor and you got to expect that when it comes to repair as its going to put a dent in the wallet.

Powerboard/deflection unit $250 plus labor..

Plus whatever got burned inside during this whole ordeal. Concider this: Cost of new verses Repair of old. Also a new tv will give you its life plus 3 years warranty to boot, this tv will give you 90 days after its fixed on the part only, after witch other things can go wroung.

I agree with repair only if your willing to pay for it. There are Quality repair places like www.teexp.com click and check if they can come to you if not you need to check you local listings for a tech locally.

diagnosis: power/deflection unit
Prognosis: 90 days parts/? Labor

please be considerate whren leaving positive ratings and feedback today.

Horrible burning smell from lamp


If you ordered it directly from sony then i would be concerned and contact the to have it replaced under warranty. If you did not get it directly from sony I would expect it is a rebuilt lamp or you purchased just the lamp part instead of the whole cartridge and installed it into the carttridge yourself. The lamp is designed to be replaced as a cartridge . The smell is probly a lamp that is burning the wires on the back side of the lamp because it is incorrectly inserted and the wires are touching the glass. Just a couple times i have seen a lamp that will smell slightly as the plastic and insulation heats up for the first time.But it only smells a little for like a day.

RCA D52W19 "crackles" and smells like its burning


Hello pmzone_guard, This problem is quite common in this TV it's due to a capacitor in the power supply being overloaded. The chassis model is a ITC222. The capacitor is located on the deflection board which is part of the power supply and should not be touch by someone that does not have TV Repair Experience, due to the fact that this area of the TV is the most dangerous. I would suggest having a qualified TV repair technician do the repair on this TV. If the problem is just that one capacitor the part will cost about $2.50 at the most, so the charge will be the cost of the part plus the labor involved. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

"pop sound", picture out, burning smell...?


Usually, yes. A bulb that has audibly 'popped' will be apparently bad if you pull it out of the TV (shattered). Other times this is a lamp ballast board.
