My wife could hear cracking comming out of the tv,but ignored it untill it got too bad and eventually unplugged it. i pulled the back off and tried it again,the flyback transformer had a hole burned in the casing and was arcing to the top of the transformer,so bieng mr fixit i got some glue and filled the hole,now the arcing has stopped but when i turned it back on the screen has only a single white line across it.i have located a flyback transformer,but now im wondering if a new flyback transformer will fix it ,or if this has damaged something else. i dont know too much about this stuff and would greatly appreciate any help.thanks
I beleive something in the vertical circuit got damaged. Check resisters to see if they are burned and locate the vertical IC has about 8 to 10 pins. It stands up on the board and all the pins connect into the board in a straight line. If you can't do this, take the set in for service. Get the fly back replaced and the vertical section fixed.

For a temp.fix,tries unplug,replug the tv back about an hour later,so the tv power and other boards to reset itself.Tries websites like Shopjimmy.com.Ebay.com to buy a refurbish power supply board for the replacement.
The plugs on this model projector is very delicate, over time the solder around the plug will begin to crack. Until eventually the connection is lost. Another possibility is that the power supply has gone bad. Using another cord would not cause this. I can fix the projector if you'd like. My ebay screenname is gtitubro.
sounds like the main board might have cracked, hope not but its a possibility, we can try a hard reset and see if it fixes the ps3's programing (if its a programing error) when your system is on hold the power button down until you hear 2 beeps (providing this works being you have to turn off the system by unplugging it) Oh have you tried using the power switch in the back? Anyway if u hear the dual beep it signifies that the system has reverted back to the factory settings. Hope this works for you
Sounds like bad solder around the power supply or deflection circuits. take the back cover off and using something non conductive i.e a wooden salad spoon try knocking on some of the heatsinks and around the circuit if it reacts it may help you pinpoint the area of the problem. next you`ll need to pull out the circuit and solder the connections that look weak, they might have a ring like hairline crack around the solder joint. good luck and don`t forget to unplug before working on it.you dont want to end up with curly hairs
ch for bad solder by the vert ic do you hear a hige tack you hand and move it in front of the tv whean it on if it ting your hane you have hige vo to the pix tube unplug the tv and then take off the back. and how plug in tv trun it on tap on the board and see if your video come back on if dose you have bad solder on board.
That flasher is built into the Hazard Light switch... Pulled it out, opened it up. Everything is surface mount devices and 3 little sealed relays. Banged on it with a screwdriver handle and, Voila!It may start to work. Perhaps you can repair the original. Sometimes solder joints go bad - especially when high current is pulled. Check the relay solder joints. Good chance the solder has oxidized (dull gray color) because of the high current pulled by the turn signal lights - or even a visible crack around the relay terminal itself. Solder is not a great conductor, and it heats up and oxidizes because solder is (in effect) a resistor - which resists the flow of current. There is a small voltage drop between the relay terminal and the solder/pad on the circuit board. As the solder heats up, the solder begins to oxidize - and eventually the connection goes bad. Good luck and hope this helps.
The buzzing noise you are hearing is most likely the ballast fire, this is good. You most likely have a bad lamp which is the best case for you. I would recommend pulling the lamp out and looking at it to see if its physically shattered or not.
The instructions for pulling the lamp can be found in your owners manual. If you do not have this anymore just look on the sides or the back of the tv for a small door with a screw or 2 in it. take those screws out and the door should come off, then take the screw(s) out of the lamp and pull it out. if you see glass rolling around inside you will need a new lamp. Let me know and I will help you find a good one at a good price.
if you are not afraid to get in to the back of tv, the chassie has 4 different fans,you can unplug the tv remove all of the screws on the back,and remove the lamp door,there are about 5 plugs on the top of the chassie that plugs in the tv,donot unplug these plugs ,you can pull the chassie out of tv until you run out of wire on the plugs,then plug the tv in,turn the tv on, and you might hear the fan thats bad. If you are not comfortable with this call a repair man,the fans are not that expensive,and are pretty easy to change.i can guide you thru the replacement process if you need my help.
