Please describe cold soldering Thank You

trace the cable from the bulb going to the circuits/pins,check the cold solder,re-solder it,look for other associated circuit visually,re-solder and re-try and observe, Thank you

My suggestion is to buy a universal remote, which comes with instructions to program your remote to your tv, and you should be able to fix your problem

Good luck........

From what you describe it could very well be a cold solder joint, this can be a tough find as you need to know where to look on the solder side of the board. It also could be with the wiring going to the switch. Try moving the switch when it is cold to see if it will come on..... here is my email so we can keep working on this and I can answer questions....

I disagree with the diagnosis. I think you problem is with the evaporator fan(Freezer/refrigerator)ciculating fan, this problem is very hard to diagnose because the fan still spins, but not fast enough to circulate chilled air thru the freezer and refrigerator. This problem I have just described is true unless the evaporator coil is not getting cold.if the evaporator coil is not getting cold then I agree with the tech. The answer is no as long as you can silver solder the splice.

OK disassemble the monitor and visually check for bad components or cold solder here is a couple of examples.cold solder bad capacitor

Hi and welcome to FixYa,

Your described problem is as you suspected, the green is missing. This is a common failure and is technically an easy/quick repair. Almost always, the culprit would be a cold solder or a faulty color drive transistor/IC. They would be located on the small squarish PCB (printed circuit board) at the very rear of the tube. Of course, worst case scenario would be a faulty CRT (picture tube), but that would be least likely.

Corrective measure would then be initially re-soldering above describe solder joints and/or replacing faulty transistor/IC.

Good luck and thank you for using FixYa.

Well as you have described the failure must be in a cold solder . After 30 minutes the components heat and if there is a cold solder then the mistake is about to show. I think it is a cold solder somewhere arround color whell or an dlp chip. The first one is easy to find and repair. For the second one I sugest you take it to someone who has a bga soldering machine.
You can try to do it on your own with the backing owen but I would not sugest you to do so.

I have had this problem myself for a while now. If I turn it off and on rapidly, it sometimes works after a short to long while. It tends to be accompanied by a buzzing or popping sound, like electricity arcing.
In researching, I have seen that it's likely a loose ground connection, should be fairly easy to solve... I hope.

Currently looking to see if there's a way I can get into it and do it myself.

Hello 4fiddy,

You have actually diagnosed your own problem, Let me explain; the line "I can slap the left side of the tv and picture will almost always come back on" This indicate some form of poor connection (cold solder joint). If you have a soldering iron, solder (circuit type not pipe type), and a multimeter. Use the soldering iron and solder to redo the cold solder joints , and then test it (the connection) with the multimeter.

I hope this helps

Thank you,

What you have described there is a classic example of the jungle IC failure. Ic301 Sony p/n 8-752-101-04. A pic with no color, and lines or grainy texture in the picture. Not a project you want to tackle if you don't have the proper soldering equipment or skills. And not a costly one at a good repair shop.. Only real hurdle is getting that heavy monster into the shop. To answer your question, yes what you described there is raster. Even the salt & pepper looking screen with no real decernable image is described as raster. In fact any image generated on the CRT is raster. And yes, these sets are prone to solder joint problems, usually ring cracking in circuits that generate the most heat.
