Question about RCA HD52W59 HDTV Projection Television
To fix my HDTV solder joints where should I start looking, is there a certain board to look at or a connection you know about?
If you look at the board you will see what I am talking about. A correct solder connection will look shiny a cold solder connection will be dull and or contain cracks in it. As willtab said this may be a loose connection in one of the ribbon cables so check that too. What you are trying to find is a connection that is loose be it connectorized or soldered. Just remember to work with the test unplugged and only restore power after you have finished soldering and finding loose connections.
I hope this helps,

Is your tv having problems. why do you need to resolder? this set can have bad connections on flyback. this is the big black thing with the red wire coming out. there is been reports of bad connections. on the flat ribbion cable connectors. i have had no problems with these in the shop. the only othe place that ever gave me trouble was the horizontal output tansistor. WARNING. this set can and does hold voltages 340 even with the set unpluged so be careful

Tips for a great answer:
This is typical with many sets when it goes old as there is a high possibility that the components over a period of heating and cooling , tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs.
Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points. Please remove the SMPS and check as it can have poor solder joints. Look for bloated capacitor in the circuit.If seen replace and check.
