Look for the PIP PCB problem.. `jack
Hello Podman6,Does the fault come on and off when you tap the case/cabinet of the TV? If so, then this is a dry joint/cold solder somewhere on the mainboard.If you are are not qualified, do not take the cover off. Look for a "largish" aluminium heatsink, located probably near the middle of the PCB. (It may be on the right hand side.) With the cover off & an image showing on the TV, tap the heatsink with the "handle" of a screwdriver. Search for the most sensitive heatsink. Disconnect the power look closely at the other side of the most sensitive heatsink & you will probably find a "dry jointed" I.C. If your set has an IC.501, look for a small capacitor near this IC./it will be 1 uf/50v or 2.2 uf/50v. You can make out which are faulty, because their caps will be swollen on top. Here's a sample pic (not same model): Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you, or get a qualified technician. Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified technician to do it for you. REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.If you are unsure, PLEASE CALL A QUALIFIED REPAIRMAN.Hope that helps, and thank you for using FixYa!IrishDruid
