Will not stay on


It sounds like it could be your power supply board. You can get one from tristatemodule or shopjimmy. I personally use tristate its always cheaper and Ive had good luck with them but shopjimmy is pretty good too.

Tv made sizzle pop sound and went out


All depending on the models, but i have seen and work on may units with this problem, there are a few large capacitors on the power supply that are sometimes doubly secured with glue, that in turn becomes conductive and causes faults like this. check all the large capacitors for any low or nil readings and with a fine point probe, carefully remove the glue on the and around the caos, and elsewhere if you see any. Good Luck.

Volume up then pic gone


Good Day;

The TV's front panel may be bad, manual buttons. TEMPT FIX; remove speaker, cloth covered, cover, disconnect cables. TV will work but only with remote.

Good Luck!

You've got a bad solder connection,or broken foil line,s on the pcb (printed circuit board1.gif).Narrow it down by pressing in different places,or use plastic or rubber tip.If not,then you got a shorted load on this fuse and diode.do you have a schematic,whats at the end's of this circuit.D represents a <Diode> not a transistor.

Sounds like you have a jammed / shorted out button on the control panel... Try un-plugging the tv, and then unplug the "button panel" on the front of the tv...see if you can turn the tv on with the remote. Sometimes if one of the buttons gets shorted, it will "lock" the processor from doing ANYTHING else, as it thinks you are holding down the defective button. If this works, simply have the defective switch or control panel replaced, or just leave it unplugged and use the remote only! Hope this helps!

#1 When I turn on the TV the power button comes on then blinks 6 times then goes off for a few seconds then repeats the cycle. I have sound over my surround system during this time but no picture.
#2 My sound would crackle and pop every once and a while until now it does nothing. I have to watch it with the surround sound on.

Tv power button flashing no picture or sound


Short in powersupply check secondary fuse and all other fuses too. Were there a color problem before this/ Because most of these set have convergence problems. The amps May need to be changed and resistors around them.
