Hello winwithrose,

The popping sound may have been a capacitor. The chance are the capacitor is in the HV section of the TV set and is part of the supply to the Horizontal section of the TV. First if you do not have electronics experience I would suggest you take the TV to a qualified TV repair shop. OK now if you have electronics experience I would say to unplug the TV, open the set up and do a physical inspection of the TV you will be looking for a capacitor that has exploded; if you find one look at the schematic for the TV and find its value. Then do so checks to find out why did the capacitor explode. Most likely the capacitor exploded because of wear and tear, but it always pays to check. Replace the capacitor with one of the same value and then turn the TV on, use your voltmeter to measure the voltage across the capacitor to make sure its the same or close to the value on the schematic.

These are the basics of what to do

I hope this helps

Thank you,

If you do not have menu, problem in power supply, supplying the 130v to the high voltage circuit. Check all pico fuses in power supply.

My Magnavox Projection Tv has the 3D appearance for awhile and now it has no picture at all...only sound. what is wrong with it?


Sounds like your convergence IC's need replaced for starters. Not sure if that is causing your no picture though. More than likely you have some resistors out as well as a fuse or 2 in the convergence line. If you have a meter I would start there.

sounds like the coolant if it appears as halos. If it appears like a 3D picture its the convergence ICs.

General post....
51MP392H/17

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted pictures on, check out page 3

Where I got all my parts that worked:
Suburban Electronics http://www.suburban-elect.com/

Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads



What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux


BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com

No picture


Hello susbudi and Jazz617,

I would suggest do a check on the voltage from the IHVT to the High Voltage multiplier.
This will determine if this is a HV problem or not. If it is not It may be a video delivery problem which would have similar results. In any event both of these tasks I would suggest be preformed by a qualified TV repair technician.

I hope this helps,

Thank You,
