Question about Zenith B36A24Z 36" TV

COMPLETELY DEAD NO SOUND NO PICTURE I also noticed a part was loose - looks like a silver nickel (round) with two wires soldered to it. I believe this part is THX3415 and has the following numbers stamped on the disc: 63-11119 778909

    Thanks for the help.

    Now, any ideas on why the set is completely dead?

    same problem and found the thermistor unhooked and soldered it back on but it still has HV shutdown. Any help would be appreciated I have checked the common capacitors C3210 and 3211 and found them to be OK. Any help is great.

Hey !!! I solved my own problem. After I soldered up the thermistor I still had the same problem so I checked all the known parts around the startup circuit including the power supply relay and relay driver. All found to be good so I then attached a scope and signal generator and applied a horiz signal to the base of the Horiz output...voila!! I got high voltage so I tracked the horiz siganl thru the circuit and found a coil to be bad along with 2 electroletic Capacitors. The Zenith part number for the coil is 20-4073-01 and its part # on the board is LX3262. The caps are 4.7 Mfd @ 50 VDC located at CX3261 and 10 Mfd @ 350 VDC located at CX3205. I hope this will help someone else.

That would have to be looked at and trouble shooted on the bench by a professional. So many things could cause that symptom.

That's called a thermistor. It's used in the degaussing circuit of the TV. If it's loose from under the board then it won't hurt to resolder it back on.

No picture but with sound

There are three things you should try. If you can safely pull the back cover out safely, do so. First thing to look for,is the suction cup attached to the picture tube securely? Be sure that it is. Make sure the TV is not plugged in, when you check for a good ground to the Tube (suction Cup). Then plug the TV in and power up. Still no pic? If you feel that this is not the problem, next, pull the board out of the TV. Be sure to discharge the picture tube before you remove the suction cup. Unplug the TV. A wire taped to a flat screwdriver, the other end of the wire connected to the silver braid that surrounds the picture tube. Now slip the screwdriver under the suction cup, you will hear a snap, you have discharged the tube, you may remove the suction cup. And you may pull the board completely out of the TV. Find the vertical IC and resolder the 7 or 9 pins. Do not use excess solder and short the pins together. Each pin must soldered individually and not together. Check for bad solder grounds on the horizontal transformer. This transformer is usually a small square box with five or six pins. When not soldered with a good ground, it will crate the problem you describe. Next, solder the pins on the Flyback Transformer. Resolder any and all power resistors. A power resistor is one of two watts or more. I do not believe your horizontal transistor is bad in this case, you resolder this as well. A bat transistor would hand you a dead TV. Do go over the rest of the board and really look close for any and all bad solder grounds, solder as necessary. Last be sure you have good solder grounds on the back of the small board that connects to the picture tube. I'm sure you will get your picture back, try all of the above and let me know how things go. Thanks for asking and show all hands of support!

No sound

some manner of bad connection there, thing to do is next time it messes up, pull the back and jiggle one at a time, till you find the one thats the key. from there it is a choice of which end is at fault or if its the wire itself. when i say connector it could be the ones that are on that wire, or it could be the corresponding part or its wire connections. dirty genrally is a constant prob. loose is cleaning contact areas, squeezing female parts lightly so they make a good tight fit. if this is a soldered connection, and either end looks a good solder joint, then..its fault of the wire itself, If you go through one at a time, Im sure the fault will present itself to you.

Blue power light is on but tv will not come on olevia 237T11

I know this post was a while ago, but I stumbled upon a solution to my tv just recently. I don't know if this will work for everyone's tv, but I find it hard to believe that this would only fix my tv with the same issue.

I opened up my tv and found that the placement for the connection for the power cord is poorly designed. For one it is very loose. Two, I don't know much about circuit boards but the connector has 5 prongs. Two of which are part of the same piece to both, I think, to anchor it down and ground it (it looks like it's part of the actual ground wire.) and the other three which I assume power the board. Those three are not completely soldered on completely e.g. they have holes in the soldering. The last thing I noticed is the ground wire is crossing the board and touching one of the coils.

As my tv got worse it started making a "short" sound. When I opened it up, I removed the connector and insulated the wire more. Also, I anchored it down tighter using the two prong piece (just made it tighter by pushing it down more and folding the prongs against the board and soldering it). Last, I re-soldered the 3 prongs, completely covering them. Put the tv back together and came back on and no problems.

I hope this help and I hope this makes it around to all the people who have this tv. It"s not a bad tv just a poorly designed board.

One of two things may be happening. 1) a loose connection (cold solder joint) has developed on the board that supplies the horizontal section or loose contacts around the flyback transformer . 2) A short in the line that feeds the horizontal . Without the horizontal section running you will have no High Voltage to light the pix tube or as you said won't raise the hair on your arm . If you take it to a shop tell them your problem. Your estimate would be based on the size of your TV and the parts and labor needed . Asked what there estimate fee is to look at the set if you take it to them . Or if you have soldering iron and some skills take it apart and give it a good look over . Make sure it is unplugged and be cafeful of the red wire that connects to the picture tube. Good luck

GPS signal is weak or no signal


Thanks for using FIXYA!

Careful when opening the case because you'll have to unplug the cable from the main board prior to opening the case completely.

The RF cable could be loose inside. Carefully open the unit as to not potentially cause any further damage. The RF cable will be gray or black, it will be the only cable connected from the main (big) board to the RF (attached to the rear housing.. I believe) board. The connectors on either side of the cable have came loose. A "pad" being lifted results in a repair process that's beyond me, this meaning you can see white as opposed to silver. It may help continuity to re-flow the solder, if everything looks fine (heating up the existing solder and adding fresh solder).

Unplug the cable on both ends and plug back in to make sure the connectors on the circuit board aren't coming loose. If soldering is out of your league then I suggest finding someone that can. Let me know what happens, and careful when opening the case because you'll have to unplug the cable from the main board prior to opening the case completely.

32 inch rca color

If this is a 32 inch TV then it is a standard picture tube set. If the colors have suddenly gone out of whack, and the set has not been dropped or had any large magnets near it recently, it means that the degaussing thermistor has come loose from its legs. This is very common in the RCA regular picture tube sets. If you look in the back of the set you will see a large black coil of wire wrapped around the edges of the picture tube, with 2 white wires going down to a jack on the main PC board. Right next to that jack is the degaussing thermistor, which looks like a small silver disc, like a nickle, with 2 legs loosely soldered to its sides. One or both of those legs are probably loose, and if you are very careful you can solder those legs back onto the thermistor. If you do not have experience soldering small parts, allow a qualified tech to handle it for you.
