SOURCE: Stopped working

I had a similar problem with a jvc 8040. when I replaced the fuse it became very obvious that the b1560 output on the center channel was blown (smoke and sparks, always a dead giveaway). I haven't fixed the center channel yet but simply unplugged the center channel board and removed it from the unit. Now everything works fine except of course the center channel. Pre outs still operate just fine so a slave amp could be used for center channel power, or you could just go and buy a marantz amp; I did and then I realized that I was lucky that the old jvc quit.

good day.
Have you tried first resoldering the terminals in the circuitry?
Also, try to check for the ABL supply near the flyback. Watch out for the small voltage zener diodes.


response is highly appreciated.

Good day; TRY THESE SOLUTIONS: 1. CHECK IC7A00 PIN 53 FOR LOW LOGIC (0 VOLTS), IF HIGH (3.3 VDC) CHECK FOR SHORTED D9A31 PART # 264P045050 AND OPEN R9A33 220 OHM 1/4 WATT ON THE POWER PCB. This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 2. SELF DIAGNOSIS ERROR INDICATES SHORT PROTECT. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB. I hope this more helpful, big IRISH.

Those are the two 5amp pico fuses that go out when the convergenec Ics go out on a mitsubishi. You can get the ICs and pico fuses at the following link. If youre not sure which ICs you need leave them a email with your model nuber.Heres the link

reset the c.breaker or replace fuse in the main panel service from your home 2) test the power cord 3) test the switch 4) see if the fuse or c.breaker inside is tripper or replace fuse and try again.

if just only clicking sound that was mean the cause either the regulator in the power supply is bad or the horizontal output transistor get damaged.

The red light on my Memorex MLTD2622 does not shine and the tv doesn't even come on anymore how do I fix it


Aside from checking you have power to it and the fuse inside connected directly to the cord is good:

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

Soniq tv manuals


I have fixed 2 soniq tvs that were stuck in standby ie would not turn on via the power switch or remote.
One of them would turn on briefly and then turn off again while the other just refused to even try to turn on.
I thought it was a problem with either the power board or the main board but it was not.
The control board was detecting a problem and was shutting down power board.

The fault with both of them was that the LVDS cable that connects the main board to the T-Con board had poor contacts with the sockets it is plugged into.
Solution was to CAREFULLY unplug the cable at both sockets..don't pull it by the cable or you may disconnect a wire within the cable... and give the pins on the sockets a little spray of electrical contact cleaner then refit the cable securely...make sure it is pushed fully into the sockets.

Hi, Can anyone recognise or diagnose this problem we are having with our Samsung LA32A450 LCD TV? It wont power up, no power on lights. Switch on side of TV wont turn on. Remote wont power it...


hi g_coopster,
Samsung LA32A450 LCD TV wont power up or no power on lights that indicated that no power line.
First of all, check the power line, cable AC cord is it installed properly, change ac cord if necessary. If you experience with electrical tool such as Volt meter, try it to measure the ac voltage from power line.
Or open your rear cover of unit, there are 2 board with difference color brown PCB (IP Board) and Greend PCB (main board). Check fuse on power board, if broken that may cause your problem. Change with the same type as labeled on it. But becareful, if after you change and try plug the power line in than broken again, thats mean power board have sort circuit.
My suggestions, try steps above and if it file, change power PCB block. You can buy it on Samsung cervice center.
Good luck.

I purchased a JVC LT52X579 March 30/09. The TV would phase out by itself and then restart by itself. Some times it would remain on and could be cut off only by unplugging it from my sudge protection...


Hi,
Please unplug TV from wall socket for couple of minutes, replug back in and turn ON.
If still does not power up, try it in another wall socket.
Also check standby/ power light flashing or its solid at TV.
If standby light is flashing or its not lit then TV got power supply problem and requires qualified TV tech. I hope TV is still under warranty so ask for warranty cover to store.
Thanks.

NO POWER AT POWER SUPPLY BOARD EVEN AFTER REPLACING FUSE.


If the mains cord has only 2 pin plug, you can plug it the other way to see if the mains cord has an open circuit at one of the wires. It is not uncommon to find open circuited mains cord for a large appliance like a TV. The degaussing circuit causes a surge in current consumption when you switch on the TV from cold.

Your fuse will be on the main board just after the power cord inlet. Maybe in a small black box that the top opens on.

Solution steps:

1. Make sure that the cable is not plugged into the mains receptacle.

2. Open up the unit

3. Inspect the board. Look out for a glass fuse rated about 3A/220V near one corner of the board. It is close to the mechanical ON/OFF switch on the TV. The cable normally plugs into a socket made up of two vertical pins an inch or less from the fuse. Sometimes these are marked with a squiggle (~) or two (~~) to signify that the mains power goes there.

4. If the cable terminator (end of the cable opposite the mains plug) was cleanly pulled out, then well and good. In that case simply plug it back in. If not (i.e. the cable is damaged, then you may have to remove the terminator and solder the cable directly to the board.

5. To pre-empt any further "pullings", make a knot on the cable inside the TV where the cable comes out so that there is some resistance to the pull.

6. Close the unit and enjoy.
