Aveis LCD TV no power

The SMPS does not working.Fuse is OK I can measure 160v in the(C102) 68uf 450v capacitor. The power FET driver IC (L6562) did not have power. RV 1,2,3 (150K resistors) are OK QV 1,2,3, ( transistors) are OK CV 1,2 (capacitors )are OK U2 unrecognizable.How can I go further? Any idea what is this part? Does antibody have circuit diagram of this Switching power supply? Thank you.

SOURCE: Sceptre power supply short circuit

I have the same problem. TV was JUST out of warranty. Sceptre part number is X37SV-Naga and the cost - $285.00 plus $20 shipping. Non-refundable, no returnable.

The TV is of course going to de-solder the board within a year again, so either a good heat sing on both thermistors is in order OR a law suit against Sceptre is in order for putting us a risk of fire.

I just fixed a neighbor's by replacing the 2200MFD capacitor on the power supply board. Thanks for the help, worked great. If you replace it got for a 16V instead of the 10V and hopefully it won't fail that way again.

Just be careful and take notes when you're digging into it. And mark exactly where the card cage is before taking it loose.

SOURCE: No power from switch mode power supply. Input fuse

you could try shop jimmys.com or look closely at your supply to see if you might have puffed up caps these can like devices will have a puffed up yop from venting if you find some try replacing them the values are on the side

How do I fix backlight problem on JVC LT32D-500 TV. I want to know if it is perhaps a common problem with this model and it it is FET or transistor related.


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

I recently bought a 100uf 450v capacitor to replace a 68uf 450v capacitor. Unfortunately there is no power being fed to the TV when plugged in. I was told by a local TV repairman that the uf rating...


The fault to your TV might not due to a defective capacitor. A higher capacitance valued capacitor, won't do nothing wrong. But as the capacitance value increases, the size of the capacitor will too increase. That's all. Check the fuse at the power supply regulator board. If it is found opened, make sure that something wrong with the power supply regulator board. Without rectifying the fault, never replace a fuse, as it will make things worse. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

Teac ct m685 shutting down


Removed and checked the power supply unit and confirmed the capacitors
C905 220uF 420V was measured at 200uF
C926 22uF 160V measured at 21.6 uF
C908 10 uF 100V measured at 10.35 uF
C910 47 uF 63V measured at 45.8 uF
Resoldered all of the joints on this PCB to ensure good connections.
On the Main PCB checked capacitors
C401 220uF 35V measured 214 uF
C417 100uF 160V measured 100 uF
C411 3300uF 35V measured 3090 uF
D204 was still a diode
C430 4.7nF 1600V measured 4.5 nF
C406 4700uF 25V measured 4460 uF
Reassembled and confirmed worked OK

These checks / repairs did fix this fault and the television is running well.

Tv won't stay on it shuts off as soon as I turn it on and now there is a blinking light on the front and it's blinking 7 times


Most Sony's usually always have bad regulator ics. Depending on your model, could be a mcz3001 or str ic or mxoa ic. Check for 160v across the main capacitor for 160v to see if your power supply is working. Do not use chassis ground. Use the ground on the cap.

Tv wont turn on (wont stay turned on)


pls. check power coad is likage or luse canaction in plugh
if ok then problum is inside of tv so pls. cheked in pcb.....
1st : SMPS output voltage and 5v /12v/ 24v /135v dc filter capaciter cheked and replace 470/16v /1000/35v / 220/450v if any capaciter likage or sort * first cheked dyode.
2nd : EHT output line capasiter or dyode checked 4.7/250v /100/160v
and line coil or 1ohm register cheked
3rd : DT (driver transfermor ) and with cancting spear dry.
note: pls descanect tv with DVR and cheked tv set is turn on atlist 10min. minimum with any ather product (DVD , GAME BOX ,CABEL CANACTION) if is ok. then problum in DVB setup box .

Tv d'nt work and det power


Just check the B+ of your Tv use a voltmeter and measure the voltage. find the capacitor 160V that is the B+ filter cap.the reading must be around 115vdc.
If no voltage but fuse ok, check the 400v cap. the voltage should be around 380vdc.
