SOURCE: No picture...Sound is fine.

There are no tubes, except the picture tube, to replace.. itys a solid state set. your problem is most likly thefiliment circuiut on the crt board, or maybe a verticle problem. I would say with A set of this ventage, will most likly cost to repair more then the sets worth.

ok i'm goin to need more info about your problem. you stated fuses and didn't say the location numbers of the fuses. Also, have you rechecked your fuses to see if they are all still good? 3 fuses sounds like more then one problem. once you tell us your loc#'s of your fuses, we can look into your problems.

hi,doe sthe screen of your TV lights up?during power on?if not then there might be a problem on the inverter board and the backlight lamp of the monitor .The lamp is a cold cathode bulb it requires a high voltage supply from the inverter board in order to light up.just like any other bulb this lamp has a limited life span more or less 2 years of continues lit.The inverter board is a high voltage board the power input of this board is 24volts DC and the output is 200volts AC.The terminal input of this board or connectors must be check because of high voltage corrosion and loose connections always happen that leads to the mal function of the display or screen failure just like what happen to your TV.
Backlight lamp is installed at the top and bottom of the screen you need to open the back cover of your TV to check up the lamp.(make sure to unplug the TV before proceeding)..check first the test point that I mentioned then post back for your findings then will proceed to further trouble shooting...GOOD LUCK!

Good day.

If you already replaced a new inverter board and T-con board and the problem is still there.Try to play the video on the DVD,if the video is OK check the cable connection and try to run auto scan.
If the problem is still there check the input supply of the system board or main board it should have 5vdc and 12vdc,if it is OK replace the system board.

Review this manual page 4-1 abnormal display http://www.scribd.com/doc/36875894/Olevia-232-S12-SM

I hope this solution will be helpful.Thank you for using FixYa.

SOURCE: I have a MATAG DRYER

Hi outback557...

Here are a few things to check:
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or the dryer,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor/thermal fuse one at a time by removing the two wires and taping them together with electrical tape.
If the coil heats up then replace the thermostat/thermistor/thermal fuse as it is faulty.
If you have an ohm meter then you can test the thermostat/thermistor/thermal fuse,
then you do not have to tape the wires together as described above.
To test your thermostat/thermistor/thermal fuse remove the wires from the thermostat/thermistor/thermal fuse and check for continuity, if you DO NOT have continuity then replace the thermostat/thermistor/thermal fuse.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST AS THIS COULD CAUSE A FIRE BECAUSE YOU HAVE REMOVED THE SAFETY.
Check your blower wheel to make sure it is secure to the shaft and not plugged with lint,socks,etc.
If the thermal fuse overheats the dryer will not operate. It's located on the blower housing. It cannot be reset.
You can test it with an Ohm meter or continuity checker, remove both wires from the thermal fuse and put the test probes to each of the ends of the thermal fuse, if no continuity then replace the thermal fuse.
A vent clogged with lint can cause it to overheat.
Right after replacing a dryer element, always run the dryer on 'air fluff' / 'no heat', and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

Signal Problem


Hi,

When the sound is working and the picture is not it indicates the main power supplies are working but the picture supply is not. The picture supply that powers the projection tubes is a high voltage generator and is very expensive to repair. Not even most tv techs now how to troubleshoot them. So, I cannot recommend you repair it yourself unless you are a trained high voltage tech.

The cost of repair - my wild guess - would be around $300. However, the real cost can only be determined by someone who can make an accurate diagnosis - which will require a hands-on approach the problem.

If you have any other problem please ask me..
Goodluck,

My Toshiba model # LCD TV 42AV500U picture went to a black screen, but i still have audio. by doing research it maybe that the backlight board is the problem.


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.
http://electronicshelponline.blogspot.com/
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. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main digital board.

This is an LCD tv . Toshiba 40xv648u .Audio is good screen is dark. was taking longer and longer to come on.


Since the picture died slowly i suspect a capacitor on the powersupply board,if the screen flashes then goes black and sound is ok
could be the inverter board that drives the lamps.

Toshiba 42RV530U I have 3 flashing amber lights and no picture or sound. Any ideas of what the problem could be?


That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

My toshiba model no. 50hp66 is clicking on/off when plugged in but the picture does not come up..is this a common problem and what are somethings i can check to find and fix the problem


Hi,,,,,
first try to check power cord if still good,
if its ok, try to remove cover at the back of your LCD, find the power supply board check if it has some capacitor bloated.
you can do some repair from that problem,
by replacing those capacitor. be sure to replace same value and put to right polarity, because capacitor has a positive and negative size.
if you know how to solder or use a soldering iron,
try to watch this for some tips on repair.

if this wont work maybe your TV has other problem,
thanks .... be generous for giving some rate.......

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.
