Question about Toshiba 57HX83 57" Rear Projection HDTV-Ready Television

1 Answer

Switches on then off then on then off...

A few months ago my tv started this one. I switch it on and sometimes it stays on for a minute or so then the screen goes blank, sometimes the screen remains blank from the start. After another minute it shows the channel its tuned to on the screen but no picture and I have to turn it off and on. After two or three times of this it comes on and stays on - the picture (when it arrives) is perfect. Is this a power supply problem and can I fix it myself without blowing up the neighbours' homes as well?

Re: Switches on then off then on then off...

The first thing to try is to see if your set has loose conections,you need to remove the back and tap in diffrent areas of the chassis to see if it reacts,if it does you'll know soemthing is loose and it has to be resoldered,if you are familiar with tv service you will have a place to start checking but if you are not too familiar seek the assistance of a servicer,the repair should not be expensive.Let Us know how it goes or if you need more information.

The lamp has just been replaced and now the tv will only stay on for 30 minutes and then turn itself off. The lamp indicator light is red. We can turn the tv back on and the light goes off. Six months ago...

Did you press the System Reset button with a ball point pin on the front of the set? You might have a ballast going bad if it has never been replaced. But first, the reset button then you may have a thermal switch which is located just above the lamp housing. I test the thermal switches by unhooking (while set is unplugged) one of the wires and then putting an alligator clip jumper between the two wires to see if it last longer than the 30 minutes you mentioned. Lastly, there must not be any dust in and around the fan which can cause overheating. Sounds like you have an overheating problem initially. The thermal switch cuts the set off if there is overheating. And also if the switch is faulty it will cut off the set. Also look in the menu for a temperature setting if this model has a setting such as this.

Have a Mitsubishi TV wd60735 the tv volume just increases to max by itself, sometimes won't turn on, sometimes no remotes will work it and I have to pull the plug to reset it to get it to come on, have it...

Sounds like your tact switches on the front of the TV are shorting out. Unplug the plug for the switches. if the problem goes away then try to clean the switches with rubbing alcohol, if still has problem replace switches.

Tv switches off and on

If lamp is good, Did you reset lamp hours? That should be done. Reset instructions are different for different brand tv's.
If you have reset the lamp hour counter, then test the ballast and the power supply to make sure they are sending out a constant voltage and current reading.

I think it could be a faulty diode on the power supply board. If you can check this for yourself otherwise call out a competant technician. Good luck.

Model RE44SZ21D when I switch TV on it maks a whinning sound like a hard drive not reading properly and switches back into standby. Sometimes it will start, (normally if not tried for sometime) stays on...

hello john.
this is a late suggestion,but if you still have the set & the proplem
in existence.
then i suggest you check with the lamp---situated on the right hand
side ,two screws to undo--once in further two screws--pull back the
casing clean with a dry cotton cloth & with that clean the cooling
fan just adjasent to the case.+ remember to leave the tv on standby mode for 3 minutes before you completely switch it off ,as this helps to cool down the lamp the fan at rear still propels while the tv is in standby mode.--------ASH

I had the same issue. Replaced the lamp and now mine is working. Normally this is a sign that the bulb is out, however - I would say now that either:
1. Your lamp is defective.  2. The balast in your TV is defective. 
I would check out - they can help.

Faulty lamp could be, there is also a little blue switch behind the lamp door that needs to be in the down position.
