SOURCE: Sony TV keeps shutting down ever 5 mins

Could be loose connections on the board where the solder is expanding as it heats up causing a loose connection or something in the power supply or horizontal is over heating and your tv is going into shutdown protection . Good luck

SOURCE: My 50 inch hitachi projection tv keeps powering up and down.

First it is not an emergency.
No Legitimate repair company should be that busy.
Call Hitachi and get an AUTHORIZED Hitachi dealer to service your TV.
Your problem is beyond self help/
Unplug the TV until it is repaired properly or you will do more damage and have a much larger repair bill.

SOURCE: where is the air filter on this tv ?? it keeps

the filter is located internal to the unit and you must dissemble your unit to clean or replace it this is not as a user serviceable item on some units, contact Panasonic via there web sight and request information from there tech services for further info.

Hello, i will list the criteria required to service TV and projector TV`s first and foremost you require a good understanding of how TV`s work and the ability of reading schematic diagrams, then you require a knowledge of how printed circuit boards are patterned so you can navigate around them to locate possible trouble spots.
then you require
1 multie meter of good quality
1 oscilloscope 20 MHz or better
1 shop service manual pertinent to your type and model of unit you wish to repair
this is a minimum requirement of test equipment you can have

you also kneed a location or locations to obtain the replacement parts you may require to complete the service task.
Now if you have all the above criteria in place then you have some hope to service your unit

a flashing red indicator on your TV usually refers to an internal circuit failure, most modern TV`s have circuits incorporated in the circuit design to protect good working components not involved in the fault from further damage so the set will not power up and an indicator light will start flashing, trouble spots can be anything like power supply under voltage, over voltage over current, no vertical deflection, excessive high voltage, XRAY, convergence failure,, EXT EXT,EXT,
Warning rear projection televisions can harbor in excess of 30,000 ,yes that is thousand Volts

There are and never will be user serviceable components inside LOL

Now if you are ready and require further assistance you may contact me and i will step you through the diagnostic procedures Good luck

Panasonic pt52lcx15 TV. Recently, after approximately 5 min. The TV turns off. Is this some sort of power supply issue? Or, something else?


Try this.

Unplug the tv. take off the back panel. vacuum or blow out the dust with a can of compressed air (@ $3 at Staples). A lot of the projection tvs had a thermal sensor which would turn the tv off if it got to hot.

That is also a good time to clean the lenses. Be careful not to move them out of alignment. My tv worked like new after I did those things.

TV turns itself off, then on automaticlly


The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

Tv switches off after 5 mins


There might be three or more reasons for this:
1) The sleep timer may be on causing the TV to turn off after a preset time.
2) If sleep timer is on and no signal from the remote is received for a preset time (Samsung: 15 minutes) the tv will turn itself off.
3) The TV may have been turned on automaticaly with "On Timer". If so, and no signal is received for a preset time (Samsung: 3 hours) the tv will turn itself off.
4) A fan is not working or a vent is blocked causing the TV to overheat and turn off.
For 1) thru 3), go to the "setup" menu and make sure "sleep timer" and "On Timer" are turned off.

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!
