Re: Switch off

It could be due to build up of heat, check for large quantities of dust that may have gathered and make sure nothing is obstructing the ventalation of the unit. It may well be that it will not turn back on until it has cooled. Failing that, it may be a power supply issue and could quite possibly be a failsafe preventing the power supply from blowing and quite possibly damaging the components of the television, if the TV is expensive, I'd advise against trying to turn it on any further and contacting a professional repairman to inspect the components inside to determine what part is at fault. Also, on an off-chance, make sure the TV does not have an automatic sleep timer set, or some sort of set parental control viewing times set. Some Televisions do have these features.

Screen for the menu flashes on constantly while viewing also volume sometimes can't be controlled by remote or tv but other times goes up and down without touching anything

that problem because switch tack are dirty. Open your TV, pull out pcb than replace all switch or clean up them with WD40 or contact cleaner.
good luck.

Tv turns off and on again by itself--safe way to repair at home?


The regulator is not involved in this problem if the regulator is the defect you cant turn on the tv, but the issue is theturns off without warning, and often turns back on again the switch is also a suspect for this problem, you know in this case we do not look for a one bad parts, maybe the Solder is cold solder, or maybe the tact switch, or some bad capacitor or change value resistor. ill re commend you to look for a qualified electronic technician to clearly diagnose for this problem...

Note.. as i read in this complaint the regulator is good and not to replace..

Push the power button and the action button on the tv set until it shuts itself off and this will reset your tv. You cannot use the remote to reset...must use the actual tv buttons on the television set.

HD Video Recorder - CEC connection with HDTV

My first question would be, Is your Panasonic HD recorder CEC compliant? CEC means Consumer Electronics Control. That simply allows for the consumer to have better control over their Home Theater set up through the connection of you HDMI cable from their remote control without programing the remote control for every single device that is connected. If your recorder is CEC compliant the television should have automatically recognize the recorder and control you recorder via remote control (I am assuming that your recorder is an HD Camcorder, since your description was very vague). Once you connect your HD camcorder to your panasonic tv the tv should have turned on switching to the correct input and the same for any other CEC comliant devices. If your Panasonic HD recorder is not CEC compliant the you would have to start viewing your recorder the old fashion way, by using the recorder remote control or if your Toshiba remote is universal punch those codes in so that you can control your devices that way. If that don't work, try a different HDMI input and select the input and make sure your recorder is set to output on you tv. Hope this helps.....before I forget, check out this site to learn more about Consumer Electronics Control (CEC)

No picture

You have an intermittant vertical sweep circuit! It could be the vertical out put IC solder connections on the printed circuit board, or maybe the IC itself has poor connections between the IC and the contact legs that mount the IC, or another componet in the vertical sweep circuit. If you know how to solder and unsolder, work on printed circuit boards, then you shoul have no problem replacing the vertical sweep circuit. Good Luck
