Picture goes in and out; must press/hit front bottom of tv to get picture back
I have a Panasonic CT-27G14; recently, the picture periodically goes in and out. In order to get the picture back, I need to either press hard or hit the front bottom of the TV, near where the front video/audio jacks are located. I usually have to hit the tv several times before the picture comes back for good (until I shut it off again). Is there an easy way I can fix this myself. If not, does someone know how much it would cost to get this problem fixed? Thanks...

Tip: The max point reward for answering a question is 15.
It will be good to check the capacitor on the +B voltage that goes to the power section in the main board. A filter capacitor of about 47mF/160 V can be defective.
Next check the capacitor on the HT line to the grid-22mf/250V replace.
If possible loop on capacitors in the horizontal section particulary the IC.
Now the tip I can offer:
If the fault occurs on heating shcek out htis area to confirm and isolate the component.
But finally I understand that when you press any key the picture is good.If so check the memory IC/cmos IC in this section for logic control, it might be having a switching fault, a conflict or the video noise is coming on in default but goes off in the data selection mode. Do a soldering around this section on the IC , capacitor and see if the fault goes off or becomes irregular when this section is heated, if so there is a semiconductor producing this noise error .
So start from the begining so that we have a clean voltage inside.
I hope my advice helps.
firt try with your cellular, put your cellular in camera and put your remote control in front of your cellular and press one botton, if you see a blincking ligth, your control is good and your IR sensor in the tv is bad.
