You may have problem in the logic board, it uses surface monted components no much chance for DIY repair.

The cases these days are hard to open, they use plastic finger hooks types, they go in easy but real hard to remove without damageing them.
Use thin flat blade to crack open at the bottom edge so the scratches will not be so noticeable, and work your way around, look out for cables attached to the front bezel also.

A veteran IBM. Open the case and try to locate a sub-brightness knob and carefully "add" more power. And the end is not so far, I am afraid.

this is hardware problem - replace flyback transformer & big transisitor fixed near flyback (replacing these two parts is compulsory ) - also check all small size transistors ( 6 to 10 transistors will be there on main board - see picture ) - below shown picture is only to get an idea as how these parts looks like & roughly where they are situated on main board ... that means this picture is not that of your monitor's main board - in your monitor there will slight difference & also that bigsize transistor's number will be different ....... for more details about flyback transformer check this link http://www.fixya.com/support/t10123898-panasonic_ct_36hl43g_tv_just_turned

There is a short within the HT section and this can be possible with the failure of the flyback transformer or the driver transisitor.
So if you are equipped please open the back panel and check for shorting on the driver, also when powered this can heat up which confirms that the flyback is shorted.
replace with the same type.

This is a fault solution which can be checked and corrected by you assuming that there is no component failure. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.

The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.

Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

Check for tips to look into the SMPS unit with some of my tips:

capacitor (either ceramic or electrolitic) that connect to vertical ic (TDA8173 or TDA 9302) is short or open. Check all capacitor in vertical range. tq
