Power on problem


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

turn (only by 2 to 5 degrees ) all the knobs on flyback transformer in clockwise direction & then switch on tv .............you will get picture atleast for 1 or 2 mins ............ this confirms only flyback transformer is defective ........ so it has to be replaced by new one .................otherwise transistor (big in size fixed near flyback with its back clamped or screewed to aluminium metal ) has to be checked ......if that is also fine then complete main board has to be checked ...... but flyback replacement is a must ........in your case iam 100 % sure only flyback is deffective ...........vishnuswamy_26.jpg

We replaced the transformer for our RCA F27650. It was sparking and now it is not, but now the screen won't turn on. It is just black. We hookd all the wires up like they were. we can hear sound, but...


Hello
Along with the flyback transofrmer, its horizontal output transistor also must be replaced. I don't know whether you have replaced it or not. If not, replace it too. It can be located very near to the flyback transformer, a three terminal component, black in colour, usually screwed to a metal heatsink. Then switch on the TV and measure the video output voltage at the video output card pluged directly to the picture tube neck. The collector of the video aoutput transistors must come around 145VDC. If it also is there, advance the screen control on the flyback transformer to get a raster. If that voltage is not there, it means that the flyback transformer is not working, and horizontal oscillator stage should be checked for oscillation, check the lined drive transformer for its primary winding open, Check the entire horizontal oscillator section. The collector point of the line drive transistor, the transistor that drives the line drive transformer, a small transformer soldered diretly to the printed circuit board; should be checked with frequency meter. The frequency at that point should come around 15525HZ approx: OK.

Ur high voltage it dead.The FBT is dead,it the Flyback Transformer.The big black block of plastic with a red wire with a cap plug to ur CRT(Tv tube).The "H" Transistor might be dead also.The "H" transistor is to left side steel side wall cage that surounded the FBT.

I cant figure out how to ge the deflection board


This should be a 400mA brown fuse beside the flyback (gray and black Transformer with 2 thicker wires comming from it.
Once the back cover is removed the deflection board is the board on the left (as your facing the rear of the set) Remove/unplug (deflection board side) all the wires (label or mark them first).This includesBP010,BP011, BP150 etc. The board is held by plastic clips around the perimiter of the board. you have to release the clips while raising the board working from the front to back from the left side tilting the board to the right.There are 2 clips that go through the board- one beside the flyback (right side) and one near the other transformer on the board (left hand side).
