Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts.

Tda 9370


Check the video output RGB out terminals of the TDA9370. Check the voltages. If can, check signal waveform. You have't specified nothing about the audio status. If you wish to get the schematic of TVs, using TDA9370, check the site linked here. Never confirm that the IC is OK. Check the serial data & serial clock. Replace the main system control memory IC, too. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by type in the model name to your set in its search box, or view it in Mosaic /Timeslide option.

My Panasonic TC-21Z88RBN doesn’t displays the total picture vertically ,when the picture is display it like not in the center of the screen sum of it is disappear in the bottom


Hello

Your TVs vertical output section has the fault. You just open your TV after disconnecting it from the AC mains wall socket, and locate the vertical output section. This section uses an Ic marked as part [IC 401] on the board and its number is LA7840. Just look for any loose soderings around its components legs, and the solderings at the IC legs, which has 7 of them. The IC stated above will be screwed onto a heatsink to radiate heat out of it when it works.
If all soldering point are fine, come towards the IC legs and measure the voltages at each leg. The voltages must be
pin 1= Ground
pin 2= 12.6
pin 3= 24.7
pin 4= 4.4
pin 5= 4.4
pin 6= 24v [vcc]
pin 7= 1.8
All voltages stated above are DC voltages with respect to ground. If any of this voltage is missing, find out the reason for that. If all of them are noted abnormal, IC may be defective, and replace it.
[vcc] stands for main input voltage to the IC.
If you need any more assistance, feel free to contact me through Fixya. Ok.

I have a Tedelex Ec Rp 4389 Rear Projection with a convergence problem i replaced ic(stk392-560)with(stk392-570) and it is still the same i noticed that pin 10 of the ic only gets 4.5v is that normal


Pin 10 should be at the positive convergence power voltage. The ICs run on a plus and minus voltage from a power supply. Usually +/- 15V to +/- 30V. (don't know this brand.) (not sure if -570 is replacement for -560; could be.) I'd look through main power supply for these 2 voltages. Ohm to pin 10, etc. Check PS fuses there.

Over Current Protection
Pin 1 of IC951 is also the Over Current Protect input.
The internal FET.s ground return is at pin 2 of
the IC. The voltage drop across R955 and R956
indicates the FET.s current, and is coupled through
R953 to pin 1 of the IC. The Over Current Protect
circuit is activated if the voltage at pin 1 of the IC
exceeds 1.35 volts.
Stabilization and rough regulation are provided by
feedback from pin 3 of T951 to pin 1 of the IC. Fine
regulation feedback is from a secondary supply,
through the Photo Coupler, PC951, to pin 1 of IC951.
Its possible that Diode D953 is leaky allowing the voltage to rise on pin 1 of the IC
