Re: Hitachi 27GX01B

Check c458; (100/16) c454; (220/35) c453; (470/35); c451 (2.2/50) all are electrolytic capacitors located near IC 451 (la7845) If you have an ESR meter it would help out greatly to identify the weak cap or caps.

Might not need a schematic. Check the diodes and fuses in the power.

Need some body to help me, could you send me copy off schematic drawing Sony Trinitron Colour TV model : KV-PG21P40. I nedd to check the defective power oscillation.

These are not available for free anywhere that I am aware of. That being said, what is the problem you are having with the set? Perhaps we can assist with some diagnostic suggestions or possible solutions based upon the symptoms you describe.

Looking for schematic of Hitachi 43FDX01B TV- 18 pin transistor

The parts that are missing are likely to be the convergence ICs. These are STK392-110 and should be available online from any electonics parts supplier. Expect a cost of around $25 each.

The symptoms you describe are actually 2 different issues. The easiest way to address this is to attack the vertical problem then if the other still exists, we will address that one. I should be able to provide you with details, but I will need the model number. Please update this with the model number and further details and instructions will follow.

Hitachi 27GX01B pump-up Capacitor, vertical output

I have the same problem with a Phillips Model: 32PT5441/37
ISo far all I can find on this TV is the pump-up capacitor for the vertical output circuit may be bad but I can't find very much information on this model.
I do high end PC system builds and PC repair but have no expertise in TV repair so any help or a solution to my problem would be appreciated...

It might test ok resistance wise but might break down under the load of the television in operation. Then again it depends on how badly it was burned.

Picture problem

Sounds like you are in the begining stages of vertical foldover. This is a problem where the vertical driver waveform is distorted due to a component failure causing the beam to not be driven all the way to the top of the screen. Usually there is enough overscan that you would not necessarily notice the picture being smaller than the crt. When this happens the horizontal scan lines, which have not decreased, are all displayed on top each other or as the condition worsens they invert. This causes the symptoms that you described. The solution I use is to replace all the electrolytic capacitors in the vertical drive circuit. There may only be one bad one but finding it will drive you nuts. They only cost dimes so we're not talking much money. Without a schematic you can usually be successful if you replace all the electrolytic caps around the vertical IC. If you are going to tackle this be careful. TVs are dangerous. Remember to unplug the set and discharge the crt High Voltage anode. Good luck.
