HELLO I NEED A REMOTE CONTROL FOR THIS TV MODEL


There are 2 remotes that work right out of the box for these, the Samsung and the LG if you can find one. Best option of course is the 2 yr old and newer samsung LCD TV remotes.
There are also some Harsper remotes available on Ebay at the time of this writing.

Where can I obtain a schematic diagram for the amilo pro v2055 mainboard please?


You can't. I've never seen schematics offered by any manufacturer for their laptops (or desktops, for that matter), even to warranty service centers. The boards were never intended to be serviced to component level, just replaced as a single part.

When I worked at a shop full-time servicing laptops we had some success at repairing boards with power problems where it was possible to trace out the circuits and identify bad parts. But most of the time all we could do was change the board.

Hello paulaspec,

You have a problem with the three factors, and they are screen voltage, focus voltage, and control (focus 2) voltage. Basically these voltages have to be adjusted since the components in this section have aged some. These controls are usually located in the television on the IHVT (Integrated High Voltage Transformer) or as it is also called the flyback transformer. these controls must be adjusted together, along with the color controls. Here is how the adjustment is done (You will need a schematic diagram, a DC volt meter, and a color bar generator to do these measurments):

 

1) turn color and tint fully counter clockwise until you have a black and white picture.

 

2) connect the color bar generator to the TV (ch 3) and turn it on, you should see bars in various shades of gray

 

3) adjust as best as possible the color and tint controls to obtain the color bars on the screen Red Green Blue.

 

4) measure the voltages on the focus, screen and control grids of the CRT and match them to the schematic digram measurements.

 

5) adjust the focus screen and control grids to match the ones on the schematic diagram

 

6) once this is done then you adjust the color controls once again to obtain the red green and blue bars on the TV screen.

 

This should help if the CRT (picture tube) electron guns are still good and if the flyback transformer voltage supply is working.

 

However if you do not have a background in electronics please take the TV to a shop for repairs.

 

I hope this helps,

Thank you,

Re:philips


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.
