Re: Vertical Hold adjustment

You can search this database for the service info you seek about your tv here:

Most service manuals with schematics cost about $27.95 for the PDF version of it, otherwise the paper version is about $15.00 more for handling and shipping.

You will need the chassis number of the unit in question in order to search for it. I hope this helps!

Good Luck!

I have an RCA R52WH74. I took the front of the tv off to get to the red, green, and blue projectors. I'm have a hard time getting all three to line up correctly by manually adjusting each one. Anyone have...

The adjustments are all done inside the service menu if the auto convergence defaults have been erased. Manually adjusting them at the CRTs will only mess up the geometry and will never be correct unless each CRT is cenetered properly then do the settings through the service menu and then save the defaults.

Power Supply failure.

You need a professional.
Stop using the TV until it is repaired.
Call the manufacturer to find you nearest authorized service center.

Cant see top 2" of program

Try going to the service mode. I think it goes like this. Press menu, and hold it. Then press volume up and volume down at the same time for 8 seconds. Then you should be able to go to service mode. scroll down till you find the adjustment for vertical size, the top part. If the service mode proceedure I gave you is wrong, You can try asking someone else here if they know how to go into service mode for your particular model.

Picture is cut off on the bottom of my Hitachi 57F500

Verical position is hard to adjust and is in service menu. A service manual will get you there, but you might get lucky with the vertical size adjustment. If you open the front of the TV, the vertical size is adjusted with a knob on the deflection board. Remove the speaker grille and take off the access panel. You will see two knobs, one horizontal and one vertical. Be careful, those red wires have 30,000 volts on then, don't touch anything but those knobs. If its just an adjustment, the v-size knob will fix. Set it so ESPN ticker is just above the bottom of the screen. *Service mode - the manual tells little but entering is done by "press and hold the input button, press the power button, release both after you hear HV come up" .. the v-pos parameter is in there, but this manual doesn't say where or how to adjust, procede at your own risk. If you get into trouble, pull the power so you don't save any settings. I believe you just navigate through the menus to find the parameter and use arrows to adjust. Enter may save. Sorry the service manual I have tells nothing much.

Vertical adjustment

I got your previous post. normally, the adjustments are toward the back following the back side of the main board, if they are not there, then they are sprayed all around the main board itself. things to look for are:


I'm looking for a service manual for your tv 27pt9015d. still not having any joy finding this manual. the problem you are experiencing is technically called "vertical fold over", if there is no adjustments, then it's circuit controlled and will probably need servicing.

Rolling screen

Does the onscreen menu roll too? If so, vertical hold needs to be adjusted. Not sure if on this model if that's in the service menu or a manual adjustment on the motherboard. Keep searching google and see if anyone else has had that issue too. 
Good Luck!

Picture is too tall

After looking at the service manual, there is an adjustment for the vertical size, but it is in the service mans menu, and this is a dangerous place to be if you do not know what you are doing. I do have the two part service manual, and if you want to attempt this, you certainly can, but I highly advise against it, as I have seen peeps mess up a TV set royally this way. It should not cost too much to repair, unless the problem is not simply an adjustment and is a part going bad. Good Luck
