Question about Primax Electronics HT2778P TV

2 Answers

Hourglass Picture Turned the TV on in the AM and the picture appeared with an hourglass shape where the vertical center of the picture is in about 1 1/2 inches on each side. I checked the menu structure but there does not appear to be an adjustment for this effect. Thank You

    ALSO...

    Because we live so far out in the Colorado Mountains I opted to "play" with the settings and to make matters much worse, I did something I know that I shouldn't have and that was to get into the service menu structure and fiddle with the settings to try to correct the problem. I ended up modifying the wrong setting whereby the picture immediately went to black and upon restarting all I now have is a blue screen with thin white horizontal and vertical stripes fluttering through it. Now, in addition to my original question / problem, I have to ask..is there a way to reset the tv's service menu back to the default settings. I have no problems getting into the guts of the beast so to speak if that is necessary although I really don't have any testing equipment to speak of.

    Thanks again.

You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..

This is one of the ways to restore the factory settings



Good luck......

It has an hourglass shape when first turned on but


Your TV set has trouble in its "pincushion correction" circuitry, which corrects distortion so the picture is straight on the screen. Unfortunately, it's not possible to pin the trouble down to a specific part without having the set for troubleshooting. Since the trouble clears up after the set's on for a time, it's probably due to a faulty capacitor or intermittent solder connections. Because of the troubleshooting skills and tools needed, you should let a professional service shop handle the repair. This kind of problem is relatively inexpensive to repair (at least parts-wise; I've been out of the repair business for a while now, and have no idea what kind of labor prices shops are charging) and would not cost nearly as much as a replacement TV.

Vertical hold will adjust the frequency (refresh) which would remedy it if the picture was rolling. I had to open up my TV (not recommended unless you know what you're doing) and adjust a "pot" which will adjust your screen's hourglass problem. I hope this helps.

Vertical hold


If the picture is in an hourglass shape this has nothing to do with vertical hold. Besides, on all these sets, the hold and parameters are all uPC controled through a firmware routine that is burned in to an EPROM.

It is obvious that there is a failed component somewhere because of the hour glass shape. The area of failure is most likely in the pin amp section. If the hourglass is from the sides, it would be horizontal pin. If it is top and bottom, the fault is in the vertical pin section.

A common cause is from a capacitor that has failed in the mentioned area. Sometimes it can be an IC or other type of component in the pin amp area, but not as often as failed capacitors.

You can take the set in to service the fault. I don't think you can fix this yourself unless you are trained in TV service and have the experience and setup to troubleshoot for the bad parts, and do this type of service.

replace the convergence ICs STK392-120 you will need both of them also check the 6.8 ohm resistors right next to the ICs as often 1 or 2 of them burn open. You should be able to notice the discoloration in the center of the resistors.
