Re: Horizontal hour glass picture

The convergence Ics need replaced. In Hitachi, resistors and sometimes a coil needs replaced as well. The convergence/deflection PCB is available, but, the cost of that board is higher than having a servicer come to your home and repair the unit to component level. If you are not familar with this circuit, then call a servicer. Have them replace both ICs not just one. Make sure they are repairing to component level and not replacing the board. Hope this helps.

Your vertical amp is failing and you will have to get it replaced. If your TV is under warranty, i suggest contacting the shop or manufacturer and get it fixed/replaced.

If not, then you will need to contact a qualified TV repairman to replace the vertical amp for you, as i wouldn't recommend opening the TV set to try a DIY..

Hope that helps. Should you have any further queries, pleas post back, and I will try to assist you as best I can..

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays....

Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

43fdx01b arc at top of screen

Usually this means convergence ic's have to be replaced and possibly a few resistors on small convergence board. Sometimes it requires digital alignment after new parts are soldered in. This repair can cost 175.00-375.00.
