Problem when getting High Voltage on Hitachi 65SWX20B

I bought this TV in January 2003 and it is about 5 years old. One day when I tried to turn the TV on using remote nothing happened. I unplugged from the wall outlet and plugged it back again; the power light comes and gets shut down again. I called technician and when he opened the back of the TV and tapped on all the parts, TV came back again. Within two days same problem occurred. Technician told me that he has to trouble shoot the board and will charge $350 plus parts to remove the Board and take it to his shop. I checked with another shop and the Deflection board and power supply board costs around 200 and 350 each. Is it worth trouble shooting the situation or is this a known problem like changing a IC? If I can by these boards, it might be cheaper to replace the boards ( less labor ). I don't want to spend $800 on this TV. Any help is greatly appreciated.

I was wondering whether its worth changing the boards or to replace parts on the existing board. When TV powers up, I don't have any issue with the convergence. So I am thinking it may be power supply board. Do you think there is any problem with the deflection board. Is this board involved in supplying horizontal ( high voltage ). Do you think its better to change both boards. Any suggestions.

Why should you spend 800$ when the tech told you 350. And yes, do what he said to you. 350 is a good price for what involve this repair. If you want to replace by yourself the 2 boards...remember the eeprom is on the signal board and you have to redo all geometry and convergence adjustments. Even for an experienced tech this is a 3 hours job and you have to be very good.

This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.

Can I store the Hitachi 65swx20b in an unheated inside location. Estimate low of 33 degrees F.

You can do this but I would (thank god it does not get that cold here much in California) COVER IT WITH PACKING QUILTS AND OR CARDBOARD ALL AROUND TO TRY TO PROTECT IT.

AS long as you do not get actual ice or snow on it you should be ok.

Hitachi 51F510 with NO POWER

Something is preventing the power supply from operating:
Possible causes in order of likelihood:
1) Convergence amps failed overloading the supply (See if you can disconnect them)
2) High Voltage circuit has died. (Right on schedule since your TV is 10 years old)
3) One of the CRTs has shorted
4) The power supply itself has died (Is there a lot of dust covering it?)
See if you can isolate the failure by working down the list.
Hope Ya Fix it!

I have a hitachi ultravision 60sx11ka

cory, your losing the high voltage, could be bad solder joints in the horizontal circuit, ie; driver transformer, horizontal output transistor, or the transistor and associated capacitors have finally failed. If you keep trying and it will eventually start then it`s definitely bad solder and that`s a cheap fix from any local tech.
