I have a Hitachi Ultra Vison 57S700 2004 model, the TV has had a slight high piched whine for a couple of weeks and today the screen went green then black and the sound was gone. When it is turned on the...


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.

We have a Panasonic PT-50LC13, the buld died and the unit would no longer light up. We replaced the bulb as noted and the unit still won't light. Do we need to reset something so the unit recognizes a new...


hi I just read that this tv needs a few minutes to warm up i am going to .try it. iam having same problem. i had a tv tech install a bulb and it worked .
but i had a dispute with the tech about the cost of the fix and he took out his bulb and all though i purchased a new housing with bulb in it so that i didn,t have to touch the bulb, when i put it in i got nothing but green to flashing red to yellow. so if my bulb is good and the tech didn't
do something malicous than something has to be reset so that the tv will work because not even the sound of the tv worked.

if you get the ansewr to this please email to kjohnson838@aol.com

Toshiba Picture bouncing... becoming horizontal line


This sounds like a loose connection in the vertical circuit . The vertical IC would be the main suspect . These run somewhat warm and can the solder joints to expand and contract . Now what can also happen if you keep running it this way is the IC can become stressed out and finallly give out . Which will basicly give you one thin line side to side or some TV's when this part fails it will shut the tv down . Most shops depending if you can take it to them or if they have to make service the price will vary . Call around to a few local TV repair shops and get a rough estimate over the phone to what it might cost you . I would hope at best for a service it would not cost over $250.00 . Now if you can use a soldering iron you can save alot by soldering the loose connection yourself . Some experience would be required as some cabling straps would need to be loosened and plugs undone . Good luck and let me know how it turns out ( Team Tech )

Mitsubishi 52725 caps issue


all 47uf, all 220 uf, all 100uf, probably most if not all of the 10uf, and 4.7 uf. it is a pain. they are all surface mount caps and very close to feed thru's. I repair these for a living and have specialized de-soldering equipment just for these. since you have it apart why not check out www.tv-techs.com. it might be easier.

RCA 32 in TV no picture no sound just a beeping noise TV power is on


The beeping sound is most likely the high voltage generator needing replacement. This is a fairly easy job if you have some tech support to discharge the picture tube. You can go to the following link and leave them an email with your model number and your symptom and they will email you back with the part you need and they provide free tech support with instant messageing so you can do the repair yourself. the HV generator takes about a half hr to replace and takes only the basic soldering ability. heres the link.

The site will send you the instructions to replace the ICs and the tech who is assigned to you will help you out with any questions that you need, also if you ask your tech he will more than likely send you the e-book called understanding basic electronics. The tech will walk you through the repair.That site also has the full 2000 plus page complete service manual for the entire series HDTVs that you can order and recieve in an email if you would like to order one that has a lot of info on television stand by and start up power supplies and how to trouble shoot and etc. I am not aware of any online TV repair courses but then again when you hear from your tech ask him as we go the extra distance with our customers. You may end up getting me as your support tech as I am one of the 4 techs that do the online support for them.

Red Lines Bouncing on my Screen


what is the fix? there is high voltage inside a tv if your not careful you could get hurt,
the other problem i have with DIY is they make it worse then what it had to be so i have to charge them double of what would have been a simple repair, or not repairable at all.

Check your screen. I have the same problem with mine. If the screen has a ripple in it, it could give the same effect.

Have mitsu model # ws-65813 wont turn on


You have a common problem in the DM (Digital Module), more specifically the DM power supply. There are four electrolytic caps in that supply 16v/1000uf that are bad and likely buldged from heat stress. Replacing these caps and the E2P module, a small stand-up board further back on the main DM board should restore normal operation...
You might be lucky enough to have a tech come out and simply replace those caps in-home. It's not a really big job for a qualified tech.
Hope this helps!
