Had a power surge into the house- the tv was not on a surge protector and i am wondering if the tv is blown out- or is there a fuse possibly that blows at a power surge?


hello kath... if the tv won't come on now the power surge fried internal fuse and possibly more. The least expensive way to get this repair is to physically take the tv to the repair shop. If they have to make house calls, the cost goes up significantly. Joe

Code 34 error repair shop wants to charge me $700


It just takes time. An issue like this is one that is known by the manufacturer however it takes time for the repair man to get into your tv and they are paid hourly which is where they make the big bucks. You can do it yourself just fine however you can also put your tv in the grave forever. As long as your ok with buying a new LCD if this does end up dead you should be fine. Always make sure your willing to except the risk, don't forget the insides of projection televisions can store electricity as well.

My tv will not turn on the power light comes on


After the power surge , the TV went on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur after power surge on a rear projection are a blown capacitor on power board, a component on ballast board has blown, or a fault on Digital board had occurred.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Hitachi 60UX58B Comes on then goes back off.....


Yes, i just answered a post to another problem simular to this, it is the POWER SUPPLY, it was blown either from an electric surge, caused by storms or ground faults, or it was shorted. you need to get a new one, have a professional install it for you.

Power button flashes 3 times but not turn on i here a sound in the back of the tv but tv will not come on was wondering if there are any easy checks or what might be a common problem for this and HOW DO I...


If you take off the back cover, cp 150 is located on the left circuit board. There are 3 or 4 C-shaped metal heat sinks in the board, and capacitor cp-150 is located inside the furthest one. Once you find cp 150 check the top of it to see if it is still flat, as opposed to puffed up. If it is puffed up I am almost certain this is you problem.

My tv would flash green 3 times and turn off for 45 seconds. It was taking up to 20 minutes to finally turn it on, so I bought a pack of 5 capacitors off of ebay to replace capacitor cp 150, which is just a (2200uF,16V) capacitor. I replaced it 10 minutes ago, and the tv turned right on. Fix Ya!

TV will not power up


LoL!!! I don't know why but all RCA's have Flyback Transformer problems! I have one to here is the part number 259296 if you look around you can buy it for about 15.00 if you know how to solder you can do it your self and save big time! Hey I'm doing it! I don't see paying $500.00 to fix it you could buy a new one. And they are just ripping people off because the parts aren't really that high to fix the flashing light problem. And the part is never on back order so your getting screwed they are probably wanting you to finally say just throw it away. And than they'll fix it for $15.00 and sell it for $600.00 Anyways for the people that are having the same problem go here to buy the Flyback Transformer for the D52W20 http://www.electronix.com/catalog/advanced_search_result.php?ELECTRONIX_CATALOG_SESSID=c5d90cbb7ae2d4c1449ea48542eef46a&keywords=259296&x=4&y=14

Also here is another website if you have access to junk TV's and want to know what other RCA Flyback Transformer will work. The price on this site is higher for there's though

TV Turns off


Mondern day television sets have to user serviceable parts inside them as they are all solid state and you will not ben able to look at a set and see something wrong. These sets you need specialized test equipment to troubleshoot relace and repair parts inside them. Your set suffered what alot of solid state electronics these days . A power surge will usually blow out the power supply section of a set and who knows what else. If your not a tech a TV set is not a place to be experimenting with anything .. best thing to do is call a tech to trouble shoot and give tyou an estimate. Now if you mailed in the Registration to the surge protector, and the tech writes down that this was all caused by a surge, then you shouldnt have any problems collecting what you laid out for a repair. The surge protector company,if the repair cost alot ,will contact the manufacturer to see how much the parts listed ncost and if these parts could go bad when a power surge to stop peeps from padding there bills. Make sure you get a complete itimized bill not just repaired power supply on a bill cause you wont get paid. Also make sure you call an authorized repair place for the manufacturer of your set. as its not 100% necassary, but much more legiter in the eyes of the power strip company. Good Luck
