Unfortunately your problem seems to do with a faulty part inside,it may be an inverter or something more simple.But you cannot tell unless you physically open it and check.You will need more hands on expertise for this.

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, something simple like a blown fuse inside the TV. The most common board to go bad is the Backlight Inverter Board. It what supplies power to the screen. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

I have a 46 inch Samsung plasma HP R4252 picture went black


Probably the power supply that drives the video has gone bad. Samsung recommends the TV go to a service center. If you have some skill and are willing to try, open up the back of the TV, remove the shielding and look at the boards to identify any obvious damage. Leaking or bulging capacitors, soot, scorch marks are the obvious. (Other parts can have bad solder or tiny cracks that are hard to spot.)

http://www.shopjimmy.com/catalogsearch/result/index/q/HP-R4252 has reclaimed parts for this TV. These are parts from TVs that were damaged in shipping and were only run during quality control tests. They list several power supplies for the model so check what part number is actually installed (there is usually a label on the board).

I hope this helps.

Loud sound coming out back of television...like a motor when turn tv on


it could be a fan going bad or it could be an electronic problem I would advise to have some one look into it before it damaged the tv permanently.

TV SHUT OFF WHILE WATCHING. UNPLUG AND THEN PLUGED BACK IN. RED LIGHT CAME ON IN FRONT FOR A SECOND AND WENT BACK OFF. TV WILL NOT COME ON.


power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.

Verticle lines on screen


This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
