We have a Samsung PS50Q91HDX Plasma Tv which is not quite 3yrs old. Ever since we have had it, it turns itself on & off at random but this is not the main problem. Last night we were watching a show...


This is weird. I also have a plasma 50" model PS5Q91HDX and on the 5/02/11 the screen went blank when my friends daughter was watching a Wiggles DVD. The image kept coming back, flashing a scene or two before going black again. But the sound is perfect.

I wonder what is going on? Is anyone else having trouble with their 3-4 year old Samsung 50" TVs???

The tv is at least 17 years old.The blinking red light blinks 5 times ,then the tv picture goes off . The voice is still on


Five blinks is the error code for an AKB (auto kine bias) error. What this means is that the set isn't able to balance the three color guns (red, green and blue) of the picture tube properly, and it's blanking out the screen.

To get the proper colors, the signals for the three colors need to be balanced, and Sony sets have circuitry to do this automatically. Other brands don't, and when they go out of balance you see a picture that starts to show tinting or colors that are off. As the picture tube ages, it gets harder to adjust the balance until finally the AKB circuit can't anymore, and poof, the picture goes away. With a 17-year-old tube, it's not surprising.

There isn't anything that can be done to fix the picture tube, it would need to be replaced. But the cost of the tube and the work required to get it set up after installation makes it completely uneconomical to repair this TV. A new picture tube is nearly $200. Then special tools are required to set the tube up (a process called convergence), so you'd need to find someone to put it in, and possibly pay to have the old one disposed of. A new 32-inch LCD set is around $350 now. Treat yourself to a new one.

The colors aren't matching up I have green semi


Yoy have convergence issue with tv,try the magic focus/touch focus or manual adjustment in the menu under convergence, if can't be adjusted then your convergence ckt is the problem,you will need a tv tech to repair it.

I have an rca L42WD22YX5 that just went to a blank screen yesterday. The screen keeps reading unusable signal. It is only 14 months old.


i had this happen last year, now my tv is messed up again. when we had the problem with the unusable signal, the tv repair shop told us it was the main motherboard that caused it. ended up paying $250.00 to have it fixed. Now, our tv is broke again, this morning turned it on, got the green light, then just started flashing red, hasnt worked any at all today, reset it and everything. My suggestion, if you can afford to buy a new tv, do it, because I called the repair shop again this morning about the new problem, they said after the 1 year warrentt from rca runs out all they do is tear up. My tv isnt even 4 years old, bought it at the end of 2007, now its tore up twice, going to purchase a samsung in the morning from brandsmart. Good Luck!

The t.v.just went blank while watching it.


Power boards are like time bombs. When it's time is up, it's up. Since it is 3 yrs old, I would buy a new tv. Most TV parts only last 3-5 years anyways. It did a good job.

Our screen went black no picture only sound


Try a hard restart, which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. If this does not bring the picture back, then you should consider buying a new TV. The costs of a repair ( labor and parts) might exceed the cost of a new TV. Your 10 year old TV has served you well, and has exceeded the average life expectancy of 5 years. May it rest in peace in TV heaven.

I have a 6 year old Samsung PCJ522R 52" TV.


It sounds like at least one of 3 "IHVT",s popped. in short, a "IHVT" is a high voltage transformer. It will have to be replaced along with any other parts that were damaged in the process.
They do produce a strong odor when they pop!!

It is repairable but at a price. there is a good chance that parts will have to be ordered.

you might consider buying a new LCD HDTV instead of fixing this one.
