Question about Samsung PCN5425R 54" Rear Projection Television

2 Answers

Samsung PCL5415RBX TV is four years old. I want to see if I can fix the problem before having to call a repair man that is going to charge me $400+ that maybe I can fix myself. We were out of town for a week, when we got home, kids turned on TV to see a Blue Line that made an inverted crest across the screen. Anybody out there who can help me or lead me in the right direction?

If you have nothing more to offer than this poor excuse for tech support, then you could have not wasted our time by not posting such a stupid comment.

One of your convergence IC's has burned out and needs to be replaced. The Samsung projection sets typically use two STK392-040 IC's, the large black IC's mounted on a large heat sink. If you have never replaced a convergence IC or realigned convergence circuits, allow a qualified tech to handle it for you.

Dear Moorthi,

The problem is created by a small computer located in a top of refrigerator has been broken by any reason. The part is sold at $60-70 but a repair technician usually charge it around $180-200 to rip you off. It happens every 4-5 years. Jenn Air designed its location in a deep and hidden part of top fridge and even skilled consumers can't reach there. Normal repair man charges to fix the problem including labor (1-2 hours, honestly) sums up to $300-400.

The repair cost of $400 is almost big enough to go for a new fridge for most of rich people, unlike me.

I called the 1-800 number for Samsung and got the name of a repair man in Renton, WA. I will speak with him about the potential cost and if it is worth fixing or just let it continue to decline. I do not need your services and do not want to spend $9 to find out where the repair man was.

Thank you for your time.

Blue haze on hitachi 51" tv

I finally emailed Hitachi about the blue haze and since my televison is only 16 months old they agreed to pay for the part (they didn't say what part) and I will have to pay the service charge. The repairman is coming out on 2 Apr 08. I will post results after that.

No picture or sound. Red light comes on then goes off.

I had the same problem with my LTP227W and it is also about 4 years old. Took it in to be fixed and they found it was two capacitors in the power supply. Parts for this TV are not available anymore but they were able to repair the power supply. The TV works fine now. Hopefully I can get another four years out of this. Repair cost was $150.
