Question about Flat Panel Televisions

1 Answer

I am having two problems with my Sony PFM 42v1 TV monitor.  The first problem is that it is having that double-image that other people have posted about.  That is, the top half of the screen is basically ok, but the bottom is a ghosty double image of the top.  Second, the TV is now turning itself off for a split second, then turning back on. Any ideas on what I can do to fix these problems?  And are the solutions so expensive that I should just get a new TV? Thanks. -Daniel

    Thanks for the insights, mistersony. Any idea how much this might cost if I go to a certified repair shop to fix it? I am trying to decide if it is worth fixing or if I should just put that money to a new one (I would prefer to repair, but only if it makes sense economically).

I suspect you have a SUS board failure, but it may be worse than that. What it sounds like is the SUS board that drives the bottom half of the panel has failed, but the problem may not end there. The only way to know is to replace the defective SUS board (Y SUS) and possibly the Y DB (driver board). The real possiblilty exists that you may have a bad plasma panel as well, but the only way to tell is to replace the Y SUS and Y DB boards first and see what happens and what you have. The repairs are DEFINITELY NOT something an average consumer should attempt, as there are adjustments that must be done after replacing the boards and the very real possiblity of ELECTRICAL SHOCK exists. I wish I had better news for you; please don't rate me poorly for giving you the correct information.

    Because of the age of the unit and the fact that some money will have to be invested BEFORE you know if the panel is bad, I would cut bait and start looking at a new TV. As a technician that has worked on many brands and currently repairs Sonys on a daily basis, a few recommendations; you can take them or leave them. If you want the best, buy Sony. Best customer support, best built in diagnostics, just overall the best, and I'm not just saying that because I work on them, I'm saying that because it is FACT. If you want to look at other brands, next choices would be Sharp, JVC and Samsung, in that order. Second (and I know you wish you had known this ealier) NO PLASMA. Just plain nasty to work on, failures are often catastrophic and expensive, most susceptible to burn in. When you're looking at LCD, you may notice motion lag as compared to your old plasma, but avoid the temptation to spend the extra for the frame doubling circuitry, I haven't been impresssed by the results vs. the cost PLUS they are still limited by the response time of the LCD and you can't change the laws of physics by adding a board. Last, buy an extended warranty, but NOT FROM THE DEALER. My gripes with dealer extended warranties are they misrepresent the warranty ("it's a 3 year extended warranty" yes, except the first year runs concurrent with the manufacturer and if I have a problem in the first year, you'll tell me to call the manufacturer anyway) and some of the warranties will use substandard or remanufactured parts to save money. With a Sony, you can go to their website anytime during the first year and buy an extended warranty, you get original sony parts and a sony qualified tech (not Fred's TV) working on your unit. Why buy extended? The biggest reason is the conversion of all electronics manufacturers over to lead-free solder, which has turned out to be JOB SECURITY for me. Lead free solder is brittle, will crack under mechanical and thermal stress and grows microscopic tin "whiskers" which can detach and cause shorts in circuitry. You gave me a great rating, so I owe you. If you have any other questions ask and I'll try top answer them. Thanks for the rating, it is appreciated!

Sony pfm 42b1 negative picture


Hi,

I have a Sony PFM-42v1 and it does the same thing, look in your tv menu for picture inversion, usually under screen saver. What it actually does is reduce the chance of screen burnin. By reversing the image it sort of resets the hot areas, brightest colours and the cooler areas being dark colours, switches them around ( negative ). This cools the hot spots and heats up the cold spots.

There should be a option to turn it off, mine and I guess yours as a default is ON, mine has the ON, timer and OFF options.

Hope this helps, please let me know if you need more info.

Sony Tv PFM-42 V1 doesn't show any picture or tv menu


This is a common problem with plasma tvs You did not mention whether you could generate any sound like through your dvd player or something like that. Whether you have audio or not makes a difference on which board may be causing you the problem. Just because it does not have a picture for tv viewing does not mean it won't produce some type of sound through your av1 input. Try it and I'll try to be more specific.

Sony PFM-42V1 bottom half of the screen is a blurry ghost image of top


The Sony Plasma designe not to repair at component level your problem I believe in YSUS PCB you can adjust a few variables resistors on this PCB make sure to mark on the spot before turn you can alway go back to original point, set your plasma on normal channel turn the variable resistor slowly and observe the picture any spot will effect the picture if you can not adjust you need to replace a new PCB
Let me know how you go
