Plasma tv out of focus after repair

I got a Philips 42PF9630A 42" HD around one year ago. After 8 months, the TV began to turn off by itself, so I got it repaired. Now I got the TV back, the problem is disappeared but the image on the TV is no longer the same: it is a little blurred and out of focus. It's not so crispy and crystal clear like before. Any idea? I asked to the technician but seems to don't understand what I am talking about! Is it possible that by replacing some component inside some setting or knob has been altered?

Any idea is very welcome. Thank you!

it could have over heated you can try to reset it first unplug it for about five minutes and try to turn it on if that dont work the remote might have a set button try holding that down until the red light flashes twice, then turn it on if not then hold the power button down on the set for a good five seconds to see if that resets it. if none of that works you will have to go to panasonic .com for the reset instructions.with the red light blinking the power supply is most likely good you just need to reset i.

This is know as a diffusion issue. Most times this can be corrected with some minor alignment on the pots on the YSUS pwb. Sometimes the YSUS pwb has failed and will need to be replaced.

Ok 7 red blinking led, remove the back cover of the TV. Looking at the power supply in the upper left of power supply. If everything is working fine you will see a solid green led if there is an error, you will see this light blinking also. Right below this led on the power board you will see a list of numbers 1-13 this will give u the problems that this led flashing problems are. More and likely u will have a problem with VSET or VSCAN. Which is connected to the Y-Main and Y-buffers,( the board that is too the left of the power supply if u look on the small print on this board you will see that it reads. 42HDV4 Ymain and the 2 small boards connected to it are Y buffers. To be sure that this board is bad if the TV keeps going into error protection. unplug the power supply and wait for the led to stop flashing. Disconnect the cable that plugs into Y-Main from the Power Supply. It should stay running. If u remove this board and look underneath u should be able to see where this board is getting hot. Easiest fix is to order a replacement. Y-main assembly.

SOURCE: plasma TV with vertical lines

Help! My Plasma by Magnavox is putting black verticle lines on the right side of the screen - comes and goes - and I replaced the entire Direct TV-HD unit - wires, everything - and had TV company repair - and it still came back. The TV repair refuses to take TV back because it does not show up when they come. Although I videotaped it and showed them which has the date and time - they still refused to take it - and tried to get me to sign a paper saying it was working while they were there - which of course I refused to sign - so they left and nastily said they will not be back-find someone else. I still have the lines - and do not know what to do! Can anyone help?

SOURCE: 8 month old Symphonic 20 inch lcd tv turns off itself every 3-5 seconds

these sets that shut down or turn themselves off after a few seconds usally have a bad backlite board in them. look closely at the screen and see if one section looks darker than the rest of the screen (top middle or bottom - top seems most common in my cases). some times if you put the tv on an unused input you can see the variation of light level on the screen, but don't get confussed by looking at the screen from too great of an angle. thanks ......techman 580-243-8025

5 year old plasma that looses half the picture

Hello. I recommend that you forget the repair for two reasons. 1. Pricey. 2. You still have a 5 year old set with no warranty. In the last five years, the tv technology has come so far. The HD is fabulous. The new sets cost less to operate and they are so much better than they were five years ago. Joe

I have a Philips plasma 42 with black lines across the screen

I would first check if there is an available firmware upgrade for your model .Upgrade requires you to download firmware from philips website.Then transfer it to a memory stick .Then use a memory stick reader to plug into tv for firmware upgrade.Other wise the set would probably need repair .Possible a bad SSB board or another issue

Menu screen keeps coming on

I hate to call Philips liars but the logic of the situation speaks for itself. If it was a software fault then your tv would have done this from day one and I bet it just started to do it out of the blue. I think it could be a faulty component on the board where the buttons are located. Hope this helps.
