Question about Sony BRAVIA KDL52XBR2 Television

Horizontal Bars Across the Screen

I am currently experiencing a major issue with my screen in that after a very short time of the TV being turned on, the appearance of 6 evenly sized transparent horizontal bars appear. The TV was purchased in June 2007 and this problem was inherent from the onset. The TV was repaired under warranty and the technician replaced an entire board of some type. The fix was very short term as the lines appeared only after a few months of usage. The TV is no longer under warranty. Is anyone familiar with this issue? Any recommendations on how this can be fixed inexpensively? If this board would need to be replaced again, any idea the fees associated with this repair? Any insight would be greatly appreciated.

    Thanks for your quick response.

    Yes, the bars do show up in the tv's on screen menu, as well as with any input i.e dvd, etc.

    Unfortunately the TV is no longer under warranty, as I did not purchase extended protection. Yes, I am kicking myself in the **** now.

    The TV was "repaired" in 2007, while still under warranty. The tech came and replaced a board of some type, but the problem restarted shortly after being repaired. At that point the TV was out of warranty.

    I'm not sure who to contact at Sony about this.

    It is an absolute shame that such a nice TV purchased in 2007 may have to cost me at least $2K if I need to replace the panel.

    Thanks again for your help.

The problem sounds like hum bars that is the term when ac power is leaking on to your set from the power supply in simple terms .
televisions have a switch mode power supply and the front stage of this is the AC filter one or two large capacitors that block the ac from your set these are set across the + and --_ terminals of the Bridge rectifier the device that converts the AC into DC .. this is not a fault that should be re-ocuring so often especialy with this age of set , unfortunate that this was only repaired so recent but a new board may not realy be needed here just a few components I suggest you get a free estimate done on your set , warranty work and insurance work is always loaded , but private work has to be competative give it a try you may be pleasently surprised

Call Sony they our a reasonable company and keep very good records of repair. One of the questions that should be asked is, do the bars show up in the tv's on screen menu? That would tell me where the problem is.

Horizontal bars across top 1/3 of screen

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Projection TV no picture flashing horiz arcs across top of screen sound okay

You will need convergence work to this unit. Not cheap.(Not recommended for DIY unless already experienced in this type work). Might contact a local servicer experienced with Toshiba & see if they can give you a quote over the phone. Be sure you are sitting.
This is probably a good time to consider entering the 21st century & look at LCD or LED flat screens.

Distorted Picture

Problem is likely main board (processes all signals) or even the power supply board is possible.

Considering brand parts may be hard or impossible to find.

Have power but no sound or picture

Do you have high voltage? Check by turning up one of the screen controls to see if you have retrace lines.(pinstripe diagonal lines across the screen) If present turn the screen control back down until the lines just disappear. Check diodes 6003, 6012, 6025, and resistor 3669. If you don`t get a retrace line by turning up the one of the screen controls, check for missing voltages or shorted components in the horizontal output and power supply circuits. Note: Philips TV`s can be tricky even for experienced technicians. Good luck
