20 Most Recent Sony Grand WEGA KF50WE610 50" Rear Projection HDTV-Ready Television - Page 9 Questions & Answers

Hi,
6 times red light blink in Sony KF-50WE610 tv indicates problem of missing 17V supply from G1 (power supply) board.
Please check G1 board and replace it, G1 board is located at left side mounted vertically.
Let me know if you have additional question.
Thanks.

Try a new bulb.

This is a protection circuit that prevents the tv from coming on (to stop damage of the components) ....you need to check your voltages off the power supply and make sure they all read well (EX: 24v12v5v etc). Also look for popped capacitors that would make the values lower than need be for the tv to power on properly. The capactiors will fix this issue once they are replaced.


Hope this helps :)

Thats not good...........the pixels are dead. You're gonna need a new television

This is one of Sony's issues they are having with the optical block.
random line pattern, or road-mapping), red bands, and others. They usually become evident after about 4,000-10,000 hours of usage--typically about 2-6 years after purchase, depending on the frequency and conditions of usage. Unfortunately, it is not cost-effective to have the optical block professionally replaced out-of-warranty (~$900-$1,500 total for diagnosis, part, labor, and taxes).

Generally, the 2002-2005 models had 1-year parts/labor express warranties, and the 2006-2007 models added a 2-year warranty on the optical block (still with 1 year on labor). In response to the problems, Sony issued extended warranties to cover replacement of the optical blocks for all of their 2003-2007 models, except the 2005 3LCD models. Similar problems have been reported with 2002 models, but there are very limited numbers of these first-generation models. Some models (WE and XBR950 series) are also susceptible to being warped, melted, cracked, scorched, and or burnt due to excessive heat from the projection lamp, which can cause the TVs to fail to power up and could be a safety issue. This issue is under warranty through March of 2011.

Unfortunately, the extended optical block warranties generally only continue the coverage through about 3-4 total years of ownership (depending on the purchase date), which is far less than the expected, marketed life span of these premium TVs, and many customers experience the failure only after the extended warranty has expired. In addition, the replacement optical blocks, which only have a 90-day warranty, appear to suffer from the same, or similar, latent defects as the originals, so they tend to fail after similar amounts of usage or sooner. In many cases, it has been reported that the replacement optical blocks are bad out-of-the box or within a few weeks to months.
The television image is created by projecting light from a high-intensity mercury vapor arc lamp onto three small (approximately 1" across) liquid crystal panels inside the optical block. There is one panel each for the colors red, green, and blue, and they are combined with a prism and enlarged onto the back of the large viewing screen with a projection lens. Depending on the TV model, the optical block is based on one of two liquid crystal technologies: conventional liquid crystal display (LCD) technology ("3LCD" models) or liquid crystal on silicon (LCoS) technology ("SXRDTM" models). All of the 2002-2006 and some of the 2007 models use the WEGATM video processing engine and are generally known as Grand WEGAs. The remaining 2007 models use the newer BRAVIATM engine and branding.

The discolorations arise due to degradation of parts within the optical block assembly during long-term exposure to heat, light, and/or dust. The high-intensity lamp is attached to the optical block, and it creates a lot of heat. In addition, it creates intense light, much of which is converted to heat inside the optical block as it is filtered. Some of the light-filtering parts, including, in many cases, the liquid crystal panels themselves, utilize organic dyes or other substances that are subject to degradation from heat and light, particularly light in the high-energy blue light path (e.g., UV and deep blue). Also, the optical blocks are not sealed, so dust can accumulate on the internal parts, which can further reduce cooling efficiency, as well as directly cause discolorations.

I am going to pasts some more repair options for this, as you might want to contact your local Sony people and see if they are willing to help on this. If you decide you want to change this out on your own I can give you instructions and advise on the repair as well.

Have you ever tried to clean the air intake filter that sits behind your speaker grill. Have you ever replaced your lamp before either?

Unfortunately it is not. The bulbs of the two models are completely different sizes and shapes. You can buy the correct parts for your television here:

Hi,

Lamp Access door for Sony KF50WE610 is below the screen on the front of the TV. This page shows location of Lamp access door and DIY bulb change instructions for most SONY LCD TVs:

Look at Optical Engine Faults before buying a lamp or bulb. Replacement bulb will not repair these problems.

Hi Don,
This problem is commonly caused by leaky electrolytic capacitor on the power supply section.
This cap affect the regulation of the supply and sometimes needs a little warm up to back from functioning. The symptom will get worst if not isolated the cap. Some leaky cap shows bulged at the top but not all, it is better to check with an ohmmeter. Look also if there is a dry joints in that area.
Hope it may help you.
Have a nice day!

Hi,
The most common cause of this symptom, by far, is the loss of vertical deflection amplifier. It usually requires the replacement of the vertical output transistor or some component associated with it. The cost of repair would run around $150 to $200 depending on the exact parts replacement and the shop that does the work.

i hope this will be help full to you .
goodluck

Hi,
Do you get red light blinking on tv front?
If yes, please count how many times it flashing after three second long pause and let me know to diagnose problem.
Thanks.

sorry but u have bad optical block , the only way to fix this problem is by replacing the optical block

Hi


Thanks for using FixYa. The issue seems to be with the lamp going bad. However, if you have not replaced the lamp with a new one and you know it is absolutely fine then you are right, the issue is with the ballast that has gone bad and should be replaced as it is the power source for the bulb.Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

The convergence is off. If you can't adjust it from the settings then the board itself is off - refurbish it. Here's the kit for it

The ribbon cable is an itegral part of the Red LCD Immager and cannot be replaced.

Hi,
KDS50A2000 is lcd rear projection tv, lamp is light source in this tv and it is not related with color spots/ shades problem in picture. It is problem of light engine that is available in discount-merchant.com for $330 click above link to view light engine image and price info.
Qualified tv tech is required to replace light engine in tv as it is not user level repair.
Hope these info will help you to decide either get tv repaired or buy new tv.
Thanks.

Hi franklin, my name is John. Welcome to FixYa. The loud pop you heard was more than likely a capacitor exploding. If you have some soldering skills, you can repair this yourself. You must be aware you are dealing with very high voltage here, and can kill you. Make sure the unit is unplugged, and remove the back. Look for any capacitors that are puffed-up or swollen at the top. Look for any parts that may have smoked-up marks on them and replace them with the same Ohm and watt rating as the ones removed. Please note the polarity + and - . You will need a pencil tip soldering iron and solder, and solder wire wick for the job. Get the parts you need here. www.mateletronics.com . Thanks for choosing FixYa. Happy holidays and...good luck.....John

Hi,
Let me know...
- is it Sony KF-50WE610 tv or any other model?
- does standby red light blink?
- if yes, how many times it blinks after 3 seconds pause?
These info will help me to diagnose possible cause of problem.
Thanks.
