Question about Sony Grand WEGA KF50WE620 Television

Open Question

Went to replace the lamp with a brand new one, but the housing has melted. When I installed the new lamp, it would turn green, blink a few times and then turn red and blink. It would eventually turn off. I'm assuming the fan stopped working at some point causing the lamp to melt the housing. What can I do to repair it?

SOURCE: Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

SOURCE: melted plastic where the lamp is positioned

I would suggest to call Sony if you have a safety concern about your TV. A fire hazzard is unlike because most if not all the electronics components or plastics used on TVs have a flame retardant that It will not burst into a flame.
Good Luck.

SOURCE: Sony KDF-42WE655, lamp burrning out and melting.

I am having the same problem with my kdf42we655 model. except I also have the blue/pink blobs all over the screen. Sony came last week to evaluate and were pointing to the amount of dust in the set... What a crock... Dont know what theylle do yet but I am ready to get a lawyer and fight this. They know there is a problem and dont want to back it up... Ill never buy Sony again.. And btw. if your buying a new tv and you a sony fan,. look at samsung.. They are building the new lcd screens for Sony...At least Samsung stand behind there product and costs a lot less than paying for the Sony name..

You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

I bought a mitsubishi wd 52327 new several years ago. I've replaced the lamp once and it worked fine but now it needs to be replaced again. We bought a lamp off EBay w/housing. I installed it but the tv...


Hi Brent, Mitsubishi's have a problem with the power supply and the Light Engine which incorporates the Digital Module of which it has to be purchased as a complete assembly. I sincerely believe you should not put that kind of money into a dlp set. The cost of the light engine is in the area of $1100.00. Your last idea is the best one.

Sony KDS-60A2000 60 in. HDTV Television turns on green and then turns to 3 red blinks a pause and then three blinks again. No picture on screen.


Lamp door is not attached properly (all the way) or lamp door switch is bad (less probable case). Remove lamp door. Locate pin that pushes into lamp door switch. Figure out where it pushes, find switch lever over there. Check if it's broken. Than re-install lamp door carefully and secure with attached screw. Make sure also that lamp door is not melted/deformed in any way. If yes - it's got to be replaced with new one.
Regards.
Russ.

Hello:

Make sure u replace the lamp cover as the safety switch need to be closed to make the set work. If new lamp did not repair your problem , then it may well be the Ballast Board, Sometimes call the Lamp Driver.

The red light indicates the lamp is burned out. A new one is $100 to $200.
Depending on whether you use the old housing or want to order the lamp and housing together. There are lots of sources for this lamp online.

Won't turn on


better to call the manufacturer so they can test it and check for problems. If still within warranty they will replace it, I guess.
