Question about Televison & Video

1 Answer

I have a Philips Cineos Mod# 44PL9523/17, my picture is getting dark, I'm not sure when this started. About two months ago the Lamp Warning Light came on, so I replaced the bulb, this did not help. The screen is even darker around the edges. The TV still has a good picture, but I have to get it as dark as I can in the room to watch it comfortably, It started this about a year ago, could it be I have the wrong bulb or do you think I have a more serious problem? Thanks

HI,

There also seem to be a capacitor(it is the 33 uf/160 volt cap) in the high voltage line which after replacement may lighten up your set...

Remove the back panel of your TV, on the D board you'll find an electrolytic capacitor. If you don't easily see the D stamp on the board you'll know you're on the right board when you're in the 500 series position numbers. On the cap will be the markings 33uf/160v and it's polorized so there is a positive and negative. The new cap has to be placed in the circuit according to its polorized direction and the cap indicates which side is negative... You can easily other see caps on the board and what denotes their negative side with relation to the direction on the board. Usually, the negative side marking on the board will have a small box or block near the hole opening denoting negative
.
A single cap like that can be purchased from your local electronic supply store. Just tell them you want a radial 33 micro ferret 160 volt electrolytic capacitor. Should be about 3-4 dollars... If you try and buy these from a wholesale distributor you'll get a better price but usually you have buy minimums to contend with..Chenaging this capacitor would solve your issue...

Please leave me comment, if you need further assistance

I have a mitsubishi WD- 6oc9 tv when i power my TV i get a steady blinking light and no picture. my husband replaced the lamp about six months ago. dont think thats the issue. need ideas on how to repair.


Sounds like lamp needs replaced. If you purchased a cheap lamp from ebay or your installer did, that is about all they will last. On your next lamp buy an osram or Philips lamp. They are a lot better quality.

Power light glows orange for a minute then shuts down without ever having a picture or sound. I have replaced the lamp and clean the filters. This is a Philips Cineos Lcos 62 inch.


Watch at turn on to see if lamp fires up for even a second or two--if not either a ballast or the control that turns it on has detected another issue and is not allowing the lamp to come on.

Ihave a Philips 50PL9126D tv and I just replaced the lamp because the picture was very dark. I can see the picture but it is still somewhat dark, bright in the middle,dark at the edges. I tried to adjust...


Sounds like you may have the wrong lamp. Make sure you purchased a Philips lamp that's 100% compatible with your television model. Philips pioneered that lamp, so naturally they make 100 different types for DLPs and LCD projections.

You may have an elliptical lamp instead of parabolic. The lamp for your TV should read P22h.
