I have had this 45" TV since new @ 10 yrs. Picture is still good. My problem is the brightness adjustment is maxed out. also TV takes longer to come on and sound takes @ 20 minutes to come on and work properly.
Trying to get an idea if worth repair expense or just buy another tv.
I know nothing about tv repairs but if just a matter of changing a module or lamp...plug in or unplug...simple enough.....Nobody has ever serviced this TV. Never has needed servicing.
Thanks for the advice.

Re: Mitsubishi 10 yr old rear projection
Well, there is no lamp or simple part you can unplug and plug in. I have seen a couple of those sets with that symptom recently and it is caused by a faulty 9 volt regulator on the small signal board. This is not an easy part to change and the repair should absolutely be handled by a tech experienced in Mitsubishi projection sets.

This tv have no colors wheel or projection lamp.Tv only have 3 CRTS tubes like R,G,B CRTS tubes guns.Problems of the tv?Will help u diagnose and replaced parts or telling should be repair by a tv Tech.
The Main issues with the Mitsubishi HDTVs that size are the projection bulbs in the rear. A large TV like the Mitsubishi can allow dust build up on the lamps and the mirror in the rear that projects the picture to the screen. An easy fix would be to clean off the dust off of the mirror and bulbs. You would need to go through a tough processto do this since the mirror can be quite heavy and is in an ackward place. The only other alternative would be the need to replace the projection lamps themselves which can cost any where fromm $150 - in some cases $300 a piece for the lamp itself. The Television is still a great set but can cost quite a bit right now to fix if the problem is with the Lamps. If you can afford the Lamp replacement if it is needed the set would last you another 10 years plus. If you wouldn't like to go through the hassle of repairing the set or finding a place to repair the set there are so many new sets out in the market that will give you an amazing picture and quality.
Rca Screen ControlThese sets have screen control adjustment usually located behind the speaker grill(pops off -velcro or press tabs) and convergence front board. There are 6 contols on a black molded assembly about 31/2"x21/2" square. adjust only the top controls marked "Screen R G B" the bottom ones are focus Method: -turn on set and let warm up for 30 min at least -switch tv to blank unused video input channel -adjust each control in turn until you see the picture glow (with the corresponding color) and slightly back off the control - repeat for each color - this will increase screen brightness and ballance your color Hope this helped.
The TV does have a screen control on each of the picture tubes ( there are 3 ) although I do suggest you have a qualified technician make the necessary adjustments as an improper adjustment can cause damage to the set. Should you deside to make these adjustments yourself, you'll need to remove the back ( or front in some sets) ( PRE-CAUTION, UNPLUG THE SET FROM THE WALL BEFORE PREFORMING ANY ADJUSTMENTS INSIDE THE SET ) The screen adjustments are located either on the bottom of each tube or in a group component located where the main High Voltage Wire ( large red wire from the black transformer on the deflection board ) is connected to. Look for a turn pot ( screw type adjustment ) that is marked SCREEN. When you locate it ( whether it be on each tube or in the group component ) turn it up only slightly and not to much, as excessive gain ( turning it up to much ) may cause the TV to shut down. When you have the proper brightness ( when it looks good to you ) close the set up and enjoy the renewed picture. Good luck and I do hope this has helped in some way
