Good Day;

I don't think so. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.

I have repaired 50 or 60 of these.

Good Luck, big IRISH.

The tv turns off right after you turn it on. Any suggestions?


I had a similar problem with my 42 in Philips LCD HDTV.



Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.

1. Have it fixed by a professional

2. Open your TV and find PSB. Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


I have a tip/tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem.


Hope this helps and Good luck.

No sound or picture on mitsubishi


Some simple things to look at but they envolve getting at the main boards; it means someone has to unbolt the main chassis and examine it.

What happens a lot with these older sets is bad solder connections develop.

A lot of the problems are easy to see and begin in the power supply looking at all the 3 lead devices--let me know how much expertise you have I would be happy to help you.

The picture on my Mitsubishi Model VS-45607 is not staying on track and scrolling continually


Good Day,
It sounds like you have a bad cap or IC. Replace C2P05 100 ufd 16 volts, off Pin 3 of IC2P01. It is on the Signal Board. IC2P01 Part # 270P466020 (stand-up type mounted on heat sink). The Signal Board is the the board on the left hand side looking at the TV from the back. The parts are on the right side of the Signal Brd towards the middle and back. Replace it even if it checks good. Look at other Caps in the general area and if you see black stuff on the negitive leg of those caps(replace them also).

Good Luck, Big Irish.

Screen seems to have convex curves at the top and bottom of the screen. had it repaired once 3 years later the same thing. took the tech that came to the house said the heat expands the connections on the...


If it is convergence and was soldered once--it will most likely need the convergence chips replaced--this model uses two STK-392-570 chips----even if bad soldering was the first problem based on the fact that the set is a 2001 model--should have just replaced the chips then as the amount of work to get at them to solder is the same as changing them--if the chips are replaced the set should be good for 5-8 years--not 3 years.

Let me know if you have questions or need advice.

Timer led blinking fast, not going out.


listen? these sets now have all kinds of troubles--some if the green light will not stop blinking have several filter caps on power supply board that are buldged up--top of them is pushed upwards--they also have problems on two other boards--one part of the optical engine and the other a board sandwiched between two other boards--most caps are soldered thru the board--the ones on the other two boards are surface mounted caps--soldered to the top of the board--best case thing for you is have someone remove power board(it is on left side as you look from back) and see if caps are buldged up--if you are lucky there should be 4 or more bad--If I owned this set and replaced them and set worked--I would sell set as fast as I could---if caps on power board are not the problem--buy a new set---do not take my word for this: google model number with word problems after it and you will get an education.

Power button flashing but tv won't turn on


If the power light is constantly flashing even after you have unplugged the set for a min or two and the plugged it back in, the you will need to replace 4 capacitors on the "DM" board. The "DM" board is located under a metal shield on the left side looking from the back of the TV with the back cover removed. They are 1000 microfarrad and rated at 16 volts DC. Available from radio shack or just about any electronics part supplier. Once you look at the circuit board, you will see the defective ones, they will have the tops swelled up. You will need at least a 40 watt soldering iron, .032 solder, and "solder wick" to do the job. Make sure you get the polarity straight when instaling them. If this explanation is too technical, then call a repair shop and ask then how much to replace the 4 capacitors on the "DM" board.

the chances are you may have what is called a bad hypermodule. it is a signal board that controls signal processing. does the picture apear"wavy" then clears up. The way to repair this is to repair this board is to replace 11 microcaps. NOT EASY technicians have truble with this repair... twezzers and manifying glasses. ideally the best thing to do is to replace this board... but they are very rare and difficult to find. so if you can find a good tech that can solder microcaps or if you can find the board those will be the options

Shaking screen


Check the 9v regulator Ic2p01 on the signal board for correct regulation 8.9 to 9.1 volts. If voltage at the output is under 8.9v, replace the regulator Ic. Always replace C2p05 100 Ufd 16 V on this set and that should take care of the shakes but you may want the tech to go ahead and ESR some of the other troublesome caps throughout the Tv. He'll know what you mean. Many of the 100mf caps replace automatically. Several others will have a questionable ESR and should be replaced. Caps are inexpensive, but probing with an ESR meter is somewhat labor intensive so you miht discuss with the tech just how far you want him to go testing for bad caps.
A Mits is a great Tv and this repair is clearly worth it..

Power but no picture or sound


Is hard to tell if the set is going to need parts or not,maybe not,since you protected the set from dust is not likely the cause of the problem,after a while the units develop loose conections because of the heat dissipation some components have and the solder conections become loose.Be safe and seek assistance if you are not too familiar with tv service.
