YOU WILL NEED THE SPECIAL REMOTE TO DO THIS. AND I THINK SOME OF THEM HAVE ABILITY IN SERVICE MENU TO TURN OFF HOTEL MODE. OR YOU CAN TRY USING ANY PHILLIPS/MAGNAVOX REMOTE WITH THE STATUS BUTTON AND TRY THIS.
PRESS MENU-9-6-5-2-STATUS AND YOU SHOULD BE IN THE SERVICE MODE TURN OFF THE HOTEL MODE

resolder vertical ic chip. that would be ic-401 on that mitsubishi. mch

No the timer circuit would not prevent the Tv from coming on there is logically something else preventing that... The unit is equipped with a shutdown circuit that monitors voltages and prevent it powering up if a certain condition, like a short, is present. Could be the horizontal output transistor is shorted and the shutdown would prevent any B+ from that circuit to prevent a fire. Could be simply that the regulator is shorted and one of the voltages is missing. It's REALLY difficult when the only condition a tech has is that it's dead, or won't power up...
A Mits is a good Tv - really well built. But any good Tv from that era was meant to last about ten years. So when you factor this in your calculations it might just be time to get a new one..
My best suggestion is to take it to a local reputable technician for an estimate. That usually costs something but not an arm and a leg. Then based on what s/he says the problem is and what it will cost to fix it decide whether it's worth it or to replace it with a new Tv...

high voltage transistor cost to repair or regulator, 100.00 to 150.00

I need a password to unlock my Mitsubishi TV Model # CS40707 Serial # 503994

CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB. 2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 (9-VOLT REGULATOR) ON THE SIGNAL PCB.

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems.






Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

CONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Getting the squematic will be the first step to take to become more familiar with the electronics inside,you can ordered by going to http://www.servicemanuals.net/ click on service manuals and give them the model number,they will then give a price and availabilty.The color processing uses a driver for each color and an output for each color too,the output are ussually placed in the crt board in theneck of the tube.the drivers and outputs are transistors most of the time but sometime the drivers are part of an integrated circuit.Please let US know if you need more help but place it as a new question.

I am sorry,in my other response I had this tv mixed with a rear projection tv,the response still applies because one of the transistor in the standing metal plates being held by escrew is the green output transistor and I can see it has 3 of them(one for each color)Look up the number on its face and replace it with an exact replacement or replace all 3 at the same time,it will not cost much.Let Us know how it goes.

Excellent pictures of the crt board I can actually see the transistor ans is mounted in a piece of metal with a screw holding it,is just to the right and he should be the only one of this kind in the board,this transistor is soldered in and it needs to be replaced with same,in its face it has some number ,the part can be ordered or cross to a replacement with those numbers.Make sure all the conections on the board are solid.Let us Know how it goes.

Those are magnets and not outputs ,the outputs you might be looking for are in the crt board and is an actual transistor,do not move the magnets and try to realign to the way they were,the crt board is at the end of the neck of the tube and it can be remove very carefully,do not twist this board or the picture tube might break and then we are in trouble.Take a picture of the board it should be about a 4"x4" in size.Make sure the set is not plug in when you work around this parts.Lets Us know when you need more information.

The lamp is not enabled possibly due to the colour wheel motor not turning. Any broken glass jamming it? Or the lamp ballast has failed due to an old/worn lamp.

Your Mitsubishi VCR HS-U580 looks to have a problem with the information rollers and drum. Here are some things to check: Look for something blocking the VCR or cassette compartment that would possibly be stopping the guide rollers. Check the belt that drives the VCR mechanism. If it is loose or broken, you may also need to substitute it. Clean the video heads using a head-cleaning cassette to make certain they're not dirty. See if the drum motor is working. If it is not spinning, there may be an issue with the motor. If the trouble persists, it's an exact idea to get assistance from a professional technician or contact Mitsubishi's purchaser support for advice. Be cautious when dealing with electronic devices, and if you are not certain what to do, it's great to get assistance from an expert.

i think finding a downloadable service manual for your Mitsubishi HS-U580 VCR might take some searching, but here are a few options: Check the official Mitsubishi website's support section. They might offer downloadable manuals for older models.Many online appliance parts stores like RepairClinic or AppliancePartsPros stock service manuals for various brands and models. Search for your specific VCR model to see if they have it available.Websites like ManualsLib or iFixit sometimes host user-uploaded service manuals. While the availability and quality can vary, it's worth checking. If online options fail, consider purchasing a physical copy of the service manual from online marketplaces like eBay or Amazon. Remember, some websites might charge a fee for downloading manuals. Always be cautious of suspicious websites and download from reputable sources.

Hoping you did not have electric overload that damaged the power supply, try unplugging the set and push the button On until no lights indicate anything. Then wait about an hour so the capacitors would empty themselves further. Next plug it back in and see if this worked. It is never wrong to push the edges a little in finding if the cables that go around the screen have a problem at that point. When one opens the TV (off power and unplugged) these flat cables should be checked for corrosion and right position in connectors. Corrosion is caused by little moist only, combined with the electricity. Then see if capacitors from the power supply, or any at all, have expanded tops. Those are the larger and smaller towers with metal on top that is divided in three parts. New ones alike can then be ordered but replacing requires basic skills. Further examples can be found on YouTube. Capacitors are common to fail early. Those larger ones have dangerous high voltage and can hold their charge for long span of time. it is not uncommon for devices like this to fail after being off.
