Tv won't turn on. replaced bad caps and after some testing it turned out that the power supply board wasn't giving the supposed voltages.


This problem is not easily to be solved.Tries to changes all the capacitors components even if u think is good around the bad capacitors surrounding area.After that,if u still have the same problems.This problem could be any high voltage components parts like transformers to ICS power regulator.Trying to fix this power supply board probably beyond your ability and u must also have the tv power supply board original schematic and electron scope too . .To measure those power transformers and ics power regulator output.Tries websites like Shopjimmy.com,EBay.com to buy a whole new refurbish tv power supply board for the replacement that is ur best bet.

Red light won't turn to green


This is a common problem. There are several capacitors on the power supply and logic board that are bad. Replacement of these parts has restore all units that I have looked at.

On the power supply I would replace at a minimum:
C14 - 4.7ufd 50v UPW1H4R7MDD
C4 - 1ufd 50v UPW1H010MDD
C8 - 100ufd 25v UHE1E101MED
C10 - 470ufd 16v UHE1C471MPD
C12 - 1000ufd 10v UHE1A102MPD

There are 4 others in the supply that were not grossly bad.
C1 - 22ufd 400v EEU-EE2G220
C7 - 220ufd 25v UHE1E221MPD
C11 - Same as C10
C13 - Same as C10

Logic board:
E5 - 33uf 35v EEU-FM1A471
E6 - Same as E5

Part Numbers of replacement caps are Nichicon or Panasonic.

Note: Caps on the logic board are extremely hard to replace due to the internal ground plane.

I have a mitsubishi vs-4541/4542 tv with sound and no picture. What are my options?


I have not repaired this particular model. If this TV is a projection set,you have one of two possible problems. First....You may have convergence IC that has lost a ground contact to the signal board. We are discussing the board that has all your RCA connections and RF connectors. You may have to replace, possibly a STK-XXX series convergence IC. One or two capacitors near this IC, usually a bad cap will end the life of an IC and resistors. And replace a couple of resistors, these are standing tall next to the convergence IC. The next problem could be on the power supply. The power supply will almost always have the flyback transformer on it. If you can locate the vertical IC..This IC may need resoldering. You will see rings around the pins of the vertical IC. Replace the three or four capacitors next to the IC. A bad capacitor will overheat an IC and cause solder grounds to separate. Thanks for asking and show a few hands of support!

Sharp AQUOS LC-32D44U 32 in. LCD TV turns off after a few seconds


Hello,
Its the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.
Hope this help in solving the problem, take care

LC-46D43U Lcd display broke on inside. The screen is fine. Have sound no picture, just a bad spot and some lines. How can I fix this?


If the LCD Display is broke, only replacing the LCD Panel will fix it. The Main problem is that the cost of doing this would exceed the cost to replace the whole unit. I am sorry about the bad news.

The rca tv will not power up 55 inch


Is it a rear projection set? or LCD? If it is a projection set it could be a bad High voltage splitter. Part is about $30 If it is LCD it could be a bad power supply or inverter board. A good tech can replace capacitors in power supply without replacing the board

Directv DVR R15-500 problem


I had a similar problem the orange record light was on and the unit could not be turned on. I didn't want to replace the unit since all recording would be gone. After some googling I found that the problem was related to the power supply. I found three capacitors with swollen tops 2 1000uf@10V and 1 1200uf@10v. I replaced them and everything works again.

Ricoh Aficio CL3500N error code SC581


Q1 - Possibly, I have not seen an SC581 error before. Usually using too much power would give you something like an SC240 error "Power Supply Excessive". So it depends on the extent of the damage. You could also have to replace the main board, motors, etc.

Q2 - You will have to pull back the feeder tray, remove the back panel, there is a cover over the main board and the power supply is below it and fairly easy to get to. But if other components were damaged it could be a much more involved repair.
