Question about Mitsubishi VS-45605 50" Rear Projection Television

2 Answers

Vertical problems I have a VS45605 which has vertical problems. Tech said my two amps on big heat sinks are shorting and need to be replaced. labor $150 plus $149 for each part (2) Does anyone have a schematic or know part numbers of what looks like powerpacks sandwiched on a board with lots of heat sinks?

    hit the resets for convergence, now I have three rolling menus etc. my verical lines are rolling up and I am misconverged but still moving (rolling) tgryied boath convergence resets. After reset of convergence I get a green grid that is tearing at the top and trying to roll up

    Troylove11: Thanks for the information. I will first resolder the legs of the STK's. Do you have a copy of those "Menu 123...456576" reset codes you can email me? I reset and wiggled heat sink board, rolling stopped etc but returned. Your codes make it much easier to converge rather than the non service convergence proceedure. tThanks in advance,

    Troy: thanks for all the input.  I have replaced the STK's.  Convergence is now almost perfect.  Problem is that we still have vertical rolling and tearing until warm up..  Then intermittant.  Problem occurs mostly on Video in, only intermittantly on RF.  When I heat up (with hair dryer) the Main PCB behind the RF inputs and Video inputs (part of the board encased in cover with holes) the problem goes away but come back after it cools for a minute or two. I took the main board out again to see if any obvious burn problems, but no.  Replaced and tearing has come back.  Only hear on the part of the main board with cover seems to bring it back to normal.  I have PDF of manual and have traced from RF input to board to no avail.  Help.  I will send you Mits manual if you need it.  4 mg or less if you have RAR  Thanks in advance.  I have attached photo of tearing.

I have the same problem and I replaced the stk's and the ic's and 20 caps and 10 or so resitors and it's still there. Do you think the problem is under that cover.

This sounds like convergence amps not vertical, what was the set doing prior? If convergence amps first check: E2RESET DOES NOT RESET THE CONVERGENCE. THE CONVERGENCE CAN BE RESET BY PRESSING "MENU 12598970", IF THIS DOES NOT RESET THE CONVERGENCE TRY "MENU 125968970

    Well if reset does not do it then it need convergence amps like tech says. Part numbers are on amps. These are big STK's on heatsink board. You can order from MCMelectronics, Tritronics,, etc

    Just remember not to bridge the pins when you are soldering. Look also for loose wire connections. Make sure they are all tight. I don't have a list of codes only what I have given, but would help all I can!

Vertical size of screen is bad. very big. please solve this problem.

You have too much vertical scan amplitude this could be due to higher voltage on dc line to vertical amp or broken amplitude control , maybe short circuit capacitor on feed to scan coils, or transductor open circuit windings , could also be open cct in negative feedback loop.

I don't have the circuit diagram in front of me, but I would suspect a shorted or leaky capacitor in the output circuit. Another possibility is that the heat sink is inadequate or something is amiss with the thermal interface between the IC and heat sink.

Is the vertical waveform normal? Put a convergence pattern up and see if the grid is linear from top to bottom. This could give you a clue.

ur tv has problem with vertical scanning section. may be dry soldering or vertical output ic faulty.
check for any dry soldering in that section. mainly the soldering of vertical ic. if see or not re-solder the leads of the vertical ic . then check is the tv is ok or not. if complaint remains replace the vertical scanning out pout ic. it will be fitted on a aluminum heat sink in the vertical section. u can see the heat sink on which the ic is mounted in the picture ( in side the small green circle). if u need more assistance feel free to contact through fixya.

that is usaually a component in side the board called a capacitor that bursts due to high voltages passing thru it. so u will need a technician to replace it for you at a cost

57H81Toshiba Blue Line not straight

You have a bad convergence output IC in the blue vertical circuit. On the bottom side of the chassis you will see a " V " printed by the heat sink. You will need to unsolder the heat sink and the 20 pins on the IC to remove it. Replace with STK 392-180 (sanyo) if possible or STK 392-150. Looking from the rear the heat sinks are big aluminum finned rectangles. There are 2 heat sinks one marked H and one Marked V. Even though you have a horizontal line your problem is in the vertical IC. Be sure to use a liberal dose of heat sink compound.

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace. You'll need to take your set to service center to have it serviced.

Good Luck!

You might have bad solder joints on the vertical output IC. I do not know where it is located in this set only that it will be mounted on a metal heat sink near three wires that have identical plugs which go to the deflection yokes on each crt tube. Sets vary as to placement of vertical IC. Solder joints should be easily seen if you have good eyes or use a magnifying glass. I do know that the vertical IC will be on the board that has the highvoltage transformer on it (has big red wire). You may have to unplug the board and turn it to the soldered side or just turn the entire chassis up 90 degrees to see the connections. If this is not the problem I don't know how to get into the service mode at this time.Hope this helps

RCA P46770CK

Check Cr4503 in the vertical circuit for short or leaking. The convergence circuit is most likely fine. Also check for any leaky electrolytic caps in the 500 block. (example) CR4503 will be printed on the PCB as CR503. The vertical circuit is located in the center of the chassis behind the big aluminum heat sink.

Distorted picture

The RCA P52960 uses the PTK195 series chassis. There are 2 main boards at the bottom of the set and above the board on the right (when viewed from behind) is the convergence power supply board. This board usually has a big black IC on it, labeled STK730-010 and bolted to a metal heat sink. Chances are, that IC has burned out and stopped working. Replacing that IC should restore your convergence. If you do not have experience replacing IC's in projection sets, allow a qualified tech to handle it for you.
