Without diagnosis I would bet on a tuner.. with PIP you have two tuners.  However, check all your cables, with any electronic equipment, we always first start with the simple things and work upward toward more complex possibilities.

No picture on main screen


Sets with PIP use two tuners--one for main and one for PIP---likely the main got hit with the static discharge during the storm----Here we always disconnect both power and cable when a storm.

There is a way around this (will lose PIP) with a cable box connected to the audio and video inputs on rear of set---bypass the tuners and use the box to change channels and provide signal.

let me know if questions.

Signal Problem


Hi,

When the sound is working and the picture is not it indicates the main power supplies are working but the picture supply is not. The picture supply that powers the projection tubes is a high voltage generator and is very expensive to repair. Not even most tv techs now how to troubleshoot them. So, I cannot recommend you repair it yourself unless you are a trained high voltage tech.

The cost of repair - my wild guess - would be around $300. However, the real cost can only be determined by someone who can make an accurate diagnosis - which will require a hands-on approach the problem.

If you have any other problem please ask me..
Goodluck,

Pip working but main screen not.. model pcl541r


If the main channel input is not giving you a picture, you need the tuner checked out or replaced. a good indicator is when you select a channel with the remote you will get just snow(sometimes followed by static in the audio)you do get the picture in picture thru the auxiliary inputs on the tv because they go directly into the audio and video drivers and bypass the RF circuitry. One way of making sure that the tuner is the problem is by hooking up the coaxial out of a vcr or dvd player to the main in or cable in of the tv and selecting channel 3 on the tv and then try a tape or a disc, if you get a picture then suspect something crossed in your installation between pip and main in of your tv set.please your feedback if i answered your question.thanks!

Mitsubishi TV hand me down


the problem you have is the video goes thru the pip board first and the pip board has a problem this is a known problem. the pip board has some capacitors that leak on the board. the model you mention is CS-27MX1 not XM1 but anyway the back casing was made for several sets of that size. so the pip is the problem and the bulletin is as follows;
1. NO MAIN VIDEO,THERE IS VIDEO IN PIP ON EXT1 AND EXT2:-CHECK FOR 1VPP OF LUMINANCE ON PIN 1 OF IC7000, IF MISSING OR LOW CHECK THE VALUE OF C7001 (4.7UF 35V), LOCATED ON THE PIP-PCB.THIS CAP MAY LEAK ELECTROLYTE ONTO THE BOARD AND OPENED A FEED THROUGH IN THE PATH BETWEEN C7001 POSITIVE LEAD AND THE EMITTER OF Q7003 OR CAUSE INTERMITTENT COLOR. PT#181P504090. 2. NO MAIN OR PIP VIDEO, CHECK CHECK C7014, 47 UFD 35V ON THE PIP PCB. PART # 181P502060 3. CHECK FOR 7.2V DC ON THE BASE OF Q7003,IF LOW OR MISSING.CHECK THE VALUE OF R7002 (150 OHM 1/10W).LOCATED ON THE PIP-PWB. PT#103P401050 you can by pass this by removing the pip board and jumping the VP connector pins 7 to 9 and 5 to 11

Pip only on screen


Try hard reset first==Unplug ac cord overnight, then try again.Possible signal board trouble-- Practice visual acuity technique==look for CRT coolant leak on circuit board. Also suspect PIP PCB==can be by-passed by a knowledgible tech.
